Description
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 is used for the electrical isolation of the DC link for the energy supply network.
The line contactor can be controlled using the following drive objects:
● Via bit r0863.1 of drive object INFEED
● Via bit r0863.1 of drive object SERVO/VECTOR
Note
For more information on the line connection, see the Equipment Manuals.
