The alarm LED on my MSC series speed control motor unit is flashing 9 times. What could be the cause?

The following are possible causes:

• For some reason, the motor overheated, causing the built-in thermal protector to activate and cut off power to the motor.
• Motor cable is disconnected, broken, or poorly connected.
•  The capacitor is connected incorrectly (short circuited).

Please check the operating environment (high ambient temperature, heavy load, etc.) and the connection status of the motor cable.

Linked below is the MSC manual and page 18 references the alarm codes.
