7. POSITIONING CONTROL
[Program Example]
Downloaded from ManualsNet.com
POINT
(1) Do not set the travel value to zero for fixed-pitch feed control.
The following results if the travel value is set to zero:
(a) If all 3-axes are set to zero, the fixed-pitch feed ends with no feed
taking place.
(b) If the travel value is set to zero for any of the 3-axes, fixed-pitch feed
control will not occur at the normal positioning speed for the axis or
axes set to a non-zero travel value.
This program conducts fixed-pitch feed control using 3-axes linear interpolation
under the conditions below.
(1) System configuration
Fixed-pitch feed control using 3-axes linear interpolation of Axis, 1, Axis 2, and
Axis 3.
(2) System configuration
(a) The positioning conditions are shown below.
