Chapter 11: Stopping Operation
11-1 Overrun (M L2 + Sequence controller)
The graph below shows the relation between piston speed and overrun.
(The length of overrun is changed by piston speed, load, tubing condition and control method. Be sure to
adjust the stop signal position, etc. by trial operation with the actual machine.)
11-2 Dispersion of stopping position
When cylinder is stopped intermediately, the stopping position is not fixed.
Dispersion of stopping position is changed by piston speed, load, tubing condition and control method,
etc. Please refer to the table below.

When cylinder is stopped inter-

“idle running distance”
(from detection of stop signal to
beginning of brake operation)
and
“braking distance “(from beginning
of brake operation to slider stop) are
occurred as shown in the figure left.
