Operation
Perform the axle selection by , , , or button when entering to the
MPG state. When the axle selection signal of MPG interruption of one axis is “1”, then execute the
MPG interruption to this axis by rotating the MPG. The equivalent is identical between the MPG
interruption and MPG feed.
The velocity during the MPG interruption is the sum both in the Auto operation and MPG
interruption movement, and its overlapping speed is controlled within the upper limit speed of the
cutting feed. For example, cutting upper limit is 8000mm/min, if the current feedrate is 2000mm/min,
the MPG interruption speed range is -10000~6000mm/min (“-“ means that the MPG interruption
movement direction is reverse to the feed one).

9.4.2 Affection of Coordinate System from MPG Interruption
Axis moves by MPG interruption, and the actual position of the movement axis changes, the
machine coordinate is renewed instead of the absolute coordinate. Therefore, machine moves after
the MPG interrupts, and the machine coordinate system holds, but the workpiece coordinate system
will offset.
z
Absolute coordinate → Absolute coordinate value will not change due to the MPG
interruption.
z
Relative coordinate → Due to the MPG interruption, Interrupted amount change.
z
Mechanical coordinate → Due to the MPG interruption, interrupted amount change.
When automatically returning the reference point (G28), although the end (reference point) does
not affect by MPG interruption, the intermediate point may generate the offset of interruption value by
the MPG interruption at the workpiece coordinate system
