6 POSITIONING CONTROL

[Control details]

Control using ABS-3 (Absolute data method)

(1)3 axes linear interpolation from the current stop address (X1, Y1 or Z1) based on the home position to the specified positioning address (X2, Y2, Z2) is executed.

(2)The travel direction is set by the stop address and specified address of each axis.

Example			(Note)

When the current stop address is (1000, 2000, 1000), and the specified address is (4000, 8000, 4000).
