Signals To Axis/Spindle (Digital Drives) - Siemens SINUMERIK 828D Function Manual

DB31, ... DBX76.0 (lubrication pulse)
Following a control POWER ON/RESET, the signal status is 0 (FALSE).
The "lubrication pulse" is inverted (edge change), as soon as the machine axis has covered the parameterized
traversing distance for lubrication:
MD33050 $MA_LUBRICATION_DIST (distance for lubrication by PLC)
