Val.
1 Intermediate circuit DC undervoltage *
1 Intermediate circuit DC overvoltage *
1 Torque reference minimum limit is active. The limit is
defined by parameter
1 Torque reference maximum limit is active. The limit is
defined by parameter
1 An inverter current limit is active. The limit is identified by
bits 8...11.
1 For permanent magnet motor only: Load angle limit is
active, ie, the motor cannot produce more torque.
1 For asynchronous motor only: Motor pull-out limit is active,
ie, the motor cannot produce more torque.
1 Bit 4 = 0: Input current is limited by main circuit thermal
limit. Bit 4 = 1: Output current is limited by main circuit
thermal limit.
1 Inverter output current limit is active. **
1 Maximum inverter output current limit is active. The limit is
defined by parameter
