SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Displays the determined moment of inertia of the drive.
After it has been determined, the value is transferred to p0341, p0342.
Dependency: IEC drives (p0100 = 0): unit kg m^2
NEMA drives (p0100 = 1): unit lb ft^2
Refer to: p0341, p0342, p1959
Refer to: F07984
Description: Displays the vibration frequencies determined by the vibration test.
Index: [0] = Frequency low
[1] = Frequency high
Dependency: Refer to: p1959
Refer to: F07985
Description: Sets the pole position identification technique.
Value: 1: Voltage pulsing 1st harmonics
4: Voltage pulsing 2-stage
6: Voltage pulsing 2-stage inverse
10: DC current injection
Dependency: Refer to: p1780
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.
