(3) 2nd-axis Mechanical End Positions
The 2nd-axis mechanical end positions available are shown below.
Note: Mounting the 2nd-axis mechanical stop limits the workable angle of the 2nd axis so that the
2nd axis cannot move up to the factory default angle.
Observe the following.
(1) The 2nd axis cannot move overriding -60° in the negative direction, so set the
negative-direction software motion limit for the 2nd axis in the positive side than -60°.
(2) In the VS-6556 series, mounting the 2nd-axis mechanical stop limits the workable angle
of the 3rd axis so that the 3rd axis cannot move overriding -100° (-30° on the UL-Listed
models) in the negative direction. Set the negative-direction software motion limit for the
3rd axis in the positive side than -100° (-30°).
(3) Be careful with the design of the mechanical stop. Depending upon the shape of the
mechanical stop prepared by the customer, the axis may hit the mechanical stop before
the software motion limit described above is activated.
Motion range (software motion limit value): The table below lists the 2nd-axis motion range when a
positive or negative direction mechanical stop is mounted at each of the mechanical end positions
available.
