Be sure to set the pulse range inside the positions of the mechanical stop range.
Example: Using LS20-B804S
The angle of Joint #1 is set from −110 to +110°.
The angle of Joint #2 is set from −120 to +120°.

The Pulse command (Go Pulse command) moves all joints to the specified positions at
the same time. Specify safe positions after considering motion of not only the joints
whose pulse range have been changed, but also other joints.
In this example, Joint #1 is moved to 0° position where is close to the center of its
motion range (pulse value: 327680) when checking Joint #2.
If the arm is hitting the mechanical stops or if an error occurs after the arm hits the
mechanical stops, either reset the pulse range to a narrower setting or extend the
positions of the mechanical stops within the limit.
