Auto Restart
Auto restart after power outage
If the power fails at one of the terminals U1/L1, V1/L2, W1/L3, 1U2/1T1,
1V2/1T2 1W2/1T3, X9.1 and X9.2, or if the voltage is not within the
permissible tolerance range and
the DC link voltage has dropped beneath
the P074
*
1.35
*
P071 threshold, the S/F unit responds as follows::
0 Auto restart inhibited
No automatic restart; the corresponding fault message (F003,
F004, F005, F007, F009 or F010) is triggered.
1 Acknowledgment following power outage
The rectifier/regenerating unit enters status
o
008 (switch-on
inhibit) or
o
009 (switch on/off from the I/O keys of the PMU). On
power recovery, a new ON command must be given to enable
the DC link to re-charge. The inverter is not
automatically
restarted by the WEA (auto restart) function.
2 Restart following power recovery and pre-charging of the DC
link
During the power outage, the controllers and firing pulses of the
PZD R/R are inhibited. The rectifier/regenerating unit enters
status
o
010. On recovery of the voltage, the DC link is charged
again as quickly as possible (see Section 4.3.10.1).
Important: The necessary external measures must be taken to guarantee
safety on an automatic restart!

P409 Contactor Delay
Closing delay of the line contactor
Closing of the line contactor is delayed by the time set here with respect to
the "Switch on" command.
This parameter can be used to implement time grading when energizing the
line contactors of several drive units in order to prevent the inrush currents
of the autotransformers for regenerative mode overloading a supply
transformer.
