6.2.1 FC INC_MOD
The FC INC_MOD is the main block for programming the FM 351. When
the FC is called you immediately set the incremental operating mode. This is
independent of the assignment of the individual parameters.
The FM 351 signals the acceptance of the operating mode with the set pa-
rameter INC_MD_A.
You then operate the incremental mode via the individual parameters.
With the FC you have the following functions available:
Setting the incremental operating mode.
Controlling the incremental operating mode.
Reading the check-back signals (e.g. actual value). The read data is saved
in the channel DB by the FC.

The FC INC_MOD works in combination with the channel DB. When calling
you indicate the number with the parameter DB_NO.
Take note of the following requirements which must be satisfied for calling
the FC INC_MOD:
Take into account the generally applicable requirements of Chapter 6.2.
Before you can start an incremental approach, you must supply the
FM 351 with the appropriate incremental dimensions.
