Speed setpoint (SD43200)

When starting a spindle using a spindle job, then the spindle-specific value entered in the
setting data becomes active as spindle speed:
822
Value Meaning
8 1 A cutting rate is entered as setpoint in the following spindle-specific setting data via
the NC program, synchronized actions or FC18 if the "Constant cutting rate" func‐
tion is active (G96, G961, G962):
SD43202 $SA_SPIND_CONSTCUT_S[<spindle>]
Note
S values that are not programmed cutting rate values are not transferred. e.g.:
● S value for rotation-related dwell time (G4)
0 No cutting rate setpoints are transferred into the setting data.
1 For the master spindle the feedrate type is transferred into the following setting
data:
SD43206 $SA_SPIND_SPEED_TYPE[<spindle>]
0 No feedrate type definitions for the master spindle are transferred into the setting
data.
