Motor Controller Error
(Hardware Current Trip)
Keep error on screen until OK button pressed. End workout.
Condition
Error sent by Motor Controller when it detects an over current condition (i.e. current limit threshold exceeded. Also
called - "Controller Fault 1 Trip". Applies to motorized equipment only.
Cause
• Issue with encoder on Power mills (run encoder test to validate).
• Excessive user weight/load
• Bad motor controller
• Bad motor
• Shorted motor cable
• Power module
• Debris entrapment
Remedy
• Run encoder test
• Intermittent connections between motor and motor controller board can cause hardware current trips. This trip is
fast acting and an intermittent cable / connector / poor terminal crimp can cause large changes in current draw
• Check motor power cable and connector terminals for damage, unseat and re-seat motor connection to control
board
• Check motor phase resistance and ensure isolation between phases and case
