Over-current at Power Running (ECM)

What does 1 mean?

An over-current condition has occurred in the DC link during power running operation of the motor. This indicates excessive current draw, potentially due to motor load or amplifier issues.

• Excessive current drawn by the motor during normal acceleration or running phases.
• Motor is overloaded beyond its rated capacity.
• Mechanical issue causing increased motor torque requirement (e.g., binding, excessive friction).
• Incorrect motor tuning or acceleration profile settings (e.g., P1-03, P1-04).
• Voltage drop to the motor causing increased current draw.

Click steps to track your progress.

1. 1

   Check the motor load during power running operation. Reduce if excessive.

2. 2

   Inspect the servo amplifier for any over-current related alarms.

3. 3

   Verify the DC link current sensors for proper operation.
