Description: Sets the pole position identification technique.
p1980 = 1, 8: 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.
p1980 = 12: The induced stator voltage is sensed using a VSM and evaluated. This rotor position identification
technique can only be used for separately-excited synchronous motors with incremental encoder.
Value: 1: Voltage pulsing 1st harmonics
4: Voltage pulsing 2-stage
6: Voltage pulsing 2-stage inverse
8: Voltage pulsing 2nd harmonic, inverse
10: DC current injection
12: Rotor position sensing with VSM for FEM with incremental encoder
Dependency: When commissioning a catalog motor, the technique is automatically selected depending on the motor type being
used.
In the simulation mode, the parameter cannot be written into.
Refer to: p0325, p0329, p1272, p1780
Note: Voltage pulse technique (p1980 = 1, 4, 6, 8) cannot be applied to separately-excited synchronous motors (p0300 = 5)
and for for operation with sine-wave output filters (p0230).
The rotor position identification technique (p1980 = 12) cannot be used for permanent-magnet synchronous motors.
Description: Activates the pole position identification routine to determine the commutation angle and to carry out a plausibility
check.
Value: 0: Pole position identification off
1: Pole position identification for commutation
2: Pole position identification for plausibility check
Recommend.: Re p1982 = 1:
This is used for synchronous motors with motor encoder without absolute data.
The information/data regarding the absolute commutation angle is supplied via a track C/D, Hall sensors, an absolute
encoder or from the pole position identification routine.
Re p1982 = 2:
This is used for synchronous motor with motor encoder with absolute data to check this data.
For VECTOR, the following applies:
With p1982 = 2, each time the pulses are enabled it is checked whether the absolute position supplied from the
encoder does not exceed a deviation of 45 degrees to the identified pole wheel position.
With separately-excited synchronous motors (p0300 = 5), pole position identification cannot be selected if an
encoder with position data is used (e.g. SSI encoder).
Dependency: Refer to: p0325, p0329, p1980, r1984, r1985, r1987, p1990
Note: For encoderless operation, the pole position identification routine is selected with p1780.6
