Inverter: IPM alarm (OH) (N axis)

Hva betyr A. ?

An Intelligent Power Module (IPM) overheat alarm has occurred for the N-axis. This indicates the IPM for the N-axis is operating at an excessively high temperature. This typically results from the motor being used under harsh conditions (e.g., heavy load) or a high ambient temperature around the SVM.

• The motor is being used under a harsh condition.
• The ambient temperature is high.
• SVM failure.

1. 1

   Verify the motor load for the N-axis is within its rated specifications.

2. 2

   Measure the ambient temperature around the SVM.

3. 3

   Verify adequate airflow to the SVM's heat sink and cooling components for the N-axis.
