For linear motion or other similar motion, overtraveling of the work may cause
mechanical damages. To avoid this, it is necessary to provide limit switches at
each end so that traveling over the limit switch position can be inhibited.
<Notes>
1 . With Pr04 = 0 and CCW/CW off (not connected to COM-),
the amplifier will stop the motor with "overtravel limit
input error" assuming that traveling over the limit occurs
in both the CCW and CW directions.
2 . Y o u c a n s p e c i f y w h e t h e r o r n o t t o u s e t h e
dynamic brake during deceleration after CCW
or CW overtravel limit input (CCWL or CWL)
becomes active. For details, see the description
of Pr66 (DB inhibition at overtravel limit).
