: Always set
: Set as required (Read "–" when not required.)
: Setting not possible
– : Setting not required.
(This is an irrelevant item, so the set value will be ignored. If the value is the default value or within the setting range, there is no problem.)
: Two control systems are available: the absolute (ABS) system and incremental (INC) system.

The items
Da.1 to Da.10 , Da.20 to Da.22 are checked at the following timings:
