•
In the case, S/W upper/lower limit detection is available as long as origin is set and the position
mark during constant speed operation is “Mark”
(11) Use of Upper/Lower Limits
• To use upper/lower limits during operation, it should be set as “Use”.
• Upper/Lower limit input contact point is fixed as the table below and it can be used as normally
closed contact point (B contact point).
•
If ‘No use’ is set, it does not detect upper/lower limits and is available with general input contact.
