MVP 2021 kratmel Posted January 27, 2020 MVP 2021 Report Share Posted January 27, 2020 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? Quote Link to comment Share on other sites More sharing options...
