Abstract
The servo control method operates a set value of a first-order lag time constant of a feedback compensation by both a detected mechanical position value and a transfer function corresponding to a change of an angular velocity about each axis under a multiple-axes simultaneous control. Further, the servo control method sets a feedforward amount so that the transfer function about the each axis is the same.
Claims5
A servo control method comprising the steps of:
- operating both a set value of a first-order lag time constant of a feedback compensation by a detected mechanical position value and a transfer function corresponding to a change of an angular velocity for each axis under a multiple-axes simultaneous control;
- and
- setting a feedforward amount so that the transfer function about the each axis is the same.
