Supplementary conditions

If a container axis in axis mode or as a positioning spindle (POSA, SPOSA) traverses, the axis

container rotates only after reaching the programmed end position.

● A container axis active as a spindle continues to rotate during an axis container rotation.

● The control type of a spindle (speed / position control) refers to the associated machine

axis. The set control type "moves" with the machine axis when an axis container rotates.

● For commands that refer to the master spindle of the channel, a machine axis with the

corresponding spindle number must exist in the channel at the time of execution of the

MD35000 $MA_SPIND_ASSIGN_TO_MACHAX[ <axis>] == number of the master spindle

It is the sole responsibility of the user / machine manufacturer to ensure for spindles as

container axes that an appropriate machine axis must still exist in the channel after an axis

container rotation for the master spindle.

Work offsets

It is the sole responsibility of the user / machine manufacturer to ensure that after an axis

container rotation the effective work offsets in the channel are adapted to the changed machine

axis assignments.

Continuous-path mode

If continuous-path mode is active in the channel and an axis container rotation is performed,

a subsequent programming of a container axis interrupts the continuous-path mode. The

interruption also occurs even when the container axis not a path axis.
