Reverse positioning accuracy
(Lost motion)
(in compliance with JIS B6201)
a) Move the output rod to the push-out direction, and then move it to the center of displacement (±0mm). The point is
Ao.
b) From Ao, feed it 1mm to the push-out direction. The point is A
1
.
c) From Point A
1
, feed it 1mm to the pull-in direction, and measure the point. The point is P
1
.
d) From Point P
1
, feed it 1mm further to the pull-in direction, and measure the point. The point is A
1
'.
e) From Point A
1
', feed it 1mm to the pull-in direction, and measure the point. The point is P
1
'.
f) Repeat the steps b to e 7 times. The reversed positioning accuracy (lost motion) is the difference between the
