Galil Motion Control DMC-42 0 Series, Руководство пользователя

Страница: 66 / 218

Note the controller treats the point where the velocity passes through zero as the end of one move, and the
beginning of another move. IT is allowed, however it will introduce some time delay.
Trippoints
Most trippoints are valid for use while in the position tracking mode. There are a few exceptions to this; the AM
and MC commands may not be used while in this mode. It is recommended that MF, MR, or AP be used, as they
involve motion in a specified direction, or the passing of a specific absolute position.
