Only when the inverter is switched off and the
voltage supply is disconnected may the plug be
pulled out or plugged in !
Channel 2 can be equipped with different interfaces. To avoid the connection of a wrong encoder, the installed
interface is indicated in ec.10.

7.11.3.1 Incremental encoder input
In synchronous operation the second incremental encoder serves as input of the master drive. A second posi-
tion encoder can be connected for positioning operation.
