1 Introduction

1 Introduction

The application-oriented parameterization of digital inverters is gaining in importance as thenumber of inverter functions increases. In addition to traditional drive tasks, the drive inverter hasto handle more and more application-specific control tasks, thereby relieving the higher-levelcontrol system of drive control functions, which are often time-critical. This shift in control taskstowards the drive inverter results in a completely new approach to improving the interface betweenman and machine.

The increasing complexity of drive applications requires the commissioning engineer to have aprofound understanding of and a lot of experience in control technology. Drive performance inthese demanding technical control processes is usually optimized with additional aids, e.g. storageoscilloscopes or analog value recorders. To make these complex drive applications easier tohandle for the commissioning engineer, additional tools are needed that enable commissioning totake place rapidly and simply.

With the MOVIDRIVE® drive inverter series by SEW-EURODRIVE you no longer need additionalmeasuring instruments to commission inverter drives. All you need to commission the drive andoptimize control-specific parameters is a laptop (PC) and the MX_SCOPE user software, whichallows you to measure, visualize, log, and document the drive application, in addition to setting andediting the drive's parameters.

The MX_SCOPE user software, i.e. the MOVIDRIVE® oscilloscope, allows you to optimize a driveapplication yourself, e.g. by applying a setpoint step change. The response functions are thenrecorded in the inverter in real time. The information obtained can then be transmitted to the PC viathe inverter's serial interface and displayed in wave-form on the monitor. This provides you with upto five traces displayed in different colours on the screen. Similar to an oscilloscope, both thehorizontal and the vertical axes can be expanded and compressed with the different oscilloscope-type functions offered by the software.Furthermore, MX_SCOPE offers the user the facility to record digital input and output signals fromthe inverter in a simple way, so that complete program sequences of the higher-level control sys-tem can be recorded and then analyzed.

Functions such as save, document and print facilitate documentation of parameter settings andmeasured data.

Simple mouse or keyboard operation, supported by icons and on-line Help features makeMX_SCOPE a simple-to-learn, easy-to-use tool.

MX_SCOPE is used to visualize and optimize drive control parameters. Therefore, only the mostimportant parameters which directly affect drive functions are accessible. For complete parameteradjustment of the inverter, the MX_SHELL user interface must be used.

The MX_SHELL program can be started directly from any menu item (→ Sec. 5.1.6 and 5.4.3).

Introduction 1

Special features

Whereas the functions for real time recording of measured variables are stored in the inverter'ssystem software, the MX_SCOPE user software is the interface for configuration and visualizationof the process data. This provides the user with a powerful MOVIDRIVE® software oscilloscope.Major MX_SCOPE features for the MOVIDRIVE® inverter include:

• Simultaneous real time tracing of 4 measured variables (4 channels)

• Free choice of measured variables, e.g.– actual speed / setpoint speed– output current– ramp generator inputs / outputs– inverter utilization – DC link voltage– input/output signals– ...

• Variable sampling rates from 1 ms to 1 s

• Recording depth of max. 2048 sampled data points per measured value channel

• Recording times from 1 ms to 2048 s

• Pre-trigger function to record pre- and/or post-event history

• Edge-controlled triggering

• Variety of trigger sources including, e.g.,– PC (manual)– input terminals– output terminals– inverter faults– reference signals

• Individual print function for detailed system documentation

2 Quick Guide to Using MX_SCOPE

For a more detailed description of the individual steps please refer to the following sections.

Establishing the communications link

• Switch off the inverter and the PC.• Connect the two units via their RS-232 interfaces.• Switch on both units.

Starting MX_SCOPE

Start the MX_SCOPE user interface.Select the PC port to which you have connected the inverter in the [Communication] / [PC-Inter-face] menu item.Set the MOVIDRIVE® address to “Point-to-point” in the [Communication] / [Connect] menu item.

Open the “Scope settings” window in the [Parameter] / [Scope setup] menu item. If thecommunications link has been established correctly (all controls are visible), you will see the activesettings on the screen.– Sample time [ms]: 1– Pre-trigger [%]: 0– Trigger source: PC only– Trigger edge: 1/0

Starting tracing and reading measured data

• Click on “Trace = Start” to start the tracing process. The LEDs will signal the recording status of the inverter. The “TRACE active” LED indicates that measured values are being traced. At the same time, all buttons are greyed out to indicate that the sampling criteria cannot be manipula-ted while tracing is ongoing.

