Controller.
Set the pulse range corresponding to the new
positions of the mechanical stops.
Be sure to set the pulse range
inside the positions of the mechanical stop range.
Using LS20-804S
The angle of Joint #1 is set from –110 degrees to +110 degrees.
The angle of Joint #2 is set from
125 degrees to +125 degrees.
Execute the following command
s from the [Command Window].
>JRANGE 1,
-400498, 400498 ' Sets the pulse range of Joint #1
>JRANGE 2,-
284445, 284445 ' Sets the pulse range of Joint #2
>RANGE ' Checks the setting using Range
-400498, 400498, -284445, 284445, -283853
, 0, -344064, 344064
Move the arm by hand until it touches the mechanical stops, and make sure that the
arm does not hit
any peripheral equipment during operation.
perate the joint changed at low speeds until it reaches the positions of the
maximum pulse range.
Make sure that the arm does not hit the mechanical
stops.
(Check the position of the mechanical stop and the motion range you set.)
: Using LS20-804S
The angle of Joint #1 is set from -110 degrees to +110 degrees.
The angle of Joint #2 is set from
125 degrees to +125 degrees.
Execute the following command
s from the [Command Window].
>MOTOR ON ' Turns ON the motor
>CP ON ' Enters low-power mode
>SPEED 5 ' Sets at low speeds
>PULSE -400498,0,0,0 ' Moves to the min. pulse position of Joint #1
>PULSE 400498,0,0,0 ' Moves to the max. pulse position of Joint #1
>PULSE 327680,-284445,0,0 ' Moves to the min. pulse position of Joint #2
>PULSE 327680,284445,0,0 ' Moves to the max. pulse position of Joint #2
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 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.
