Detailed Description
2.5 Programming
Spindlespecific functions
MD35035
Machine data:
MD35035 $MA_SPIND_FUNCTION_MASK
defines spindle-specific functions from the part programs, FC18 and synchronized actions as
follows:
No gear step change with DryRun, program testing and SERUPRO.
Bit 0 = 1
Bit 1 = 1
Bit 2 = 1
Acceptance of programmed speed and cutting rate including settings.
Bit 4 = 1
Bit 5 = 1
Bit 8 = 1
Spindle override is also actively influenced during zero marker search with M19, SPOS, or SPOSA.
Bit 12 = 1

Gear step change for blocks with M40, M41 to M45 or via FC18 and
synchronized actions are suppressed with DryRun.
Gear step change for blocks with M40, M41 to M45 or via FC18 and
synchronized actions are suppressed with Program Test and SERUPRO.
Gear step change for programmed gear step is performed after deselection of
functions DryRun and SERUPRO.
The programmed speed including speed specifications are accepted in setting
data:
SD43200 $SA_SPIND_S.
through FC18 and synchronized actions.
The content of setting data:
SD43200 $SA_SPIND_S
serves as the setpoint speed in JOG mode.
You can use the JOG keys to operate the spindle at the speed defined in
SD43200.
If the content is zero, other JOG speed specifications are active
(see setting data SD41200 $SN_JOGSPIND_SET_VELO).
The programmed cutting speed including specifications for FC18 and
synchronized actions are accepted in SD43202 $SA_SPIND_S.
Spindle override is effective during zero marker search with M19, SPOS, or
SPOSA.
