Description: Sets the pole position identification technique.
The current magnitudes are limited to the rated power unit values.
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.
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 harmonic
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 SESM w/ 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
Refer to: F07969
Note: For p1980 = 1, 4, 6, 8:
Voltage pulse technique cannot be applied to separately excited synchronous motors (p0300 = 5) and for for
operation with sine-wave output filters (p0230).
For p1980 = 12:
This technique can only be applied for separately excited synchronous motors (SESM) with voltage measurement
(VSM).
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
Recommendation: For 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.
For separately excited synchronous motors, the position identification is realized using the voltage measurement of a
Voltage Sensing Module VSM (p1980 = 12). If there is no VSM then the setting is not possible.