• After approx. 2 seconds, the “TRACE overflow” LED indicates that the measured value buffer has been written completely once. From this point onward, MX_SCOPE can use the complete trace buffer. The buffer is constantly overwritten until the tracing is stopped with the selected trigger source.

• Important: Do not change the settings any more after this point.• Press <F3> to activate the trace data transfer.• When the trace data transfer is complete (this should take approx. 40 seconds), the traced

measured values are displayed in the main program window where they can be edited if required.

• The [File] / [File Info] / [Settings... [F2]] menu item shows the tracing criteria and MOVIDRIVE® parameters which are active at the time of trace data transfer. You may now add your own com-ments and save the data with the [File] / [Save as] command.

Installation 3

3 Installation

3.1 Supported MOVIDRIVE® types

The MX_SCOPE process data visualization software can be run on all MOVIDRIVE® drive invertersand is compatible with all the option pcbs available for the MOVIDRIVE® inverter series.

3.2 Hardware requirements

• PC/AT with 80386 / 80486 CPU (mathematical co-processor recommended)ideal system configuration: 80486 DX33 and higher, 256 K cache memory

• Minimum 570 K RAM• 3.5" disk drive (1.44 MB)• Approx. 2 MB free hard disk space• MS-DOS operating system V5.0 or higher• VGA compatible video adapter• RS-232 serial interface to connect the MOVIDRIVE® • Serial mouse

MOVIDRIVE® and the host PC are connected either via the RS-232 or the RS-485 serial interfaces.To establish a communications link via the RS-232 interface, the inverter must be fitted with theUSS 21A (RS-232 and RS-485) “Serial interface” option. You will further need a standard serialinterface cable (shielded, 9-pin type D male-to-female), which should not exceed 5 m in length. Toestablish a communications link via the RS-485 interface, the PC must be fitted with an RS-485interface. On the MOVIDRIVE® side you can either use the standard RS-485 interface (X13:ST11/X13:ST12) or the USS21A option.

Important:Before you connect the MOVIDRIVE® to the PC, make sure that both units are switched off!Failure to do this may result in undefined system conditions.

3.3 Installing MX_SCOPE

On the MX_SCOPE floppy disk you will find, among others, an installation routine (INSTALL.exe),which will copy all the files to the hard disk directory you have specified. After you have insertedthe floppy disk, start the INSTALL.EXE routine by entering:C:\>a:install <Enter>

Then follow the program's installation instructions. For further information please read theREADME files.Unless an MX_SCOPE directory already exists on your hard disk, the installation utility will nowcreate one for you and copy all the files from the floppy disk to this directory. When the installationis complete, your directory should include the following files:

ADAPTER.EXE Utility to match the video adapterADAPTER.PRO Current graphics driver fileHARD COPY.PRO Current printer driver fileHCSELECT.EXE Utility to select/configure the printer driverINSTALL.EXE MX_SCOPE installation fileMX_SCOPE.EXE MX_SCOPE program fileMXSCOPED.UIT MX_SCOPE text file (German)MXSCOPED.UIR MX_SCOPE resource file (German)MXSCOPEF.UIT MX_SCOPE text file (French)MXSCOPEF.UIR MX_SCOPE resource file (French)

3.4 Starting MX_SCOPE

Change to the MX_SCOPE directory:C:\MX_SCOPE>MX_SCOPE <ENTER>

No additional parameters will be evaluated. As MX_SCOPE will take up the majority of your mainmemory (min. 560K) you may run into problems if you have opened other memory-resident pro-grams. To have as much memory space available as possible, you should not start MX_SCOPEfrom other programs (i.e. PCSHELL, NC, DOSSHELL, Windows DOS Box).

3.5 Serial communications link

All MX_SCOPE windows with a red header use the communications link with the MOVIDRIVE®

inverter. In the absence of a communications link between the PC and the MOVIDRIVE® inverter orin the case of a faulty link, the corresponding controls in these windows are not active, i.e. they aredimmed (disabled). In this case, the displayed values do not reflect the actual inverter values, theyare substitutes. If you don't have a connection or if your connection is faulty, please check thefollowing:

Interface cable

00996AENFig. 1: RS-232 connection of MOVIDRIVE® and PC

PC interface

Make sure that the serial interface cable is connected to the correct COM port of your PC. Checkwhether the correct COM port is set in the [Communication] / [PC-interface] menu item.

