Par.
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.
RDS parameter
PNU=13CHex; Type=O2; Scaling: 1Hex
P317 DC V-Reg -Limit
Negative 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 drops below the
value set
RDS parameter
PNU=13DHex; Type=I2; Scaling: 1Hex
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.
RDS parameter
PNU=13EHex; Type=O2; Scaling: 1Hex
P319 DC V(set,red)Hys
Hysteresis for Ud < Ud(set,red)
(message "Ud reduced")
RDS parameter
PNU=13FHex; Type=O2; Scaling: 1Hex
P320 Smooth Load Amps
Smoothing time for feedforward load current injection
RDS parameter
PNU=140Hex; Type=O2; Scaling: 1Hex
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.
RDS parameter
PNU=141Hex; Type=O2; Scaling: 1Hex
P322 DC CurrHyst.Vred
Hysteresis for current-dependent DC link voltage reduction
If I d (averaged over 3 current crests) exceeds the sum of P321 and the
value set here, the U d setpoint increases over a ramp (precharge time P329
active) to the value 1.35 * U line,feed when current-dependent U d reduction
is released (P323=1).
RDS parameter
PNU=142Hex; Type=O2; Scaling: 1Hex
