2.6.8.6 Gear stage change
Operational sequences
The gear stage change requires physical movements from the NCK in order to select a new
gear.
A gear stage change is not required in the SERUPRO operation and is performed as follows:
Some gears can only be changed when controlled by the NC, since either the axis must
oscillate or a certain position must be approached beforehand.
The gear stage change can be suppressed selectively for DryRun, program test, and
SERUPRO using bits 0 to 2 in MD35035 $MA_SPIND_FUNCTION_MASK.
The gear stage change must then be performed in REPOS; this will work even if the axis
involved is to be in "speed control mode" at the target block. In other cases, the automatic
gear stage change is denied with an alarm if, for example, the axis was involved in a
transformation or coupling between the gear stage change and the target block.

2.6.8.7 Superimposed motion
Only SERUPRO
If "overlaid movements" are used, only the block search via program test (SERUPRO) can
be used, since the overlaid movements are interpolated accordingly in the main run. This
applies in particular to $AA_OFF.
Velocity profile instead of maximum axis velocity
During Program test, a velocity profile must be used, which allows "superimposed
movements" to be interpolated during the main run. It is thus not possible to interpolate at
the maximum axis velocity.
The axis velocity is set in "Dry run feedrate" mode using
SD42100 $SC_DRY_RUN_FEED.
The velocity of the SERUPRO operation is selected using
MD22600 $MC_SERUPRO_SPEED_MODE.
