there are other detail faults.
61
Motor Controller
Current Sensor Fault
Disable Lifting and Driving
Motor Controller Current Sensor Fault: Drive or Lift
Motor may be overheating. Let the lift cool down. If
that does not help, cycle power to reset the Motor
controller. If the problem persists, check the wiring
and if OK, try replacing the Motor Controller.
62
Motor Controller
Hardware Failsafe
Fault
Disable Lifting and Driving
Motor Controller Hardware Failsafe Fault: Cycle
power. If that does not resolve the issue check for
noise sources. If still needed, try replacing the
Motor Controller.
63
Motor Controller
Motor Short Fault
Disable All Motion
Motor Controller Motor Short Fault: Check wiring
first then cycle power. If needed replace controller.
64
Motor Controller SRO
