SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Enables thermal adaptation of stator and rotor resistance to reduce torque errors in speed/torque regulation with
speed sensor, or speed errors in speed/torque regulation without speed sensor.
Note: Only stator resistance adaptation is carried out for synchronous motors.
Description: Enters Rs-adaptation controller integral time.
Description: Displays stator resistance adaptation from controller in [%] relative to rated motor resistance.
Note: The rated motor resistance is given by the formula:
Description: Enters Xm-adaptation controller integral time.
Description: Displays main reactance adaptation from controller in [%] relative to rated impedance.
Note: The rated motor resistance is given by the formula:
