Motor I2t monitoring starting behavior / Mot I2t strt behav

DC_CTRL Can be changed: U, T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
2
Description: Sets the starting behavior for I2t monitoring of the motor.
Value: 2:
12:
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.
