6POSITIONING CONTROL(3)Circular interpolation control

The angular speed is controlled with the setting speed at the circular interpolation control.

Control with the setting speed

6.1.3 Control units for 1 axis positioning control

It is controlled in the control units specified with the fixed parameters at the 1 axis positioning control.

(The control unit specified with the parameter block is ignored.)

6.1.4Control units for interpolation control

(1)The interpolation control units specified with the parameter block and the control units of the fixed parameter are checked.

If the interpolation control units specified with the parameter block differ from the control units of the each axis fixed parameter for the interpolation control, it shown below.
