Control via I/O interface

5.3.1

General

If the controller is activated via the I/O interface [X2], only the record selection operating mode is avail­
able. The operating modes of direct mode and jogging are not possible.
Record 0 is reserved for homing. The records 1 ... 31 configured with the FCT are selected as desired by
the higher-order controller via the binary coded inputs DIN1 ... DIN5.
The other inputs and outputs serve to start the selected record or to output status messages, for ex­
ample.
5.3.2

Communication

Communication takes place via the I/O interface [X2].
Note
Make sure to use PNP I/Os
