The parameter range starts from 750 up to 899, totalizing 150 parameters. The first 50 parameters are predefined by the system or are reserved parameters. The 100 remaining parameters are for general use and may be set by the user. Please find below a description of the parameters defined by the system.

Perhaps some speed, acceleration value, etc. was reset to zero. Attempt to execute some movement Inverter disabled with disabled inverter Incompatible program Check program and install it again. or out of memory This error also occurs when there is limits no program installed in the PLC (PLC powered-up first time). Wrong CRC Transmit it again. Shaft has not been Before an absolut movement , referenced to absolute you must set the machine movement movement to zero position. Fatal Error: after enabled initial Master Reference communication, between master and Fault slave, by any cause has been disabled. Bus off has been detected on the CAN bus due to a high number of transfer Bus off erros. These erros may be caused due to bus problems or due to improper installation.

Note: In fatal erros, E50 and E58, the inverter is disabled and need restart.

CHAPTER

1

INTRODUCTIONThe PLC1 board adds important PLC (Programmable Logical Controller) functions to the CFW-09, enabling the execution of complex linkage program by using the digital board inputs and outputs as well as the digital and analog inputs and outputs of the own inverter which can be accessed by the users program. Among the several available functions we can mention simple contacts and coils up to functions that uses floating point, such as sum, subtraction, multiplication, division, trigonometry, square root functions, etc. Other important functions are the PID blocks, high-pass and low-pass filters, saturation, comparison. All these functions operate with floating point. Besides the functions mentioned above, the PLC1 provides blocks for motor speed and motor position control, that is a trapezoidal-profile positioning and a S-profile positioning, speed reference generation with trapezoidal acceleration ramp, etc. (Note: when positioning functions used, the coupling of an encoder on motor shaft is required). All functions can interact with the user through the 100 programmable parameters that can be acessed directly through the inverter HMI. The texts and user units of the programmable parameters can be customized by the WLP.

ATTENTION!The CFW-09 inverter software version should be the version V2.40 or later.

SAFETY NOTICESThis Manual contains all necessary information for the correct installation and operation of the PLC1 with the CFW-09 Variable Frequency Drive. The PLC1 Manual has been written for qualified personnel with suitable training of technical qualifications to operate this type of equipment Only qualified personnel should plan or implement the installation, startup, operation and maintenance of the CFW-09 and associated equipment. The personnel must follow all safety instructions included in this Manual and/or defined by the local regulations. Failure to comply with these instructions may result in personnel injury and/or equipmrnt damage.

NOTE!In this Manual, qualified personnel are defined as people that are trained to: 1. Install, ground, power up and operate the CFW-09, as well as the PLC1 board, according to this Manual and the local safety procedures; 2. Use the safety equipment according to the local regulations; 3. Give first aid.

DANGER!Always disconnect the supply voltage before touching any electrical component inside the inverter. Many components are charged with high voltages, even after the incoming AC power supply has been disconnected or switched OFF. Wait at least 10 minutes for the total discharge of the power capacitors. Always connect the frame of the equipment to the ground (PE) at the suitable connection point.

ATTENTION!All electronic boards have components that are sensitive to electrostatic discharges. Never touch any of the electrical components or connectors without following proper grounding procedures. If necessary to do so, touch the properly grounded metallic frame or use a suitable ground strap.

NOTE!Read this entire Manual carefully and completely before installing or operating PLC1 board with the CFW-09.

ABOUT THIS MANUAL

This manual describes the basic procedures required for the WLP installation, the creation of projects and provides a general view on the block existing in the PLC1. Chapter 1- Introduction Chapter 2 - Safety Notices; Chapter 3 -General Information; Chapter 4 - General characteristics of the PLC1; Chapter 5 -Description of the Connectors; Chapter 6 - Configuration of the CFW-09 converter with PLC board; Chapter 7 - Installation of the board into the converter; Chapter 8 - Detailed Parameter description; Chapter 9 - WLP blocks; Chapter 10 - WLP; Chapter 11 - RTU - Modbus Protocol in the PLC1. This Manual provides information required for the correct use of the PLC1. As the PLC1 is very flexible, it allows many different operation modes as described in this Manual. As the PLC1 can be applied in several ways, it is impossible to describe here all application possibilities of this board. WEG does not assume any responsibility when the PLC1 is not used according to this manual. No part of this Manual may be reproduced in any form, without written consent of WEG.
