Description
Programmable minimum spindle speed limitation
for the master spindle
for spindle number <n>
Programmable maximum spindle speed limitation
for the master spindle
for spindle number <n>
Programmable maximum spindle speed limitation with G96, G961, G97
for the master spindle
for spindle number <n>
Programmable limiting of the configured gear stage dependent maximum speed
Using machine data (MD30455 $MA_MISC_FUNCTION_MASK, bit 6), when program‐
ming in the part program, it can be set as to whether VELOLIM is effective independent of
whether used as spindle or axis (bit 6 = 1) - or is able to be programmed separately for
each operating mode (bit 6 = 0). If they are to be separately effective, then the selection
is made using the name when programming:
● Spindle name S<n> for spindle operating modes
● Axis name, e.g. "C", for axis operation
The correction value refers to:
● Spindles in axis operation (if MD30455 Bit 6 = 0):
To the configured maximum axis velocity (MD32000 $MA_MAX_AX_VELO).
● Spindles in spindle or axis operation (if MD30455 bit 6 = 1):
To the maximum speed of the active gear unit stage
(MD35130 $MA_GEAR_STEP_MAX_VELO_LIMIT[<n>])

Synchronization command for master spindle
The subsequent blocks are not processed until the spindle programmed in a previous NC
block with SPOSA has reached its position (with exact stop fine).
WAITS after M5: Wait until the spindle is stationary.
WAITS after M3/M4: Wait until the spindle reaches its setpoint speed.
Synchronization command for spindle number <n>
Synchronization command for spindle numbers <n> and <m>
Programming of positioning speed (axial feed) for spindle <n> in [deg/min]
With FA[S<n>]=0, the configured value takes effect once more:
MD35300 $MA_SPIND_POSCTRL_VELO
Programming of the axial override value for spindle <n> in [%]
Programming of the axial acceleration capacity for spindle <n> in [%]
