SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Sets the offset voltage in the beta direction; this compensates the offset voltages of the drive converter/inverter at
low speeds. The value is valid for the rated (nominal) pulse frequency of the power unit.
Note: The value is pre-set during the rotating measurement.
Description: Displays the internal status signals of the motor model:
Index 0: Changeover ramp between current and voltage models
Index 1: Changeover ramp for model tracking (encoderless induction motors only)
Index 2: Changeover ramp for zero frequency range (encoderless induction motors only)
Index: [0] = Changeover ramp motor model
[1] = Changeover ramp model tracking
[2] = Changeover ramp zero frequency encoderless ASM
[3...6] = Reserved
Description: Sets the configuration for the adaptation circuit of the motor model.
Induction motor (ASM): Rs, Lh, and offset compensation.
Dependency: In U/f characteristic operating mode only bit 7 is relevant.
For active motor model feedback (see p1784), the Lh adaptation is internally deactivated automatically.
Note: ASM: Induction motor
When selecting the compensation of the valve interlocking via Rs (bit 7), the compensation in the gating unit is de-
activated and is instead taken into account in the motor model.
In order that the correction values of the Rs and Lh adaptation (selected using bit 0 ... bit 1) are correctly accepted
when changing over the drive data set, a dedicated motor number must be entered into p0826 for each different
motor.
