DBX62.2 Revolutional feed rate active
Edge evaluation: no
Signal state 1 or For programming of G95 (revolutional feed rate) in JOG mode or automatic mode.
edge change
0 → 1
Corresponding to .... SD41100 $SN_JOG_REV_IS_ACTIVE (revolutional feed rate for JOG active)
SD42600 $SC_JOG_FEED_PER_REV_SOURCE
(in the JOG mode revolutional feed rate for geometry axes, on which the frame with rotation acts)
SD43300 $SA_ASSIGN_FEED_PER_REV_SOURCE
(revolutional feed rate for position axes/spindles)
MD32040 $MA_JOG_REV_VELO_RAPID (revolutional feed rate for JOG with rapid traverse
override)
MD32050 $MA_JOG_REV_VELO (revolutional feed rate for JOG mode)
DB31, ...
DBB78 - DBB81 F function for positioning axis
Edge evaluation: no
Signal state 1 or The F value of a positioning axis programmed in the current block is entered in the axis-specific
edge change PLC interface signal.
0 → 1
The assignment between the DB number and machine axis number is established using the axis
name.
The value is retained until it is overwritten by another.
Format: Binary number in real format.
Application Modification of the programmed F value by the PLC, e.g. by overwriting the selected axis-specific
example(s) feed rate override.
