PSMR Excessive Short-Term Regenerative Power

Was bedeutet 8 ?

This alarm occurs in the Power Supply Module with Regenerative (PSMR) when the system experiences excessive short-term regenerative power. This condition indicates that the energy generated by the motor during deceleration or braking exceeds the capacity of the regenerative resistance or circuit. It can lead to overvoltage on the DC link or damage to the regenerative components.

• Insufficient regenerative resistance specification for the application.
• Failure within the regenerative circuit components.

1. 1

   Review the specification of the regenerative resistance to ensure it is appropriately sized for the application's regenerative power requirements.

2. 2

   If the regenerative circuit is abnormal after resistance review, replace the PSMR unit.