Communications address

If several MOVIDRIVE® units are connected via the RS-485 interface (multipoint connections), thena unique address must be set for each unit (P810). You may choose any address between 0-99.Check in the [Communication] / [Connect] window whether all connected units can be accessed.

RS-485 connection

When you use the RS-485 interface, check whether the ends of the two RS-485 lines are connectedcorrectly. The terminating resistors are integrated in the interface options, i.e. when networkingseveral inverters via the RS-485 interface, no external terminating resistors must be connected tothe MOVIDRIVE® inverters.

Windows 95

Under Windows 95 the serial interfaces are permanently assigned to an application. This meansthat the MX_SHELL and MX_SCOPE programs cannot be run in parallel (in two DOS boxes). Usethe direct program call via [File] / [MX_POS], [File] / [MX_SHELL] which is integrated in theprograms to switch between these applications quickly.

3.6 Utilities for printer and video adapter

MX_SCOPE runs in graphic mode with a resolution of 640x480 dots and 16 colours. This standardIBM VGA setting is supported by all VGA compatible video adapters, it is the default setting whenMX_SCOPE is started up. The default printer setting is HP DESKJET. If your PC configuration isdifferent from the above, use the ADAPTER.EXE utility (to match the video adapter) and theHCSELECT.EXE utility (to select/configure the printer driver) in order to modify the settings to suityour specific platform. The utility programs (dialogs are in English) are part of the LabWindows®

software package by National Instruments Corporation.→ Sec. 6, MX_SCOPE Files

4 Main Program Window

4 Main Program Window

After starting MX_SCOPE the main program window will come up on your screen (Fig. 2). At thetop of the screen you see the menu bar, which is either operated with the mouse or from the key-board in accordance with the SAA standard. At the bottom of the screen is the status and informa-tion line containing information about the program version and the program status. The majority ofthe screen is taken up by the oscilloscope display (plot area), where the acquired measured dataare displayed in wave-form. The bottom part of the screen is taken up by the control and displayelements required for analysis of the measured data.

01324AENFig. 2: The main program window

4.1 Status- and information line

This line provides the following information:

• The program is running in local mode (=OFF-LINE) or it is connected to the MOVIDRIVE® inverter (=ON-LINE).

• The MOVIDRIVE® address which is set.• Operating conditions of the MOVIDRIVE® , e.g. CONTROLLER INHIBIT, ENABLE, TECHN.

OPTION.• MOVIDRIVE® type.• Drive signature, editable in the MX_SHELL program (max. 16 characters)

4.2 Oscilloscope display (plot area)

The oscilloscope display (plot area) takes up the majority of the screen. In analogy to the design ofa hardware oscilloscope, the display is divided into 10 vertical areas (divisions). The horizontaldivision depends on the amount of measured data displayed.

A maximum of 5 channels can be displayed at the same time. The X-axis readout is a measure oftime. The Y-axis has no particular readout, as measured values with different measuring ranges/units can be displayed. As a general rule, the centre line represents the absolute zero line for all

MX_SCOPE 11

Main Program Window 4

measured variables. Accordingly, the upper five divisions represent the positive value range, thelower five the negative one. The assignment of measured value trace and measured variable is evi-dent from the trace colour.

All measured variables with the same unit of measurement are grouped in one scaling group. Foreach group a scaling factor can be set in the control panel area of the main window. This factorallows the traces to be expanded or compressed vertically. Setting the value range per division alsoprovides a reference to the real measured value.

For an exact measured value analysis two zoom cursors (white) and one measured value cursor(yellow) are available. The zoom cursors serve to zoom in on any trace section horizontally (Zoomin on X). The measured value cursor allows you, relative to the sampling instant, to read out indi-vidual measured values (please also refer to the Section “Plot area control”). In addition to usingthe yellow measured value cursor, you can click on the “Measure” button to activate a differentialmeasurement (delta x or delta y) if you wish to carry out a more detailed analysis (see also Section“Differential measurement”).

Control and display elements

The lower section of the main window contains a panel with various control buttons and displayelements, which are required for measured value analysis.

Table 1

MX_SCOPE's control of these elements includes a plausibility check, i.e. the user can only operateelements whose operation actually makes sense given the respective program status. If no meas-ured data were acquired, for example, the Re-trace function cannot be activated to start off with.For details of the controls see the tables below.

