P6-02 Automatic thermal management

Enables automatic thermal management. The inverter automatically reduces the output switching frequency in the event of an excessive heat sink temperature to reduce the risk of an overtemperature fault.

  • 0: Deactivated (PWM fixed - depending on the setting in P2-24)
  • 1: Activated (PWM varies, depending on the following table)
