SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
Description: Sets the DC braking time (as fault response).
Dependency: Refer to: p1230, p1231, p1232, p1234, r1239
Description: Sets the starting speed for DC braking.
If the actual speed falls below this threshold, then DC braking is activated.
Dependency: Refer to: p1230, p1231, p1232, p1233, r1239
Description: Status word of the DC braking.
Dependency: Refer to: p1231, p1232, p1233, p1234
Note: Re bit 12, 13:
Only effective for p1231 = 14.
Description: Sets the controller configuration of the DC link voltage (Vdc controller) in the closed-loop control mode. For U/f con-
trol: see p1280.
Value: 0: Inhib Vdc ctrl
1: Enable Vdc_max controller
3: Enable Vdc_min controller and Vdc_max controller
Dependency: Refer to: p1245
Refer to: A07400, A07401, A07402, F07405, F07406
Notice: An excessively high value in p1245 can possibly negatively influence the normal operation of the drive.
