Siemens SINUMERIK 840D sl Function Manual page 1629

• Response to NC and mode-group stop:
M function output
Auxiliary function M19 is output to the VDI interface by:
M[n]=19
SPOS [n]
SPOSA[n]
If M19 is programmed, auxiliary function M [n]=19 is always output to the interface.
For SPOS and SPOSAM19is output depending on machine data:
MD20850 $MC_SPOS_TO_VDI
to the IS.
Feed
The positioning speed is configured using machine data:
MD35300 $MA_SPIND_POSCTRL_VELO
and can be modified by programming or by synchronized actions:
FA[Sn]
FA[Sn]=0
The speed is specified in [degrees/min].
Basic logic functions: Spindles (S1)
Function Manual, 11/2006, 6FC5397-0BP10-2BA0
If an NC or mode-group stop is triggered during WAITS, the wait operation is resumed
after the NC start with all the above conditions.
Note
In particular when using spindles across different channels, care should be taken when
programming not to start WAITS too early in one channel, i.e., at a time when the spindle
in the other channel is still rotating at its "old" speed.
In such cases, the "Spindle in setpoint range" signal is activated and WAITS is *stopped
too soon.
To prevent this happening, it is strongly recommended to set a WAITM before WAITS.
always output to the IS
Output of M19 to the IS with MD setting:
MD20850 $MC_SPOS_TO_VDI = 1
Output of M19 to the IS with MD setting:
MD20850 $MC_SPOS_TO_VDI = 1
where n = spindle number
the configured speed is active
