1st-axis Mechanical End Change

[ 1 ] What is the 1st-axis Mechanical End Change?
At the time of delivery from the factory, mechanical ends are set in the
VM-6083G/VM-60B1G series so that the stroke of the 1st axis will be ±170°.
Changing the mechanical ends of the 1st axis by adding mechanical stops is called a
mechanical end change.
The figure below shows the mechanical stop positions for mechanical end change.
Given below is an example when the mechanical stops are positioned as specified in
the table below.
To change the mechanical ends, the following four types of mechanical stop parts are
required.
- Mechanical stop (4 pieces)
- Fixture block A
- Fixture block B
- Plate
The figures on the following pages show the reference drawings of those mechanical
stop parts. Referring to those drawings, you should prepare mechanical stop parts as
necessary so that your desired motion space may be set.
If the 1st axis comes into contact with any mechanical stop because of the width of the
stopper and its bolt, the angle of the 1st axis is different between the positive and
negative directions. The table below shows the angles of the 1st axis in the positive
and negative directions when it is in contact with each mechanical stop.
