9 MAJOR POSITIONING CONTROL
9.2.5 4-axis linear interpolation control
In "4-axis linear interpolation control" ("
Da.2
Control system" = ABS linear 4, INC
linear 4), four motors are used to carry out position control in a linear path while
carrying out interpolation for the axis directions set in each axis.

[1] 4-axis linear interpolation control (ABS linear 4)
In the absolute system 4-axis linear control, using an address established by a
machine OPR in the 4-axis coordinate space, a linear interpolation positioning is
carried out from the current stop position (start point address) to the address (end
point address) set in the "

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 control.
