Line contactor control
This function can be used to control an external line contactor. Opening and closing the line
contactor can be monitored by evaluating the feedback contact in the line contactor.
The line contactor can be controlled with the following drive objects:
● Bit r0863.1
● Bit r0863.1
Note
Further information on the line connection can be found in the manuals:
Note
Possible pre-charging faults with very long switching times
An external line contactor / external circuit breaker with very long switching times can result
in a pre-charging fault (F30027 "Power unit: Time monitoring for DC link pre-charging",
F6000 "Infeed: Pre-charging monitoring time expired" ), when the switch is controlled via
r0863 "CO/BO: Drive coupling status/control word" bit 1 "control contactor" and p860 "BI:
Line contactor, feedback signal".
The monitoring of the pre-charging starts with r0863.1 =1 and does not take into account a
delayed closing (and thus a delayed feedback signal p0860).
For line contactors / circuit breakers with a very long delay time, control them externally (for
example using a PLC) before the ON1 command for the drive. In this way, the required line
voltage is applied before the start of pre-charging at the inverter.
