Figure 3-1. SO Drive DIP Switch link locations & Acceleration Cap C25

Motor Selection SO drives are suitable for use with high-performance hybrid or permanent magnet motors having 4, 6 or 8 leads; a 5-lead motor cannot be used with this type of drive. The phase inductance of the motor should ideally lie between 1 mH and 10mH.

The best overall performance will generally be obtained when the unipolar current rating of the motor is between 1 and 1.5 times the current rating of the drive. Therefore the SD2 is best suited to motors in the 1.S-3A range, the SD3 to motors in the 2-4A range and the SOS to motors in the 4-6A range. Select a motor with a current rating at the top of the corresponding range when the maximum high-speed torque is required; whilst there is less torque at low speeds, the reduced winding inductance helps to maintain the torque as speed is increased. The drives can be derated to match motors having a lower current rating, but the associated increase in motor inductance causes a corresponding reduction in high-speed torque.

Motors having 6 leads are best connected in series in order to utilise the whole winding, and in the series mode the current rating of the motor is 70% of the unipolar rating. Therefore try to choose a motor with a unipolar rating of about 3A for the 802, 4A for the 803 or 6A for the 805. Greater flexibility is afforded with a-lead motors since the windings may be connected in series or in parallel. The bipolar rating of the motor relates to parallel connection, but similar characteristics will be obtained from a higher-current motor connected in series. Motors with 4 leads are not suitable for unipolar drives and therefore have a bipolar rating only.

The SO Drive is fitted with four links (see Figure 3-1 for link locations). The following paragraphs describe their functions and optional settings.

CAUTION Remove power from the drive before removing or fitting any links to the drive module or motherboard.

Leave this link fitted.

Do not fit this link.


Link LK3

Link LK4

Acceleration! Deceleration Rate

Adjustment

SO Motherboard

With this link installed, the drive will function in the full-step mode, producing 200 steps/rev. When this link is not installed, the drive will function in the half-step mode, producing 400 steps/rev. The half-step mode is preferred in most applications, the slight torque loss being offset by smoother operation at low speeds; consequently, the drive is shipped from the factory with this link not installed. If you desire full-step operation, remove the link from LKPk and place it in LK3 (see Figure 3-1). LKPk, which stands for link park, is simply a place to store unused links and serves no electrical purpose.

With this link installed, the drive will remain permanent!~' energized and a Shutdown command signal will have no effect on the drive. When link LK4 is not installed, the Shutdown command will affect the drive. The SO drive is factory-configured with this link installed. When not installed, the link can be stored on LKPk, next to LK4 (see Figure 3-1).

The Fast and Slow set speeds are selectable by control lines connected into the motherboard.

The acceleration and deceleration rates between the two set speeds are factory set to 60ms for accelerating from Slow speed to Fast speed, and 30ms for decelerating from Fast speed to Slow speed. These times may be increased by the addition of C25 on the drive module (see Figure 3-1 for location). If a capacitor value of 10llF is fitted the acceleration and deceleration times will increase to 120ms and 60ms respectively. A capacitor of minimum 16V rated voltage should be used. When fitting observe polarity.

It is also possible to obtain a greater increase in the acceleration and deceleration times by replacing C24 with a capacitor value greater than 10)..lF (see Figure 3-1). If C24 is removed a capacitor of minimum 1 OIlF and 16V rated voltage must be fitted in its place.

Links 1 and 2 on the SD Motherboard (see Figure 3-2 for link locations)are fitted in position "b" to use the motherboard mounted preset controls RV1 (FAST ADJ) and RV2 (SLOW ADJ). When external speed controls are required, fit both links in position "a".

You can use the advance rate potentiometers to manually adjust the rate from 40 to 1,000 steps/sec (SLOW pot) or from 400 to 10,000 steps/sec (FAST pot). Refer to Figure 3-2 for the location of the fast and slow advance rate pots.

Turn the pot CW to increase the rate, and CCW to decrease the rate. NOTE: If you set the 'Slow' rate too high you can stall the motor . This function should be used only if the indexer does not need to track the motor's position.

