TANGENTIAL CONTROL.

·312·

(REF: 1709)

When jogging the axes, the CNC cancels tangential control Once the movement has ended,

the CNC re-activates tangential control in the same conditions as before.

MDI mode.

The MDI mode may be accessed from jog mode to activate tangential control and move the

axes using blocks programmed in MDI. The tangential axis cannot be moved while tangential

control is active.
