Description
Spindle positioning for the master spindle
Spindle positioning for spindle number <n>
The block change is executed immediately. Spindle positioning continues, regardless of
further part program processing, until the spindle has reached its position.
The direction of motion is retained for positioning while in motion and the position ap‐
proached. When positioning from standstill, the position is approached via the shortest
path.
The position is always approached with negative direction of motion. If necessary, the
direction of motion is inverted prior to positioning.
The position is always approached with positive direction of motion.
If necessary, the direction of motion is inverted prior to positioning.
The travel path is specified. The direction of travel is determined from the sign in front of
the travel path. If the spindle is in motion, the direction of travel is inverted as necessary
to allow traversing in the programmed direction.
If the zero mark is crossed during traversing, the spindle is automatically synchronized
with the zero mark if no reference is available or if a new one has been requested via an
interface signal.
Positioning the master spindle to the position in SD43240
Positioning spindle number <n> to the position in SD43240
The block change is only performed when the spindle is in position.
Bring spindle to standstill and activate position control, select zero parameter set, activate
axis mode

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
