SIMODRIVE 611U 515: Power Module Temperature Exceeded

What 515 means

The power module heatsink is too hot. The drive warns first and shuts down about 20 seconds later.

Symptoms

Trips after running a while under load, or in a hot cabinet.

Is it repairable?

Yes: fans are replaced and power modules repaired and tested.

Common causes

  • Failed or clogged module fan
  • Blocked airflow
  • High cabinet temperature
  • Too much load for the module size

Safe checks

  1. 1Check the fan and airflow through the module
  2. 2Clean dust
  3. 3Measure the cabinet temperature

Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.

Reviewed by AutomIQ repair technicians. Code and name from the SIMODRIVE 611 universal Function Manual.
