the Drive or Motor

Drive components overheating is probably the most common reason for drive failure. Be certain you follow the manufacturer's recommended mounting and ventilation practices. Over time, contaminants can build on the surface of internal drive components and restrict them from properly dispersing their heat.

Motor failure due to overheating is also very common. Most motor overheating problems can be traced back to misapplication, like overloading the motor. Make sure your application isn’t using an undersized motor. Other overload causes include: locked rotors, motor misalignment, and stressful environmental conditions.

Verify feedback device wiring is connected properly and the configuration of the drive, its connected motor, and any feedback device (armature, tachometer, hall sensor) has not changed. If the problem persists, swap suspect feedback device with a good unit to troubleshoot.
