2.2 List of parameters
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.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Note: The value is pre-set during the rotating measurement.
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.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
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 for induction motors without encoder)
Index 2: Changeover ramp for zero frequency range (only for induction motors 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 induction motor without encoder
[3] = Reserved
[4] = Reserved
[5] = Reserved
[6] = Changeover ramp motor model PMSM without encoder
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Note: ASM: induction motor
PMSM: permanent-magnet synchronous motor
Description: Displays the difference between the motor model flux angle and the transformation angle.
