Description
Master spindle is the spindle specified in the following machine data:
MD20090 $MC_SPIND_DEF_MASTER_SPIND (position of deletion of the master spin‐
dle in the channel)
The spindle with the number <n> is the master spindle
(may differ from the initial setting:
MD20090 $MC_SPIND_DEF_MASTER_SPIND).
The master spindle must be defined for the following functions:
● G95:
● G96 S.../G961

without entering the spindle number
The current master spindle setting can be retained via RESET / part program end and part
program start. The setting is done via the machine data:
● MD20110 $MC_RESET_MODE_MASK
● MD20112 $MC_START_MODE_MASK
