2.2 List of parameters
Description: Sets the starting behavior for I2t monitoring of the motor.
Value: 2: Start I2t with zero
12: Start I2t with saved value
Note: If value = 12:
For motor I2t monitoring, when switching off, the model temperature is saved in a non-volatile fashion. When
switching on, the saved value is taken into account in the model calculation. As a consequence, the UL508C
specification is fulfilled.
Description: Sets the inverter stability limit for the firing angle of the armature converter in single-phase operation.
Dependency: Refer to: r53190
Note: The status of the Alpha W limit is shown in r53190.8.
Description: Setting of the correction angle for current-dependent offset of the Alpha W limit.
Description: Sets the rectifier stability limit for the firing angle of the armature converter.
Dependency: Refer to: r53190
Note: The status of the Alpha G limit is shown in r53190.7.
