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)
Index: [0] = Changeover ramp motor model
[1] = Changeover ramp model tracking
[2] = Changeover ramp zero frequency encoderless ASM
[3] = Changeover ramp actual speed encoderless FEM
[4] = Enable speed controller encoderless FEM
[5] = Changeover ramp motor model encoderless FEM
[6] = Changeover ramp motor model encoderless PESM
Note: Indices 3 through 5 are only relevant in the case of encoderless control of separately excited synchronous motors.
Description: Displays the difference between the motor model flux angle and the transformation angle.
Dependency: A setting for smoothing the display can be made using p1754.
Description: Sets the configuration for the adaptation circuit of the motor model.
Induction motor (ASM): Rs, Lh, and offset compensation.
Permanent magnet synchronous motor (PEM): kT
Note: ASM: Induction motor
PEM: Permanent magnet synchronous motor
When selecting the compensation of the valve interlocking via Rs (bit 7), the compensation in the gating unit is
deactivated and is instead taken into account in the motor model.
In order that the correction values of the Rs, Lh and kT adaptation (selected using Bit 0 ... Bit 2) are correctly
accepted when changing over the drive data set, a dedicated motor number must be entered into p0826 for each
different motor.
