Product catalog summary

Introduction
This document provides guidance on operating the CD1-pm drive in speed or torque mode via Profibus. It focuses on the control word bit 3 operation and saving the mode selection in the drive EEPROM.

Evolution of Drive Functionalities
The document outlines the evolution of drive functionalities across different firmware releases:

Up to 529.C8 (March 2007): Control word bit 3 has no influence on drive behavior in torque or speed mode, and the mode is not saved in EEPROM.
From 529.D8 (April 2007) to 52A.A8 (September 2008): Control word bit 3 can inhibit or enable operation, but the mode is still not saved in EEPROM.
From 52B.08 (October 2008): Control word bit 3 can enable or inhibit operation based on ASCII command HW or PNU 842 settings. The mode can be saved in EEPROM if bit 9 is set to 1.

Drive Configuration via RS232
For compatibility with earlier firmware versions, the document provides steps to configure the drive using RS232:

Ensure firmware version is 52B.08 or later.
Use an ASCII terminal to read and modify the HW command.
Save the parameter file and execute "Save parameters to EEPROM."

Drive Configuration via Profibus
The document details the configuration of the drive via Profibus using PNU 842, highlighting key bits for functionality:

Bit 4: Analog input reversal for speed limitation.
Bit 6: Enable "Phasing OK" signal.
Bit 7: Enable/Disable analog input for speed limitation.
Bit 8: Control word bit 3 operation.
Bit 9: Speed/Torque mode saving in EEPROM.
Bit 10: Stop with current limit on ENABLE input deactivation.

The configuration can be saved using PNU 729.

INFRANOR ELECTRONICS SAS • Avenue Jean Moulin • B.P. 142 • F-65104 LOURDES Cedex C IN FRAN OR Application note October 16, 2008 CD1-pm PositionersOperation in speed or torque mode via Profibus1) INTRODUCTION This application note is dedicated to the CD1-pm drive operation in speed or torque mode via Profibus. The complete information for the CD1-pm amplifier commissioning and parameterization can be found in the pertaining manuals. This specific information concerns the operation of bit 3 of the control word in speed or torque mode via Profibus, and the saving, in the drive EEPROM, of the speed or torque operating mode selection. The evolution of the drive functionalities in the speed or torque operating mode via Profibus are listed below.

SERVO DRIVES & MOTION CONTROL For the compatibility with the first firmware releases (before version 529.D8) regarding the control word bit 3 operation in torque or speed mode, proceed as follows: - check that the drive firmware version is equal to or greater than version 52B.08, - read the value of the ASCII command HW by using an ASCII terminal, - send the ASCII command HW for setting to 1 bit 8 in the value previously read, - save the drive parameter file (*.par) to be used in the future, - execute the command “Save parameters to EEPROM”. For getting the selection of the torque or speed mode...
