Description: Sets the pole position identification technique.
p1980 = 1: The current magnitude is set using P0329.
p1980 = 4, 6: The current magnitude of the first measurement section is set using p0325, the second using p0329.
p1980 = 10: The rated motor current is impressed to align.
The current magnitudes are limited to the rated power unit values.
Value: 1: Voltage pulsing 1st harmonics
4: Voltage pulsing 2-stage
6: Voltage pulsing 2-stage inverse
10: DC current injection
Dependency: When commissioning a catalog motor, the technique is automatically selected depending on the motor type being
used.
Refer to: p0325, p0329, p1780
Refer to: F07969
Note: Voltage pulse technique (p1980 = 1, 4) cannot be applied to operation with sine-wave output filters (p0230).
Description: Displays the angular difference between the actual electrical commutation angle and the angle determined by the
pole position identification.
Dependency: Refer to: p0325, p0329, p1980, r1985, r1987
Note: When the pole position identification routine is executed several times, the spread of the measured values can be
determined using this value. At the same position, the spread should be less than 2 degrees electrical.
Description: Displays the saturation characteristic of the pole position identification routine (saturation technique).
Displays the current characteristic of the pole position identification routine (elasticity technique).
Dependency: Refer to: p0325, p0329, p1980, r1984, r1987
Note: PolID: Pole position identification
Regarding the saturation technique:
The values for the characteristic of the last saturation-based pole position identification routine are output every 1
ms in order to record signals (e.g. trace).
