Limits of the interpolation control
Limits are provided on the interpolation control that can be executed and speed ([Pr.20] Interpolation speed specification
method) that can be set, depending on the settings in [Pr.1] Unit setting of the reference axis and interpolation axis. (For
example, the circular interpolation control cannot be performed if the unit of the reference axis and that of the interpolation
axis differ.)
The following table shows the limits of the interpolation control and speed specification.
: Setting possible,
: Setting not possible,
: No interpolation axis
*1 The units of mm and inch can be mixed.
*2 If Composite speed is set for the 2-axis speed control, 3-axis speed control, 4-axis speed control, and 4-axis linear interpolation control
and the positioning is started, Interpolation mode error (Error code: 199AH) occurs and the positioning will not start.
*3 If Reference axis speed is set for the 2-axis circular interpolation control and 3-axis helical interpolation control and the positioning is
started, Interpolation mode error (Error code: 199BH) occurs and the positioning will not start.
*4 If the units are different or if mm and inch are mixed, use the unit set to the reference axis for the unit of the speed being controlled.
*5 The unit of degree cannot be set. If the circular interpolation control or 3-axis helical interpolation control is set when the unit is degree,
Circular interpolation (Error code: 199FH) occurs and the positioning will not start. During the positioning control, the operation
decelerates to stop at the detection of the error.
*6 Only linear interpolation axis can use a unit different from that of the reference axis.
Axis operation status during the interpolation control
During the interpolation control, Interpolation is stored in [Md.26] Axis operation status. When the interpolation control is
finished, Standby will be stored. If an error occurs during the interpolation control, both the reference axis and interpolation
axis will perform a deceleration stop, and Error is stored in [Md.26] Axis operation status.
