Linear Interpolation
Section 6-3
Acceleration Time and
Deceleration Time
Acceleration and deceleration times under the PTP control are as follows:
Acceleration time:
Time required until the single axis speed reaches the
maximum feed rate.
Deceleration time:
Time required until the speed control voltage drops to
zero from the maximum feed rate of the single axis.
The acceleration time and deceleration time (feed rate parameters) are set
either from the CX-Motion or by using IOWR in the ladder program.
Overrides can be set to alter the acceleration time and deceleration time. The
acceleration speed, however, will remain constant.
Note
Refer to
6-12 Override Function
for details on the override function.
Triangular Control
If the travel time is shorter than the sum of acceleration time and deceleration
time, triangular control will occur as shown below.
The ratio of acceleration time and deceleration time in the triangular control
will be the same as the ratio of acceleration time and deceleration time set in
the feed rate parameters.

Linear Interpolation
Overview
Mode:
Automatic;
Method:
G language (G01)
Positioning with linear interpolation produces a straight line that connects a
preset starting point to a preset end point using all specified axes (X to U). For
details on using linear interpolation with the G language, refer to
