SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Sets maximum modulation index.
Note: P1803 = 100 % : Limit for over-control (for ideal inverter without switching delay).
For vector control the modulation limit will be reduced automatically with 4 %.
If a LC-filter is selected (P0230 = 3 or (P0230 = 4 and P234 > 0)), the max. modulation index is set to 100 % if it is
greater than 100 %.
If an internal output filter is installed the modulation depth is limited to 100 % (p0230 = 3 and p1803 <= 100 %).
Description: Configures Vdc filtering and compensation.
Description: Changes direction of motor rotation without changing setpoint polarity.
Values: 0: Forward
1: Reverse the Motor
Dependency: If positive and negative revolution is enabled, frequency setpoint is directly used.
If both positive and negative revolution are disabled, reference value is set to zero.
Note: See P1000 (select frequency setpoint)
Description: Corrects on-state voltage of the IGBTs.
