2.2 List of parameters
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 feedback (only encoderless induction motors)
Index 2: Changeover ramp for zero frequency range (only encoderless induction motors)
Index 3: Transition ramp actual speed from speed setpoint to model value (SESM without encoder)
Index 4: Speed controller enable (SESM without encoder)
Index 5: Transition ramp between current and voltage models (SESM without encoder)
Index 6: Transition ramp for EMF deviation at PLL input (PMSM without encoder)
Index: [0] = Changeover ramp motor model
[1] = Changeover ramp model tracking
[2] = Changeover ramp zero frequency encoderless ASM
[3] = Changeover ramp actual speed SESM without encoder
[4] = Enable speed controller SESM without encoder
[5] = Changeover ramp motor model SESM without encoder
[6] = Changeover ramp motor model PMSM without encoder
Note: Indices 3 through 5 are only relevant in the case of encoderless control of separately excited synchronous motors.
Description: Induction motor (ASM):
Displays the difference between the motor model flux angle and the transformation angle.
Permanent-magnet synchronous motor (PMSM):
Displays the angular difference between motor model and encoder.
Dependency: A setting for smoothing the display can be made using p1754.
