DBX69.0 - DBX69.2
Controller parameter set switchover (A (checkback signal))
Active parameter set
Application
example(s)
The binary-coded index of the activated parameter set is located in the 3 bits:
• 0 corresponds to the 1st parameter set
• 1 corresponds to the 2nd parameter set
• etc. (max. 6 parameter sets are possible)
Special cases,
errors, ....
Index 0 is returned if the switchover function is disabled with:
MD35590 $MA_PARASET_CHANGE_ENABLE = 0.
In this case, the 1st parameter set is always active.

Lubrication pulse
Edge evaluation: yes Signal(s) updated: cyclic
Edge change
0 → 1
or
1 → 0
As soon as the axis/spindle has covered the traversing distance set in the machine data:
MD33050 $MA_LUBRICATION_DIST (travel distance for lubrication from the PLC)
, the interface signal:
DB31, ...DBX76.0 (lubrication pulse)
is inverted and the lubrication is started.
The position measurement is restarted after each Power On.
Application
example(s)
The lubrication pump for the axis/spindle 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
