2.2 List of parameters
r1773[0...1]

Motor model slip speed / MotMod slip

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL, FEM
Min
- [rpm]
Description: Displays estimated (speed) signals of the motor model.
r1773[0]: Displays the estimated (mechanical) slip of the motor model.
r1773[1]: Displays the estimated input speed of the motor model.
Index: [0] = Slip speed estimated
[1] = Speed estimated
p1774[0...n] Motor model offset voltage compensation alpha / MotMod offs comp A
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PEM, REL, FEM
Min
-5.000 [V]
Description: Sets the offset voltage in the alpha 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.
p1775[0...n]

Motor model offset voltage compensation beta / MotMod offs comp B

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PEM, REL, FEM
Min
-5.000 [V]
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.
r1776[0...6]

Motor model status signals / MotMod status sig

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
-
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 3: Transition ramp actual speed from speed setpoint to model value (encoderless FEM)
Index 4: Speed controller enable (encoderless FEM)
Index 5: Transition ramp between current and voltage models (encoderless FEM)
Index 6: Transition ramp for EMF deviation at PLL input (encoderless PESM)
