DB21, ...
DBX24.6
Dry run feed rate selected
Edge evaluation: No
Signal(s) updated: Cyclically
Signal state 1 or
edge change
0 → 1
Dry run feed rate is selected.
Instead of the programmed feed rate, the dry run feed rate entered in setting data:
SD42100 $SC_DRY_RUN_FEED
is active.
When activated from the operator panel, the dry run feed signal is automatically entered in the PLC
interface and transmitted by the PLC basic program to the PLC interface signal:
DB21, ... DBX0.6 (active dry run feed).
Signal state 0 or
edge change
1 → 0
Dry run feed rate is not selected.
The programmed feed rate is active.
Corresponding to .... DB21, ... DBX0.6 (activate dry run feed)
SD42100 $SC_DRY_RUN_FEED (dry run feed rate)
DB21, ...
DBX25.3
Feed rate override selected for rapid traverse
Edge evaluation: No
Signal(s) updated: Cyclically
Signal state 1 or
edge change
0 → 1
The feed rate override switch should also be active as rapid traverse override switch.
Override values above 100% are limited to the maximum value for 100% rapid traverse override.
The interface signal:
DB21, ... DBX25.3 (feed rate override for rapid traverse selected)
is automatically entered into the PLC interface from the operator panel
and transferred from the PLC basic program to the PLC interface signal:
DB21, ... DBX6.6 (rapid traverse override active).
Further, the interface signal:
DB21, ... DBB4 (feed rate override)
is copied from the PLC basic program to the interface signal:
DB21, ... DBB5 (rapid traverse override).
Signal state 0 or
edge change
1 → 0
The feed rate override switch should not be activated as rapid traverse override switch.
Application
example(s)
The signal is used when no separate rapid traverse override switch is available.
