9 MAJOR POSITIONING CONTROL

[2] 4-axis linear interpolation control (INC linear 4)

Operation chart

In the incremental system 4-axis linear interpolation control, using an address
established by a machine OPR in the 4-axis coordinate plane, a linear interpolation
positioning is carried out from the current stop position (start point address) to a

position at the end of the movement amount set in the " Da.6 Positioning

address/movement amount". The movement direction depends on the sign (+ or -)
of the movement amount.

Restrictions

An error will occur and the positioning will not start in the following cases. The
machine will immediately stop if the error is detected during a positioning
operation.

If the movement amount of each axis exceeds "1073741824 (=2

30

)" when "0:

Composite speed" is set in " Pr.20 Interpolation speed designation method"
... The "Outside linear movement amount range error (error code: 504)" occurs

at a positioning start.

(The maximum movement amount that can be set in " Da.6 Positioning

address/movement amount" is "1073741824 (=2

30

)".)