Table 2

Six display elements (→ table below) provide information about the time axis X and the assign-ment of measured value channels Y1 to Y5. Sampling instants are plotted on the X-axis. While theX-axis legend in the oscilloscope display area indicates the number of data points sampled, i.e. notthe real sampling time (!), the measured value display for the X-axis reads the real sampling time inthe unit [ms] relative to the sampling instant furthest back.

Control Function: Scaling factor Value range / DIV Type of control

To select the sampling instant on the X-axis, move the yellow measured value cursor. The meas-ured value display will then show the values of the measured variables traced on channels Y1 to Y5at that point.

Table 3

4.3 Measured value selection

Click on the “Y-selection” button to select the measured variables which you wish to display inwave-form. The “Measured value selection” window will appear (Fig. 3). It contains a selection panel where all selectable measured variables are displayed. You can nowassign a measured variable to each of the five channels or close one or several of them (No meas-ured variable).

To display individual terminal signals on your screen, select the Input/output terminals measuredvariable. A new window will open listing all the terminals available. You can now select a particularterminal. The signal which is routed to the input/output terminal is now entered as measured varia-ble in the selection window.

Main Program Window 4

4.4 Differential measurement

The differential measurement function is activated with the “Measure” button in the main programwindow (Fig. 5). The SEW logo is then replaced by a numerical display of the differential measure-ments (Fig. 4) and the white zoom cursors are displayed as cross hairs. The white cursors nowserve as differential measurement cursors, with which the differential measurements delta x anddelta y can be implemented.

00366AENFig. 4: Numerical display of differential measurements

As the X-axis represents the sampled data points, it is generally possible to specify delta x, i.e. thetime difference between the two differential measurements cursors. On the other hand, a delta ydifference measurement can only be made between two measurements in the same measurementunit. The measurements for the left-hand and right-hand differential measurement cursors arespecified in the numerical differential measurement display.

As only one Y measurement can be displayed for each differential measurement cursor, these lockinto the traces. The colour of the measurement background and the designation in the display fieldfor the Y measurement give information on the variable measured.

All five traces are displayed in the display area. The left-hand differential measurement cursor locksinto the trace for the “Actual speed [rpm]” measured variable, which corresponds to the colourblue and therefore the designation Y1. In the numerical display field, the field for the Y measure-ment of the left-hand cursor bears the description Y1 and is highlighted in blue. This enables themeasurement to be clearly allocated to the measured variable at any time. The table belowdescribes the display elements for differential measurement.

Table 4

The differential measurement cursors can be positioned using the mouse or the keyboard. If youuse the mouse, you can click on the cursor you wish to move, and, keeping the left-hand mousebutton depressed, drag it to a different position or a different trace. The display will automaticallyrecognize the left-hand and right-hand differential measurement cursor, and, where applicable, willswitch over. If you use the keyboard, you can use the ARROW RIGHT/LEFT/UP/DOWN keys tomove the active cursor and/or activate the next cursor by pressing PAGE UP/DOWN. The key com-binations SHIFT + PAGE UP/DOWN furthermore enable you to lock the differential measurementcursor into a different trace. This is of particular importance when the traces are so close togetherthat it is no longer possible to position the cursor using the mouse. It is also possible to zoom in a horizontal direction during differential measurement. To do this, thearea in which you wish to use the zoom function must be delimited with the two differential meas-urement cursors in a similar fashion to the zoom cursors.

4.5 Calculation function

The calculation function is activated with the "Calc." button in the main program window. The meanvalue and the r.m.s. value of the measured values between the zoom cursors are calculated.

These values can be used to determine the thermal capacity of the drive.Example for determining the thermal capacity of a servomotor

As current and torque dimensions are directly proportional in servo engineering, the evaluation ofthe effective current can be used to directly determine the capacity of the motor.

You can recognize the speed trace by its trapezoidal wave-form (it is marked with the square sym-bols) as well as the actual output current trace of the inverter. You can determine the r.m.s. valueand the mean value of the above measured values by clicking on the "Calc." button.

