SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Displays the effective modulator mode.
Value: 1: Flat top modulation (FLB)
2: Space vector modulation (SVM)
3: Edge modulation from 28 Hz; 23:3
4: Edge modulation from 28 Hz; 19:1
5: Edge modulation from 60 Hz; 17:3
6: Edge modulation from 60 Hz; 17:1
7: Edge modulation from 100 Hz; 9:2
8: Edge modulation from 100 Hz; 9:1
9: Optimized pulse pattern
Description: Sets the configuration for the modulator.
Notice: Bit 1 = 1 can only be set under a pulse inhibit and for r0192.14 = 1.
Note: Re bit 00 = 0:
Voltage limitation from the minimum of the DC link voltage (lower ripple in the output current, reduced output volt-
age).
Re bit 00 = 1:
Voltage limitation from averaged DC link voltage (higher output voltage with increased ripple in the output current).
The selection is only valid if the DC link compensation is not performed in the Control Unit (bit 1 = 0).
Re bit 01 = 0:
DC link voltage compensation in the modulator.
Re bit 01 = 1:
DC link voltage compensation in the current control.
Description: Sets the phase sequence reversal for the motor without setpoint change.
If the motor does not rotate in the required direction, then the output phase sequence can be reversed using this
parameter. This means that the direction of the motor is reversed without the setpoint being changed.
Value: 0: OFF
1: ON
Note: This setting can only be changed when the pulses are inhibited.
