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

DBX92.0
Setting-up mode active
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
Setting-up mode is active for the drive (611D). The setting-up mode is selected using the terminals
on the infeed/regenerative feedback module.
The setting-up mode is required for optimizing the machining process.
The following adaptations and additional functions are possible:
• Drive:
– Reducing the speed setpoint limits
– Reducing the current setpoint limits
• I/RF:
– Disabling the closed-loop DC link voltage control
Signal state 0 or
edge change
1 → 0
Normal operation is active for the drive. The following thus applies:
• The maximum limit values for speed and current setpoint are active
• DC link voltage control is active

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