01696AENFig. 7: Window showing the calculated effective values in the cursor area

16 MX_SCOPE

4 Main Program Window

The calculation gives the following results:Effective value of the output current (%I) = 45 % (of the rated current of the inverter)

= 0.45 x IN_I = 0.45 x 12.5 A = 5.6 A

Mean value of the setpoint speed (1/min) = 773 1/min

Therefore, the capacity of the motor is calculated at

Meff = MN x Ieff/INMeff = 18 Nm x 5.6 / 12 A = 8.4 Nm

This gives a drive capacity of 8.4 Nm / 18 Nm = 46.7 %

Example for the determination of the thermal capacity of an asynchronous motor:

When determining the thermal capacity of an asynchronous motor, it must be taken into accountthat motor cooling decreases at lower speeds in drives which are not equipped with a forced cool-ing fan.The torque which an asynchronous motor can permanently provide at zero speed is, therefore,approximately half of its rated torque.For determination of the capacity, the mean speed must also be considered.

Menu Bar Elements 5

5 Menu Bar Elements

The main menu comprises five menu titles: [File] / [Parameter] / [Communication] / [Options] / [Help]

The menu options of the main menu can be activated with the mouse or from the keyboard [ALT +1st letter of the option].

5.1 File

The [File] menu title is the interface to the PC environment and includes the following functions:

[Open] / [Save as] / [File Info] / [Load inverter-data] / [Print] / [Start MX_SHELL] / [Exit]

5.1.1 Open

The [Open] menu item allows you to read in measured values from a file, enabling you to docu-ment and edit system data off-line, without a communications link to a MOVIDRIVE® inverter.When you select this menu item with the mouse or from the keyboard, a file selection windowopens (Fig. 8). Use the “Select” button to select the file you wish to open, or click on the “Cancel”button to exit the file selection window without loading any measured data.

If you haven't saved the acquired data yet, the program will ask you whether you want to savethese data or not.

01380AENFig. 8: The file selection window

5.1.2 Save as

The “Save as” menu item allows you to save the acquired measured values and the parameter file,which is active at the time of recording. Selecting this menu item will open a file selection window,prompting you to enter the name of the file to be saved. The program will only accept *.SCO as fileextension of MX_SCOPE measured value files. After you have entered the name of the measuredvalue file you wish to save, MX_SCOPE will check whether a measured value file of that namealready exists. If it doesn't, MX_SCOPE will prompt you to enter a system-specific comment in theprogram's documentation window and then save the measured value file.

5 Menu Bar Elements

5.1.3 File information

The “Documentation of actual recording” window (Fig. 9) allows you to enter your own commentsto describe the measured variables recorded. The text boxes “Project”, “Company”, “Systemcommissioned by” and “System comments” can be used separately. These text boxes require anentry (e.g. *) otherwise a message to this effect will be displayed. When you operate the“Settings...” control a new window will open, where all inverter and tracing data valid at the time ofdata transmission are automatically documented (Fig. 9 and Fig. 10).

01330AENFig. 9: User system comments window

This window is displayed automatically each time before you save a file, prompting you to docu-ment the traced data.

MX_SCOPE 19

Menu Bar Elements 5

All entries made here are saved and printed out together with the measured value file..

01331AENFig. 10: Automatic system documentation by MX_SCOPE

The comments are retained while the program is running until they are overwritten when a new fileis loaded or when they are edited. The comment last entered is saved to the initialization file whenyou exit MX_SCOPE and is available again when the program is restarted.

5.1.4 Upload from inverter

The [Load inverter-data] menu item can only be activated if a communications link with aMOVIDRIVE® inverter is established (=ON-LINE), i.e. MX_SCOPE is not operated OFF-LINE.When you activate this menu item the measurement and parameter data will be read from theMOVIDRIVE® inverter to the PC. First of all, though, different system conditions will be checked. Ifone of the following conditions prevails, the measured data will not be read in, and a message willappear on the screen instead:

• Measured value recording still active.• MX_SCOPE is operating OFF-LINE.• The connected inverter is not a MOVIDRIVE® • Transmission error! Please check the serial link.

Before MX_SCOPE reads in new measured data, you will be asked whether you wish to save or dis-card the previously acquired data, if these have not been saved yet. MX_SCOPE does not recognizewhether the recording was ended correctly with a trigger pulse or aborted with “Trace = stop”, i.e.whether the data in the trace buffer are correct.

At the beginning of the transfer the “Trace data transfer” window will appear indicating the datatransfer progress in per cent. This process can be aborted at any time by pressing the ESCAPE orENTER keys. After MX_SCOPE has read in the buffer completely, the traces are automatically dis-played on the screen.