As an alternative to using the switch on the drive, you can reduce the motor current by installing a resistor in the R1 location on the SD Motherboard (see Figure 3-2). The motor current may be set by this resistor according to Table 3-2. R1 may be used to reduce the current level of an SD2 drive to O.2A. The values of current given correspond to the condition when all drive bit switches are in the 'OFF' position. The current level should not be reduced below the lowest figure given for each drive variant.

You can use the advance rate potentiometers to manually adjust the rate from 40 to 1.000 steps/sec (SLOW pot) or from 400 to 10.000 steps/sec (FAST pot). Refer to Figure 3-2 for the location of the fast and slow rate advance pots.

Turn the pot CW to increase the rate, and CCW to decrease the rate. NOTE: If you set the rate too high you can stall the motor. This function should be used only if the indexer does not need to track the motor's position.

Refer to the System Connections section in this chapter for instructions to wire optional remote advance rate pots from the indexer connector.

As an alternative to using the switch on the drive, you can reduce the motor current by installing a resistor in the RS location on the back of the SOC Motherboard (see Figure 3-3). The values of current given correspond to the condition when all the drive bit switches are 'OFF'. This resistor may be used to reduce the S02 drive motor current O.2A. The current level should not be reduced below the lowest figures given for each drive type. Table 3-3 provides typical resistor values. Remember that the actual current wiff depend on motor inductance .

Table 33. SDC Motherboard RS Resistor Values for Setting Current

The SD Drive system should be operated in temperatures from OC to 50C (32F to 122DF) and al a relative humidity between 0 and 95% (non-condensing). Make sure the system is stored in temperatures within the range from -40C to 85C (-40F to 185D F). Refer to the manufacturer's environmental specifications for the maximum motor case temperature when it is in operation.

You should install the SD Drive system in an enclosure to protect it against atmospheric contaminants such as oil, moisture, and din. Ideally, you should install the system in a rack cabinet In the USA, the National Electrical Manufacturers Association (NEMA) has established standards that define the degree of protection that electrical enclosures provide. The enclosure should conform to NEMA Type 12 standards if the intended environment is industrial and contains airborne contaminants. Proper layout of components IS required to ensure sufficient cooling of equipment within the enclosure.

You should give special attention to the environment and location In which you will operate your SO Drive system. Consider atmospheric contamination and temperature around the drive before you install and operate your SO Drive system.

Your SO Drive system is normally shipped with the drive(s) pre-installed In the standard 19"-long 5.Z-hlgh rack.

Motor Mounting

Transformer Mounting

System Connections


The SO Drive system will operate most hybrid stepper motors. Molars should be mounted USing flange bolts and centred by the pilot on the front face. Foot-mount configurations are a less desirable alternative because the torque of the motor is not evenly distributed around the motor case. Any radial load on the motor shaft is multiplied by a much longer lever arm when a foot mount IS used rather than a face flange.

WARNING Improper mounting can compromise system performance and jeopardize personal safety.

The transformer models used with the SD Drive system (models T0116, TOlt9, and T0120) may be mounted in the cabinet or, If you are not using a cabinet, close to the rack system you are uSing. Ensure that the transformer is located where It does not have excessively long leads and does not interfere with the SO Drive system operation and electrical connections. Transformer dimensions and weights are provided in Chapter 6, Hardware Reference.

WARNING Do not mount the transformer where it is likely to be touched by personnel. Touching the wiring studs while the transformer is energized can inflict a lethal electrical shock.

If you have set all the SO Drive functions, you are now ready to perform the final wiring for your system. Pinouts on the drive's 32-way edge connector and on both of the types of motherboard usable are illustrated in Chapter 4, Hardware Reference .

Refer to Chapter 2, Getting Started, for instructions on the following system connections:

Motor Indexer Transformer

WARNING Ensure that AC power is disconnected before you perform any wiring. NEVER disconnect the motor with power applied to the drive.


