• Response to NC and mode-group stop:
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
.
M function output
Auxiliary function
M19
is output to the VDI interface by:
M[n]=19
always output to the IS
SPOS [n]
Output of
M19
to the IS with MD setting:
MD20850 $MC_SPOS_TO_VDI = 1
SPOSA[n]
Output of
M19
to the IS with MD setting:
MD20850 $MC_SPOS_TO_VDI = 1
If
M19
is programmed, auxiliary function
M [n]=19
is always output to the interface.
For
SPOS
and
SPOSAM19
is 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]
where n = spindle number
FA[Sn]=0
the configured speed is active
The speed is specified in [degrees/min].