20 MX_SCOPE

5 Menu Bar Elements

Important:When the trace buffer is read in, all system and parameter values are acquired as well. Therefore,read-in data are only valid if neither the MX_SCOPE system values nor any other parameters werechanged from the moment the data acquisition was triggered to the time the trace buffer was readin.

5.1.5 Print

When you activate the “Print” menu item, the following window will open:

01328AENFig. 11: Printout options of the “Print” window

• Current traces (1 page)graphics printout of the active main window

• MX_SCOPE system dataprintout of system data such as sampling rate, axis address, date/time of recording,etc. and system comment.

Immediately before the hard copy printout the screen will change to monochrome display and atemporary information window will open showing an assignment legend. After printing, the screendisplay will return to normal and the temporary information window will be closed.

Recommendation:For better distinction of the printed traces, activate the trace attribute feature in the “Options/Traceattributes” menu item, which allows you to assign certain markings to a trace for better distinction.

Printer driver:Use the HCSELECT.EXE utility to match MX_SCOPE to the specifics of your printer, in particular fortrace printout. It is not possible to set up the printer from MX_SCOPE. → Sec. 6, MX_SCOPE Files.

The “Start MX_SHELL” menu item calls up the MX_SHELL user interface, exiting MX_SCOPE per-manently. If you haven't saved the acquired data yet, the program will ask you whether you want tosave the data or not. You can specify the call path for MX_SHELL in the “Options/MX_SHELL path”menu item. You may also start MX_SHELL directly from MX_SCOPE. When you exit MX_SCOPEall program settings are saved to the MX_SCOPE.INI initialization file.

5.1.7 Exit

To exit MX_SCOPE select “Exit”. You will be asked whether you want to save the measured data ornot. The active settings are then saved to the initialization file. These settings will be available againwhen MX_SCOPE is restarted.

5.2 Parameters

The [Parameter] menu title comprises all the functions required to set and analyze the measureddata acquisition (tracing).

5.2.1 Scope settings

The [Scope setup] menu item can only be activated if a communications link is established with aMOVIDRIVE® inverter, i.e. MX_SCOPE is not running OFF-LINE. The red header of the [Scopesetup] window (Fig. 12) indicates that in this program section direct communication with the fre-quency inverter takes place. In the absence of a communications link, the controls are disabled,indicated by their greyed-out display. When the inverter is in this condition, standard values aredisplayed which do not represent the actual inverter status.

01329AENFig. 12: Selection of measured variables in the [Scope settings] window

This window allows you to set all the important tracing criteria. At the same time, LED controls onthe panel indicate the current trace status of the MOVIDRIVE® inverter. In addition, you can set thesampling time and select the trigger source and start, abort or stop the tracing process with atrigger event.

Table 5

The various control buttons of this window are explained in Table 5. Operation of the controls issubject to a plausibility check by MX_SCOPE. The setting options therefore depend on the status ofthe measured value tracing. During data acquisition, no trace settings can be made. Controlbuttons of blocked functions are greyed out. When the data acquisition is stopped (Trace = stop) orwhen a trigger event occurs, the trace criteria can be redefined.

Important:When the measured value recording is aborted with the “Trace = stop” command, the trace bufferin the frequency inverter is not written to correctly. MX_SCOPE then has no time reference asregards the measured data, i.e. it cannot detect the earliest measured value. Therefore only use the“Trace = stop” switch control to abort the measured value acquisition. For correct triggering, onlyuse the selected trigger source (external terminal or PC trigger).

5.3 Communications

5.3.1 PC-interface

This menu item allows you to set the COM address of your PC to which the inverter/s is/areconnected.

5.3.2 Connect

This menu item identifies and displays all the inverters which are connected to the PC port. Selectthe inverter you wish to analyze with MX_SCOPE.

5.3.3 Offline

Switches MX_SCOPE on-line/off-line. A check-mark against the inverter in the menu indicates thatthe inverter is off-line. When the inverter is off-line it is not possible to read or set inverter data.

5.3.4 Change address

You may use this menu item to select the inverter you wish to analyze in MX_SCOPE directly. Thesame window as for the [Communications] / [Connect] menu item will open, however withoutinverter identification rerun by the system.

