Troubleshooting

Overview		The system troubleshooting procedures involve observing the status of the LED’s.
		The tables in this section provide information related to the indications provided by
		these devices.

LED	Color	Status	Comments
ON	Green	Power is applied.	Not a failure.

Step	Green	Incoming Steps, Direction CW	Not a failure.
	Yellow	Incoming Steps, Direction CCW	Not a failure.
	Red
Bus	Green
	Yellow	Continuous on=overvoltage condition	Verify input voltage is proper. Not a failure.
		Flashing = Regen condition	Regen operation is not a failure.
	Red	Undervoltage condition	Verify input voltage is proper
FLT	Green
	Yellow	Interlock condition.	Verify motor connections.
	Red	Motor short.	Replace motor.
