4.6 Pin Assignment for Encoder/Resolver OC7M0
The Plug detect feature, which monitors that pins 11 and 13 are connected, detects the unintentional disconnection of the plug connector.
NOTICE
If the Plug detect connection is missing while the interface is activated (parameter 9.4.1 Interface configuration "Disabled"), the drive generates a fault.
- The fault is generated only when switching to closed-loop operation, not when selecting an encoder. - The plug connector is delivered without a connection between pin 11 and 13.
