Setting via FC18 synchronized actions
If the constant cutting rate is set via FC18, the setting of bit 6 in byte to in the "Signals to
concurring positioning axes" area determines how the speed value (bytes 8...11) is
interpreted.
In the case of setting via synchronized actions, the feedrate type will determine how the S
value is interpreted, analogously to the part program.
Reading from part program and synchronized actions
The programmed cutting rate value can be determined both in the part program and in
synchronized actions by reading system variables:
$P_CONSTCUT_S
and
$AC_CONSTCUT_S.
The programmed cutting rate value can also be read via the OPI interface.
System variables
RV: Defined range of values of the two new system variables.
Description NCK variable
Last constant cutting rate programmed
RV = {0, DBL_Max}
$P_CONSTRUCT_S[n]
Current constant cutting rate
RV = {0, DBL_Max}
$AC_CONSTRUCT_S[n]
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 Gear step change for blocks with M40, M41 to M45 or via FC18 and
synchronized actions are suppressed with DryRun.
Bit 1 = 1 Gear step change for blocks with M40, M41 to M45 or via FC18 and
synchronized actions are suppressed with Program Test and SERUPRO.
Bit 2 = 1 Gear step change for programmed gear step is performed after deselection of
functions DryRun and SERUPRO.
Acceptance of programmed speed and cutting rate including settings.
Bit 4 = 1 The programmed speed including speed specifications are accepted in setting
data:
SD43200 $SA_SPIND_S.
through FC18 and synchronized actions.
