apply to be able to make adaptations.
To be able to use various spindle functions, such as
S Revolutional feed (G95)
S Tapping with compensation chuck (G63)
S Thread cutting (G33)
S Dwell time in spindle revolutions (G4 S...)
in a channel, a master spindle has to be defined in the corresponding channel:
S MD20090: SPIND_DEF_MASTER_SPIND (master spindle initial setting in
channel)
In machine data
S MD35000: SPIND_ASSIGN_TO_MACHAX (spindle number)
the defined spindle number of the spindle of the channel is entered, which will
be the master spindle.
Machine data
S MD35040: SPIND_ACTIVE_AFTER_RESET (spindle active after reset)
defines whether the spindle is to remain active beyond
S Reset (IS: DB21,... DBX7.7)
S End of program (M02/M30).
To cancel spindle movements, an independent spindle reset is required:
S IS: DB31,... DBX2.2 (spindle reset)
