Hello! We are using a ControlLogix 1756-L72 PLC with two identical servo motors running separate conveyor belts. The machine this is on runs nearly 24/5 and then sits idle (but powered on) over the weekends. The last couple of Mondays, one of the servos would not start running again when starting the conveyors back up. The servo is an AB MPL-A1530U-EJ72AA using a Kinetix 350 drive (2097-V31PR2-LM). While it was in this state, I logged on to the PLC and viewed the Axis Properties and there were no faults/alarms present. We are using a "Motion Axis Jog" command to run the servo. The requested position is updating and the requested velocity is correct, but the actual position is not moving and the actual velocity is 0. The standstill bit is on as well. I tried to do a Motion Servo Off / Motion Servo On as well as a Motion Axis Fault Reset, but nothing seemed to work and no faults/alarms were popping up. The second identical servo will run normally. The only way to get the first servo working properly is to do a full power down / power up of the machine, then it starts right up like nothing was wrong. Nothing is showing up on the Kinetix drive either and all lights are normal. Any ideas as to what is causing this / ideas of things to check next time this occurs? Thanks for your help!!!
