Detailed Description
2.1 Various interface signals and functions (A2)
DB31, ...
DBX76.0 Lubrication pulse
Edge evaluation: yes
Signal state 1 or If the axis has traversed a distance further than entered in the machine data:
edge change MD33050 $MA_LUBRICATION_DIST (travel distance for lubrication from the PLC)
0 → 1 then the interface signal:
DB31, ...DBX76.0 (lubrication pulse)
is set for one PLC cycle.
Signal state 0 or IS "Lubrication pulse" is automatically reset to 0 after one PLC cycle.
edge change
1 → 0
Application The lubrication pump for the axis can be activated with IS "Lubrication pulse".
example(s) Machine bed lubrication therefore depends on the distance traveled.

DB31, ...
DBX92.0 Setting-up mode active
Edge evaluation: no
Signal state 1 or Setting-up mode is active for the drive (611D). The setting-up mode is selected using the terminals
edge change on the infeed/regenerative feedback module.
0 → 1
The setting-up mode is required for optimizing the machining process.
The following adaptations and additional functions are possible:
•
•
Signal state 0 or Normal operation is active for the drive. The following thus applies:
edge change
•
1 → 0

DB31, ...
DBX92.1 Ramp-function generator fast stop active
Edge evaluation: no
Signal state 1 or PLC receives the signal that the ramp function generator fast stop is active.
edge change
The function has been activated by the interface signal:
0 → 1
DB31, ... DBX20.1 (ramp-function generator fast stop)
The drive is stopped without a ramp function with speed setpoint = 0 and without pulse
suppression.
