PTP Control
Section 6-2
6-2
PTP Control
Overview
Mode:
Automatic;
Method:
G language (G00)
Positioning each axis independently from the other axes is called PTP control.
Each axis moves at the preset feed rates: at the acceleration for the preset
acceleration time, the maximum feed rate, and the deceleration for the preset
deceleration time. For details on using PTP control with the G language, refer
to
7-3-1 G00: POSITIONING
.
For example, suppose a control program is executed for moving from the ori-
gin to the X-axis coordinate of 100 and Y-axis coordinate of 50. If the feed
rates, the acceleration times, and the deceleration times are the same for both
axes, X-axis and Y-axis movements will be as illustrated below.
Both the X axis and Y axis move to a coordinate of 50 over the same duration
of time. At this point, the Y axis stops and the X axis moves to a coordinate of
100.
Jogging in the Manual Mode is also performed using PTP control using the
maximum jogging feed rate.

and stops axis operation.
