SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Setting for an additional voltage boost when powering-up, however, only for the first acceleration phase.
The voltage boost becomes effective for a positive setpoint increase and disappears as soon as the setpoint has
been reached. The build-up and withdrawal of the voltage boost are smoothed.
Dependency: The current limit p0640 limits the boost.
Refer to: p1300, p1310, p1311, r1315
Notice: The voltage boost results in a higher motor temperature increase.
Note: The voltage boost when accelerating can improve the response to small, positive setpoint changes.
Assigning priorities for the voltage boosts: refer to p1310
Description: Displays the total resulting voltage boost in volt.
r1315 = p1310 + p1311 + p1312
Dependency: Refer to: p1310, p1311, p1312
Description: Sets the starting frequency at which FCC (Flux Current Control) is activated.
Dependency: The correct operating mode must be set (p1300 = 1, 6).
Warning: An excessively low value can result in instability.
Note: For p1333 = 0 Hz, the FCC starting frequency is automatically set to 6 % of the rated motor frequency.
Description: Sets the starting frequency of the slip compensation.
Note: For p1334 = 0, the starting frequency of the slip compensation is automatically set to 6 % of the rated motor fre-
quency.
