There are three main LED fault signals that the DM556 and DM442 drivers exhibit. There is a red and green LED. The red LED will show the fault signals.
The fault signals are:
- Over-Current: If there is continuous current that is above 16 amps, the Red LED will flash every three seconds. Over-current could be related to: a short in the motor coils, or two of the wires of the motor are shorted; of the motor wires/coil is shorted to ground.
- Over-voltage: If the power supply output to the driver exceeds a voltage of 52 volts, the red LED will flash twice every three seconds.
- Phase Error: Is the motor wires are not connect, or they are connected incorrectly, the red LED will flash four times every three seconds.
