Default mode setting

Machine data
The default setting of the spindle mode allows configuration of the basic spindle setting
following Power On, NC-START and RESET using machine data:
MD35020 $MA_SPIND_DEFAULT_MODE
and
MD35030 $MA_SPIND_DEFAULT_ACT_MASK
.

If the spindle is to be stopped from direction of rotation (M3 or M4) with orientation, or is to
be re-oriented from standstill (M5), then the positioning mode is selected with SPOS,
SPOSA or M19.
If spindle orientation is to be terminated, M3, M4 or M5 is used to change to control mode.
The last programmed spindle speed (S-value) is activated.
If the orientation of the spindle is to be terminated, M41 to M45 can be used to switch to
oscillation mode. When the gear change is complete, the last programmed spindle speed
( -value) and M5 (Control mode) are reactivated.

If a spindle was stopped with orientation, the assigned axis name is used to program a
change to axis mode. The gear step is retained.
Switching from open-loop control mode to axis mode can be also achieved by
programming of M70. In this case, a rotating spindle is decelerated in the same way as for
M5, position control activated and the zero parameter set selected.
To terminate axis mode, M3, M4 or M5 can be used to change to control mode. The last
programmed spindle speed (S-value) is activated.
To terminate axis mode, M41 to M45 can be used to change to oscillation mode (only if
the programmed gear step is not the same as the actual gear step). When the gear
change is complete, the last programmed spindle speed (S-value) and M5 (Control mode)
are reactivated.
