Line contactor control

☐
This function allows an external line contactor to be controlled. The closing and opening of
the line contactor can be monitored by evaluating the feedback contact of the line contactor.
The line contactor can be controlled with the following drive objects via r0863.1:
● For the infeed drive object
● For the SERVO and VECTOR drive objects
Parameterizing the switch-on delay and the monitoring time
This dialog shows the enable interconnection of the line contactor.
1. Enter in the "Power unit / switch-on delay" (p0862) field, the switch-on delay.
2. Enter in the "Line contactor / monitoring time" (p0861) field, the monitoring time of the line
contactor.
The monitoring time starts for each switching operation of the line contactor (r0863.1). If
no feedback from the line contactor is detected within this time, a message is issued.
3. Connect the binector input for "Line contactor feedback" (p0860).
Use for activated monitoring (BI: p0860 not equal r0863.1), the BO: r0863.1 signal of the
dedicated drive object for controlling the line contactor.
4. Connect the binector output for "Control contactor (r0963.1)".
