5. OPERATIONAL FUNCTIONS
5.4 Linear interpolation
5.4.1 Summary
Linear interpolation operation has interpolation control performed for the axes set up as a group. This system
enables a maximum of 4 axis interpolation control. When the feed speed and position data are defined in the
point table and the fast start operation signal (FST) is input, all of the axes setup in the group perform linear
interpolation operation. If linear interpolation operation is started prior to completion of home position return
(home position return request (ZREQ) is ON), a home position return not complete error (operation alarm 90,
detail 01) occurs upon starting operation and the operation stops.
Afterwards, the fast start operation signal (FST) is input on a primary axis and other axes are referred to as
auxiliary axes.

The group setting is set using the linear interpolation group (parameter
No.0260). If the group number is set to 0, the axis becomes an independent
axis, making it so linear interpolation operation can not be performed. The
number of groups that can be defined differs with the control cycle and the
maximum number of groups is 8.

The fast start operation signal (FST) is only to be input on a primary axis.