Wiring Guidelines

Connecting via a Motherboard

Factory Settings

Proper grounding of electrical equipment is essential to ensure the safety of personnel. You can reduce the effects of electrical noise due to electromagnetic interference (EMI) by grounding. All Digiplan equipment should be properly grounded. A good source of information on grounding requirements is the National Electrical Code published by the National Fire Protection Association of Boston, Massachusetts.

In general, all components and enclosures must be connected to earth ground to provide a low impedance path for ground fault or noise-induced currents. All earth ground connections must be continuous and permanent. Digiplan recommends using a central earth stud mounted on the rack end-plate or close to it. AC ground, the transformer shield, the rack OV bus, and the enclosure metalwork should all be connected to this stud. In particular, you should connect the rack OV bus with a t 8AWG (1 mm') cable kept as short as possible.

The SO Drive system is normally shipped with the drive(s) pre-installed in the appropriate SR rack.

CAUTION Ensure the AC power is disconnected before attempting to perform any system connections. Never disconnect the motor with power on; this will damage the drive and the motor connector contacts. Follow the steps described below to complete the basic configuration of your system.

Rack-mount SO Drive functions are factory-set to provide optimum system performance and safe operation. You do not need to alter these settings to accommodate the preliminary system operation and testing discussed in this chapter. Normally, these factory settings, with the exception of motor current, will satisfy the complete system operating requirements. Chapter 3, Installation, discusses optional drive settings you can use for your particular application. The basic drive operating conditions are factory set as follows:

Drive current is set at maximum (2A for S02, 3A for SD3 and 4.5A for S05) Drive resolution is set at 400 steps/rev

Motor Connections


If you purchased a Digiplan stepper motor with the SO Drive system, please refer to the Digiplan Motor Manual for connection details. Tables 3-4 and 3-5 show connection details for a range of proprietary stepper motors.

After you determine the motor's wiring configuration, connect the motor leads to connector TS1 on the motherboard.

CAUTION Be sure to properly connect the motor to the SD Drive motherboard. Incorrect connections could damage the drive or the motor.

Table 3-7. SOC Motherboard Indexer Connector (SKT1) Pinouts The PL 1 (SOC M01herboard) and SKT1 (SO Motherboard) connectors provide optional connections for the drive control signals (see Figure 3-8).

These inputs are for using non-TTL Digiplan indexers, clock cards (MC1, Be?, Re9, etc.). or an indexer that has output characteristics that differ from TTL indexers.

If you are D.Q1 using a Digiplan indexer with standard Digiplan cables, it may be easier for you to use connector PL 1. The electrical specifications for this connector are provided in Chapter 4, Hardware Reference. The inputs on PL 1/SKT1 are not compatible with Olglplan or Compumotor TIL indexers.

':'I0TE: Caution must be used since these inputs are not optically Isolated.

+24 Volts (Pin 1)

Fault (Pin 2)

This terminal may be used as an output to provide +24V from the SO Drive to external control circuitry. Current drawn must be limited to a total of 250mA.

This is an output signal which goes high in the event of an overload fault. It is driven by an open-collector transistor and should be pulled up by an external resistor when the signal is required. The resistor should be returned to a voltage no higher than +25V, and should not allow more than 15mA to flow when the output is low.

When a fault occurs, the drive will de-energise until the shutdown signal is cycled or the power is cycled after the fault has cleared .

You can establish a visual fault verification by installing an LED as illustrated in Figure 3-9. Here the LED will be lit unless there is a fault.

Figure 3-9. Fault Output Example

This is an output signal that goes low when the drive translator is in its primary state. This occurs every 8 motor steps in the halt-step mode. The drive always powers up In the zero-phase state. Ths signal is used in conjunction With an auto-homing circuit. Electrical parameters are the same as those 01 the Faull output.

Taking this input terminal low (connecting it to the OV terminal) Will reverse the direction of motor rotation. The direction should only be changed when the molor is stationary or running within the start/stop speed range. The input is not TTL compatible.

A low-going transition on this input terminal causes the motor to advance one step. The input should remain low for not less than 10!!s. The maximum step pulse frequency is 20kHz in the half-step mode. The input is not TTL compatible.

