2nd-axis Mechanical End Change

At the time of delivery from the factory, mechanical ends are set in the VLA series robots so that the stroke of the 2nd axis is from -60° to +125°.
Changing the mechanical ends of the 2nd axis by adding mechanical stoppers is called a mechanical end change.
When you use adjustable mechanical stoppers (option), you can limit the stroke of the 2nd axis in units of 15° (25° for the rear stop position) in both directions.

The figure below shows the mechanical stopper installation positions.

Components

1. Adjustable mechanical stopper for 2nd axis (quantity : 2)
2. Hexagon socket-head bolt M12 × 45mm, strength class: 12.9 (quantity : 12)

Mounting Procedure

1

Place the adjustable mechanical stopper (A) in the desired position on the robot 2nd axis.

2

Tighten two fixing bolts (B) with tightening torque 143Nm.

3

If you limit the opposite side as well, mount it in the same way.

Precautions

• Remove any fixtures / piping installed on the robot that interfere with the fixing part of the adjustable mechanical stopper.
• This option can limit the 2nd axis stroke in two directions. If you want to limit the stroke in only one direction, use only one of two stoppers.
