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

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.
