268 List Manual, 04/2018, A5E33838102
Description: Sets the maximum flux setpoint to measure the saturation characteristic.
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.
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
Dependency: Refer to: p1780
Refer to: F07969
Note: Voltage pulse technique (p1980 = 1, 4, 8) cannot be applied for operation with sine-wave output filters (p0230).
Description: Display and BICO output for the diagnostics information of the pole position identification (polID)
Dependency: Refer to: p0325, p0329, p1980
Note: The data of p1992 are updated in a 4 ms cycle.
Fast changes of the encoder status word bits can be better investigated using p7830 and following.
