Positioning Controls

5-1 Positioning Controls
PTP Control
CP Control
Interrupt Inching

The MC Unit offers the following three positioning controls:
PTP control
CP control (linear interpolation and circular interpolation)
Interrupt inching
Control programs are created in the G language.
Note Refer to Section 6 G Language for information on the G language.
The PTP control is used to position each axis (X and Y axis) independently from
other axes. Positioning time depends on the travel distance and speed of each
axis.
Example: Moving from the origin to the X-axis coordinate of 100 and Y-axis
coordinate of 50.
50
0
The illustration shows movements when the high-speed feed
rate for the X axis is set to the same feed rate as the Y axis.
CP control is used to position by designating not only the starting point and the
target point but also the path between these two points.
Interrupt inching is used to perform speed control until an external signal is input
and to perform positioning control for inching with the external signal.
