P316 DC V-Reg +Limit
Positive threshold for the dead band of the setpoint/actual-value difference
of the U
d
controller
A setpoint/actual-value deviation signal for the DC link voltage is not applied
to the U
d
controller until the deviation of the DC link voltage exceeds
the
value set here.

P318 DC V(set,red)
DC link voltage setpoint with active DC link reduction (i.e. upon request for
U
d
reduction via control word 1, Bit 11= 1 (control word-source selection via
P571) or for internally generated U
d
reduction command in event of
released current-dependent U
d
reduction (P323= 1))
With parameter setting P318 > 100.00 %, the Ud controller
of the E unit or
the E/R unit can be operated at full signal level
with the recovery direction
blocked (P076= xx1).After precharging, this leads to the control angle α=0.

P321 DC CurrThresVred
Current threshold for current-dependent DC link reduction
If I
d
(averaged over 3 current crests) falls below
the value set here, the U
d
setpoint is reduced over a ramp (discharge time P330 active) to the value in
accordance with P318 when current-dependent U
d
reduction (P323=1) is
released.
