P330 Discharge Time
DC link discharge time
An even parameter value causes abrupt lowering. With effect from software
version 4.5, an odd parameter value causes the Ud setpoint to ramp down
with Ud reduction controlled by STW1, bit11 (see Section 4.3.1.1 and
4.3.10.2).
With the command OFF1 and current-dependent Ud reduction, P330 is
active in all cases.
