(8) Limits to interpolation control

There are limits to the interpolation control that can be executed and speed ([Pr.20] Interpolation speed 
designation method) that can be set, depending on the "[Pr.1] Unit setting" of the reference axis and interpolation 
axis. (For example, circular interpolation control cannot be executed if the reference axis and interpolation axis 
units differ.)
The following table shows the interpolation control and speed designation limits.

: Setting possible, 

: Setting not possible.

*1

"mm" and "inch" unit mix possible.

*2

"degree" setting not possible.
The error "Circular interpolation not possible" (error code: 535) will occur and the positioning cannot be started if circular 
interpolation control or 3-axis helical interpolation control is set when the unit is "degree".
The machine will immediately stop if "degree" is set during positioning control.

*3

The unit set in the reference axis will be used for the speed unit during control if the units differ or if "mm" and "inch" are 
combined.

*4

Only for the linear interpolation axis, a unit different from the one set for the reference axis can be used.

*5

When a "composite speed" is set and positioning is started in the 2- to 3-axis speed control or 4-axis linear interpolation 
control, the error "Interpolation mode error" (error code: 523) will occur.

*6

When a "reference axis speed" is set and positioning is started in the circular interpolation control or 3-axis helical 
interpolation control, the error "Interpolation mode error" (error code: 523) will occur.

(9) Axis operation status during interpolation control

"Interpolation" will be stored in the "[Md.26] Axis operation status" during interpolation control. "Standby" will be 
stored when the interpolation operation is terminated. Both the reference axis and interpolation axis will carry out 
a deceleration stop if an error occurs during control, and "error occurring" will be stored in the operation status.
