2.2 List of parameters
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
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
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 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)
