(3) 3rd-axis Mechanical End Positions
The 3rd-axis mechanical end positions available are shown below.
Note: Mounting the 3rd-axis mechanical stop limits the workable angle of the 3rd axis so that the 3rd
axis cannot move up to the factory default angle.
Observe the following.
(1) The 3rd axis cannot move overriding 150° in the positive direction, so set the
positive-direction software motion limit for the 3rd axis in the negative side than 150°.
(2) In the VS-6556G series, mounting the 3rd-axis mechanical stop limits the workable angle
of the 3rd axis so that the 3rd axis cannot move overriding -25° (-20° 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 -25° (-20°).
(3) In the VS-6577G series, the 3rd-axis cannot move overriding -65° in the negative
direction. Set the negative-direction software motion limit for the 3rd-axis in the positive
side than -65°.
(4) 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 3rd-axis motion range when a
positive or negative direction mechanical stop is mounted at each of the mechanical end positions
available.