5.3.5 Modem-Connection

This menu item allows you to configure MX_SCOPE for remote diagnosis by modem. When youactivate this function, the PC timeout setting is increased to allow for remote diagnosis even whenthe lines are poor.

5.4 Options

5.4.1 Language (German, English, French)

The “Language” window, in which you can set the language of your choice, will open. Click on the“OK” button to select the desired language and confirm your choice, The system will then checkwhether all the necessary language files are available and switch the program over to the newlanguage. An error message is displayed if the associated language file is not found.

01334AENFig. 13: Language selection window

When you call up MX_SCOPE for the first time, the language selection window is the first to comeup, prompting you to select the language of our choice.

5.4.2 Trace attributes

This function will open the “Trace attributes” window (Fig. 14). Since you may not always have acolour monitor available when you commission a system, it may often prove difficult or evenimpossible to discriminate between the traces. The “Trace attributes” window allows you to assigntrace attributes individualizing the traces. To differentiate the traces you can, for example, markthem with different symbols etc.

01333AENFig. 14: The “Trace attributes” window

The trace attribute feature is also handy when you print out the traces, as printing would usually bein black and white.

MX_SCOPE 25

Menu Bar Elements 5

The table below explains the different attributes and their respective controls.

Table 6

The selected trace attributes are shown in the “Trace attribute assignment” field immediately aftereach change. Only the distance between the marker points is not shown. It must be checkedagainst the actual trace.MX_SCOPE carries out a plausibility check for this feature, too. Trace attributes can only beassigned if the switch control setting is “Trace attributes = ON”. Otherwise all controls will bepassive, i. e. greyed out.

The “Trace attributes = ON” condition where all traces are plotted with the set attributes is indicatedby a checkmark preceding the menu title (“Trace attributes”).

Important:The amount of user memory needed to display the marked traces increases in proportion to thedensity of the marker points, i.e. if you see the warning “Not enough memory....” after setting thetrace attributes, you should decrease the point repeat frequency.

5.4.3 MX_SHELL path

For easier use of MX_SCOPE and MX_SHELL the [File] / [Start MX_SHELL] menu item enables youto call the MX_SHELL user interface directly. MX_SCOPE is then closed permanently andMX_SHELL started.You can specify the call path in which the MX_SHELL.EXE file is located in the [MX_SHELL path...]menu item. When you do this, a file selection box will be opened where you can set the call pathdirectly. If you use the <Select> feature, the system will check whether the file is in the path speci-fied; if it is not, an error message will be displayed.

This setting is stored permanently in the initialization file. The MX_SHELL user interface is called inthe usual way with the [File] / [Start MX_SHELL] menu item.

MX_SCOPE 27

MX_SCOPE Files 6

6 MX_SCOPE Files

For correct operation, MX_SCOPE requires some additional files, which must be located in thesame directory as the MX_SCOPE.EXE file. These files contain important information, which is readin when MX_SCOPE is started and some of it saved again to the files when you exit the program.

Important:All the files referred to below are created automatically (by MX_SCOPE or its system utilities) andtherefore do not require modification.

Initialization file MX_SCOPE.INIThis initialization file contains program settings, which you made when the program was running.The file is saved as an ASCII file when you exit MX_SCOPE or immediately before you startMX_SHELL. When MX_SCOPE is restarted, this file is read in again with the program settings lastmade. If MX_SCOPE cannot find the file or the file is faulty, the default program settings will beused. In this case MX_SCOPE will first display the “Language window” in which to set the languageof your choice. As all settings can be made directly from the program level, there is no need to dis-cuss the individual initialization parameters in detail at this point.

For use in a networked environment this file must be located in a separate directory for each userwith read-write access and also be accessible via the LWPROFILES DOS variable.

Resource files (*.UIR)The resource files contain all the details of the graphics interface and must be located in the samedirectory as MX_SCOPE.EXE. Each language has its own resource file. These are binary files andmust not be modified otherwise stable program operation cannot be ensured.

Text files (*.UIT)The user interface text files contain all the ASCII texts required by MX_SCOPE when running. Eachlanguage must have its own text file. It is not permitted to modify this file as this may causeMX_SCOPE to crash!

ADAPTER.EXE utilityThe ADAPTER.EXE utility allows you to adapt MX_SCOPE to the video adapter installed in your PC.When you select a different video adapter please ensure that the resolution is the same (640x480dots). A different resolution may result in error messages and failure to start MX_SCOPE.

