(4)
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.
Example:
Using G6-**1S*
The angle of Joint #1 is set from 135 degrees to +135 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,-1310720,6553600 ' Sets the pulse range of Joint #1
>JRANGE 2,-2275556,+2275556 ' Sets the pulse range of Joint #2

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.
(6)
O
perate the joint changed at low speeds until it reaches the positions of the
minimum
and
maximum pulse range. Make sure t
hat the arm does not hit the mechanical
stops.
(Check the position of the mechanical stop and the motion range you set.)
Example
: Using G6-**1S*
The angle of Joint #1 is set from -85 degrees to +115 degrees.
The angle of Joint #2 is set from
-
132 degrees to +132 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 -1310720,0,0,0 ' Moves to the min. pulse position of Joint #1
>PULSE 6553600,0,0,0 ' Moves to the max. pulse position of Joint #1
>PULSE 2621440,-2275556,0,0 ' Moves to the min. pulse position of Joint #2
>PULSE 2621440,2275556,0,0 ' Moves to the max. pulse position of Joint #2
The
Pulse command (Go Pulse command) moves all joints to the specified position
s
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:
2621440
) when checking Joint #2.
If the arm
is hitting the mechanical stop
s or if an error occurs after the arm hits the
mechanical stops
, either reset the pulse range to a
narrower setting or extend the
position
s of the mechanical stops within the limit.
