Feeds (V1)
2.16.1
Signals to channel (DB21, ...)
DB21, ...
DBX0.6
Activate dry run feed
Edge evaluation: yes
Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The dry run feed rate defined using the setting data:
SD42100 $SC_DRY_RUN_FEED
is used instead of the programmed feed (for
G01
,
G02
,
G03
) if the dry run feed rate is greater than
that programmed.
The dry run feed rate is effective after the reset state.
This interface signal is evaluated at NC start when the channel is in the "reset" state.
The dry run feed can be activated from the PLC or operator panel.
When selected from the operator panel front, the PLC interface signal:
DB21, ... DBX24.6 (dry run feed selected)
is set and transferred from the PLC basic program to the interface signal:
DB21, ... DBX0.6 (activate dry run feed).
When selected using the PLC, the IS "activate dry run feed" should be set from the PLC user
program.
Signal state 0 or
edge change
1 → 0
The programmed feed is used.
Effective after the reset state.
Application
example(s)
Testing a workpiece program with an increased feed rate.
Special cases,
errors, ......
If the signal changes to "0" within a
G33
block, the programmed feed is not activated until the end of
the block is reached, since an NC stop was not triggered.