Start the ADAPTER.EXE utility (C:\MX_SCOPE>ADAPTER.EXE <Enter>). The default configurationwill appear on your screen:

Make: IBMType: VGAResolution: 640x480Colors: 16Monitor Type: Colour

28 MX_SCOPE

6 MX_SCOPE Files

This standard VGA mode is supported by almost every VGA compatible video adapter. You maynow select one of three program functions using keys 'y', 'n' or 'q'.

Key: Function:'y' YES: Accepts selected configuration and exits program.'n' NEW: Selects different configuration.'q' QUIT: Exits program without accepting new configuration.Video adapters marked with an asterisk do not work with MX_SCOPE! The configuration selectedwith the ADAPTER.EXE utility is saved to the ADAPTER.PRO file. This file is needed to runMX_SCOPE.

Recommendation:In the particular case of LCD screens (e.g. laptops), a 16-colour display may cause flickering. Forthese applications a 2-colour display is often preferable. To adapt the display, select the followingconfiguration:Make: IBMType: MCGAResolution: 640x480Colours: 2Monitor Type: Monochrome

ADAPTER.PRO video adapter fileThis file contains the details of the system-specific adaptation of your video adapter. It is generatedby the ADAPTER.EXE utility and read by MX_SCOPE. For use in a networked environment this filemust be located in a separate directory for each user with read-write access and also be accessiblevia the LWPROFILES DOS variable.

HCSELECT.EXE utilityThe HCSELECT.EXE utility lets you select a printer driver for use with the “Print” menu item and seta scaling. The settings are stored in the HARD COPY.PRO file. It is not possible to set these varia-bles in MX_SCOPE, you need to call up the HCSELECT.EXE utility to select a printer driver. StartHCSELECT.EXE (C:\MX_SCOPE>HCSELECT.EXE <Enter>) and activate the “Graphics printer” func-tion. You can enter your settings in the “Graphics Printer Configuration” window which comes up.All printer driver settings made with this utility only affect the graphics printout (hard copy) of theMX_SCOPE screen. The default configuration is:

Current Graphics Printer (printer type): HP DESKJET 500DESTINATION (PC port): LPT1Print File (Print to file) Not applicableOrientation: PortraitImage Width: 0.00 (1:1 mode)Image Length: Auto (1:1 mode)Eject Page (Page feed): Yes

MX_SCOPE 29

MX_SCOPE Files 6

00363AENFig. 16: Graphics printer configuration

As all text information is generally routed to LPT1 for printout, the destination port should alwaysremain set to LPT1. The printer type can be selected from a list of approx. 170 printer drivers. Todo this select the function “Select a New Printer”. If your printer is not listed in this printer list,please check your printer manual to find out which printer yours is compatible with and install thisdriver.Printed page orientations are portrait and landscape. Image width and length are specified in inch.The entry 0.00 has a special function, it activates the 1:1 mode, i.e. the best possible print image ofthe selected printer. As all printouts are screen hard copies, the 0.00 setting will provide the bestpossible print quality, however, the printout will only be in A5 format. Below we have listed asample printer parameter setting for a hard copy printout in A4 format.Orientation: LandscapeImage Width: 8.00Image Length: 10.00

Important:MX_SCOPE does not support graphics printout with a GPIB or RS-232 plotter or output to anHPGL plot file as this may cause the program to crash.

HARD COPY.PRO printer fileThe HARD COPY.PRO file contains all the settings of the selected printer driver. It is generated bythe HCSELECT.EXE utility and required by MX_SCOPE for hard copy printout. For use in anetworked environment this file must be located in a separate directory for each user with read-write access and also be accessible via the LWPROFILES DOS variable.For use in a networked environment this file must be located in a separate directory for each userwith read-write access and also be accessible via the LWPROFILES DOS variable.

6 MX_SCOPE Files

PRINTER.DAT fileThis file is used by the HCSELECT.EXE utility and contains a list of all supported printer drivers.It must be located in the current program directory together with the MX_SCOPE.EXE and HCSE-LECT.EXE files.

MX_SCOPE measured value files (*.SCO)These files are MX_SCOPE measured value files. They contain sample traces from the MOVIDRIVE®

inverter. All MX_SCOPE measured value files are saved in ASCII format. They must not be modi-fied, however, as this would result in the loss of data.
