Description
Spindle position control ON
for the master spindle
for spindle number <n>
for spindle numbers <n> and <m>
Spindle position control OFF, activate speed control mode
for the master spindle
for spindle number <n>
for spindle numbers <n> and <m>
Revolutional feedrate for spindle <n> ON, derived from the master spindle
Revolutional feedrate for spindle <n> ON, derived from spindle <m>
The revolutional feedrate value must be specified with FA[S<m>].
Revolutional feedrate for spindle <n> OFF
Rotary axis C (spindle in axis mode) travels to the position 30 degrees at a speed of 3600
degrees/min = 10 rpm
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>])

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.
