POINTS
The fixed acceleration/deceleration method is a type of acceleration/
deceleration processing whereby even if the command speed changes, the
time taken up by acceleration/deceleration remains fixed.

(1) When the fixed acceleration/deceleration method is used, the following
processing and parameters are invalidated.
• Rapid stop deceleration time in parameter block
• Completion point designation method for speed change point
• S curve acceleration/deceleration
(2) When the type of positioning operation shown below (constant-speed
control) is performed, the speed processing for each axis is as shown
below.
