Over-current of Discharge Current (ECM)

What does 4 mean?

An over-current condition has occurred in the discharge current path from the Capacitor Modules of the ECM. This indicates a problem with the discharge circuit, potentially during emergency stop or an internal fault.

• Excessive discharge current from the motor exceeds ECM's rated limit.
• Short circuit within the motor windings or drive components.
• Sudden heavy load applied to the motor during operation.
• Incorrect motor model or parameters configured in the drive (e.g., P1-01 to P1-09).
• Motor encoder signal failure causing incorrect speed feedback.

Click steps to track your progress.

1. 1

   Inspect the wiring and connections from the Capacitor Modules to the discharge circuit.

2. 2

   Verify the operation of the Resistor Module, which is used for discharging.

3. 3

   Check the Capacitor Modules for any signs of damage or internal shorts.
