OPLC V1040 is used for control Lenze 8400 Highline servo drive. Position of vertically moved linear axis is measured by servo drive encoder and translated to the panel via CANopen. Drive use his own logic for continuous UP - DOWN move changeover. Now only START and STOP command sended to the drive via CANopen. AXIS is connected with 500kBps speed and moved with 0.8m/s max speed. I need to build programmed limit switch (PLS) for control machine valves depending of axis position. It must be switched separately. PLS in UP and DOWN move is different. Now i have 32bit absolute axis position copied to the ML. Problems: 1) how to calculate the axis moving direction by data manipulation with ML; 2) how to STOP axis as much as posible close to the UP or DOWN end position using only ML data and sended via CANopen "stop" command. Any ideas? -
Hello! I'm trying to configure CanOpen communication between Lenze ECSxP Posi&Shaft and Unitronics V1210. I want to set the velocity and the position using PDO1. If I give a high level to the fifteenth bit the control word becomes: First 15 bits are control bits (begin from 0) The velocity value is between 16 to 31 bits it means i can store the value using MI. The velocity is effected in the process data telegram in percent of maximum speed. And the position is between 32 to 61 bits. It is carried out in the process data telegram in resolver increments. I want to give values between 16 and 61 bits It is not possible to use MI to store the position value i need DW, however...inside CANopen Configuration block for RPDO Tx i can use only MI only ML or only DW. Could you give me suggestions how to solve the problem?