CAUTION Do not stop the clock while it is running above the start/stop speed; this will cause the motor to de-synchronise.

This input terminal enables the motor to be Shut down (de-energized) so that it may be rotated slowly by hand without SWitching the system off. You must connect this input terminal to the OV terminal in order to energize the motor. NOTE: If link LK4 is installed. the shutdown Input has no effect and the drive remains energised at all times except in the event of a fault

The input is not TTL compatible.

Use this terminal as the common return pain! for the indexer signals.

11 you set links LKI. LK2, and LK3 on the SDC Drive motherboard to position B, the ADJUST COMMON, FAST ADJUST, and SLOW ADJUST signals are diverted to the 25-pin indexer connector. Pins 6 and 7 are the slow and fast adjust pins, and pin 19 is the adjust common. USing these pins, you can wire remote jog potentiometers (pots) as Illustrated in Figure 3-10.

Using the SLOW. FAST. and ov signals from the 25-pin connector. you can wire remote slowlfast jog switches (see Figure 3-10). When you close the switch from the slow input (pin 12) or the fast input (pin 13) to OV (pin 25), the motor runs at the rate set with the corresponding pot. The slow range is 40 to 1,000 steps/sec. The fast range is 400 to 10,000 steps/sec.

Using the 8-pin PL 1 connector, you can also wire a remote direction switch using the DIRECTION (pin 5) and ov (pin 8) signals (see Figure 3-10). When the direction switch IS grounded to OV,the motor moves in the opposite direction.

NOTE: The jog switches should be used ~ Ii the indexer does.D.Q1 need to track the motor's position.

Figure 3-10 also shows the corresponding external connections on the SO motherboard. Note that links LKI and LK2 should be transferred to pOSition 'a' to isolate the board-mounted rate adjust controls when external pots are used.

SHUTDOWN+ & SHUTDOWN-

Remote Advance Rate Inputs

Indexer Inputs (compatible with most Diglplan and Compumotor indexers) are transmitted via the Indexer connector on the SDC Motherboard. These inputs are optically isolated within the SD Drive and are intended to be driven differentially from 5V logic levels. Figure 4-3 represents the input circuits.

A pulse on these inputs (i.e. pin 1 positive with respect to pin 14) causes the motor to step on a hlgh-to-Iow transition. The pulse should remain high for at least lOllS. Consult your indexer user guide for instructions on how to change the output pulse width

These inputs (pins 2 and 15) controllhe direction of the molar shaft rotation. Changing the level of these inputs changes the direction in which the shaft moves.

These differential inputs (pins 16 and 17) are used to energize and de-energize (shut down) the motor. To remotely shutdown the dnve, you must first remove the energize link (LK4) on the drive. When the shutdown+ input is taken high and shutdown- is low, the drive is shut down and the motor shaft may be rotated slowly by hand. NOTE: Back-driving the motor may stress the drive and could cause failure. Taking the shutdown+ input high whilst shutdown- is low resets a fault condition, and the drive is re-energized when the input returns low.

If you set links LKI, LK2, and LK3 on the SD Drive motherboard to position B, the Adjust Common, Fast Adjust, and Slow Adjust signals are diverted to the 25-pin indexer connector (see Figure 4-2 for pinouts). Using these pins, you can wire remote jog potentiometers (pots) as demonstrated in Chapter 3.

CHAPTER 4. HARDWARE REFERENCE 41

As demonstrated in Chapter 3, you can also use the Slow, Fast, and OV signals from the 25-pin connector to wire remote slow/fast switches (see pinouts in Figure 4-2). When you close the switch on the slow input (pin 12) orthe fast input (pin 13) to the OV input (pin 25), the motor runs at the rate set with the corresponding pot The slow range is 40 to 1,000 steps/sec. The fast range is 400 to 10,000 steps/sec. NOTE: This function should be used ~ if the indexer does nm need to track the motor's position.

