Detailed Description
2.6 Spindle monitoring
Basic logic functions: Spindles (S1)
86 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
2.6.2 Axis/spindle stationary (n < n min)
Spindle monitoring with stationary axis/spindle
Only if the axis/spindle is stationary, i.e., the actual spindle speed falls below a specifiable
value in machie data:
MD36060 $MA_STANDSTILL_VELO_TOL (maximum velocity/speed "Axis/spindle
stationary")
and no longer generates any setpoints, is it possible to perform certain functions on the
machine, such as tool change, open machine doors, path feed enable, etc.
If the spindle is stationary,
• NC/PLC IS:
DB31, ... DBX61.4 axis/spindle stationary)
is set to 1.
• The next machining block is released
and machine data:
MD35510 $MA_SPIND_STOPPED_AT_IPO_START
is set to 0.
Exception:
MD35510 $MA_SPIND_STOPPED_AT_IPO_START =1
Path interpolation is not influenced, the traveled path axis is not stopped.
Monitoring is effective in all spindle modes and in axis mode.
