11.6 Block change
Since path and positioning axes are interpolated separately, they reach their programmed end
positions at different instants in time. If path and positioning axes are programmed in a block
together, then the block change behavior depends on the programmable type of positioning
axes.
Type 1: Block-related positioning axis
Properties:
● The block change is performed as soon as all path and positioning axes have reached
their respective programmed end-of-motion criterion:
– Path axes: G601, G602, G603
– Positioning axes: FINEA, COARSA, IPOENDA
● Programming the positioning axis: POS[<axis>]

Description
No revolutional feed rate selected
The revolutional feed rate is derived from the round axis/spindle with the machine axis index
specified here.
The revolutional feed rate is derived from the master spindle of the channel in which the
axis/spindle is active.
The revolutional feed rate is derived from the rotary axis/spindle with the machine axis index
0.
The revolutional feed rate is derived from the master spindle of the channel in which the
axis/spindle is active. No revolutional feed rate is selected if the master spindle is at a
standstill.