PL1 on the back of the SDC Motherboard IS an 8-pm ramp connector providing connections for the four drive control signals (see Figure 4-2). If you are!lQl using a Digiplan or Compumotor indexer with standard cables, it may be easier for you to use the ramp connector (PL 1). Refer to Table 5-4 for electrical specifications. The inputs on Pl1 are compatible with Digiplan rack-mounting indexer cards and indexers with open collector outputs only_

NOTE: Caution must be used, since these mputs are nm optically isolated and are therefore more noise-sensitive than the inputs on the 25-pin indexer connector (SKTt). Figure 4-3 shows methods of connecting signals to the SDC Motherboard via SKT 1. The equivalent devices in alternative logic families to those quoted are not necessarily compatible. Methods other than those shown may be used but they should comply With the requirements shown in Table 4-3.

These circuits are designed for maximum noise immunity and especially where long leads are necessary and interierence fields exist, the ideal Input arrangement is a differential line driver with twisted pair cabling to the inputs. Cable length should always be kept as short as possible.

Input Circuit B could be used as an alternative to the line driver cirCUit but poorer noise immunity would result.

Input Circuit C would operate satisfactorily where the cable length is short and interierence fields are minimal.

PL 1 allows signal connections to the drive by-passing the opto-isolators. Figure 4-4 shows a method of coupling TTL signals to the drive and indicates the circuit arrangements at the PL1 Interiace Note that the signals at PL 1 are themselves not TTL compatible .

Description

Sig nal Descriptions . SO Motherboard

1. External Reference Input

(VREFEXT)

2. +24VDC Out

The use of an SO Motherboard simplifies the installation of the drive since all external connections may be made without the need for soldering. Opta-isolation of the main control signals is NOT provided with this motherboard but it incorporates preset controls for setting the speed of the internal oscillator without the need for external components. Links 1 and 2 on the motherboard are are fitted in position "bl! to use the preset controls, When external speed controls are required for the on-board oscillator, fit the links in position "a",

15. Internal Clock Output

Transformer Wiring

This is the output of the internal oscll!ator which will normally be connected to the clock input of the drive (terminal 7). The output consists of low-going pulses approximately 25).18 wide.

Depending on your application, the SO Drive system is equipped with one of the following transformer models. The transformer used in your system depends on your application.

Model T0116 - 100VA Model T0119 - 300VA Model T0120 - 450VA

Input power to and output power from the transformer are AC. The drive receives AC power from the transformer via TB2 on the motherboard. If your application requires different supply voltages, use Table 5-6 to select the appropriate primary wiring configuration.

CAUTION Always wire the transformer first, then check the secondary output voltages on open-circuit BEFORE you connect the transformer to the SD Drive motherboard. Note: Be sure to connect the AC ground (GND) to SCN (Earth Ground).

Chapter 5. MAINTENANCE & TROUBLESHOOTING

Chapter Objectives

Maintenance

Motor

Drive

The information in this chapter will enable you to do the following:

Maintain the system's components to ensure smooth, efficient operation Isolate and resolve system hardware and software problems

Routine maintenance is not necessary, but occasional checking of the following pOints is recommended .

You should inspect the motor to ensure that no bolts or couplings have become loose during operation. This will prevent minor defects from developing into more serious problems.

The ball bearings used in most stepper motors are permanently lubricated and do not require any maintenance.

You should inspect the motor cable or leads periodically for signs of wear. You should not apply excessive tensile force to the cable or bend it beyond a one-inch radius of curvature during normal operation. Tighten all cable connectors.

Check that the drive heatsink is free of particles and has a free flow of air over its entire surtaC9. Enclosures must be connected to earth ground through a grounding electrode conductor to provide a low-impedance path for ground-fault or noise-induced currents. Check the security of the ground connections.

Troubleshooting This section discusses methods to identify and resolve problems that may occur with your SO Drive System.

Problem Isolation When your system does not function properly (or as you expect it to operate), the first thing that you must do is identify and isolate the problem.

Isolate each system component and ensure that each one functions properly when it is run independently. You may have to remove system components and re-install them to detect the problem.
