SINAMICS G120 Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
Description: Sets the output limit for the Vdc min controller (DC link undervoltage controller).
Description: Activates/de-activates the automatic sensing of the switch-in level for the Vdc_max controller. When the sensing
function is de-activated, the activation threshold r1282 for the Vdc_max controller is determined from the parame-
terized connection voltage p0210.
Value: 0: Automatic detection inhibited
1: Automatic detection enabled
Description: Sets the time threshold for the Vdc_min controller (kinetic buffering). If this value is exceeded a fault is output; the
required response can be parameterized.
Prerequisite: p1296 = 1.
Notice: If a time threshold has been parameterized, the Vdc_max controller should also be activated (p1280 = 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<p1297 -> F07405
1:
Buff. Vdc until undervo
lt., n<p1297 -> F07405, t>p1295 -> F07406
Note: Re p1296 = 1:
The quick stop ramp entered in p1135 must not be equal to zero, to prevent overcurrent shutdown if F07406 is trig-
gered.
