SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Notice: If a time threshold has been parameterized, the Vdc_max controller should also be activated (p1240 = 3) so that the
drive does not shut down with overvoltage when Vdc_min control is exited (due to the time violation) and in the
event of fault response OFF3. It is also possible to increase the OFF3 ramp-down time p1135.
Description: Sets the response for the Vdc_min controller (kinetic buffering).
Value: 0: Buffer Vdc until undervoltage, n<p1257 -> F07405
1: Buff. Vdc until undervolt., n<p1257 -> F07405, t>p1255 -> F07406
Dependency: Refer to: F07405, F07406
Description: Sets the speed threshold for the Vdc-min controller (kinetic buffering).
If this value is exceeded a fault is output; the required response can be parameterized .
Description: Displays the actual output of the Vdc controller (DC link voltage controller)
Note: The regenerative power limit p1531 is used for vector control to pre-control the Vdc_max controller. The lower the
power limit is set, the lower the correction signals of the controller when the voltage limit is reached.
Description: Sets the configuration for the bypass function.
Value: 0: Bypass de-activated
3: Bypass without synchronization
Note: When the converter is switched on, the state of the bridging contactor is evaluated. If the automatic restart is active
(p1210 = 4) and both an ON command (r0054.0 = 1) and the bypass signal (p1266 = 1, configuration p1267.0 = 1)
are still present during power-up, the converter goes into "ready for operation and bypass" state (r0899.0 = 1 and
r0046.25 = 1) after power-up, and the motor continues to run directly on the line.
The "bypass" function can only be switched off again (p1260 = 0) if the bypass is not active or the bypass function
has a fault.
The flying restart function must be activated (p1200).
