Resetting the origin
5.6.3 ABS origin method
When the origin setting of the robot is performed for the first time, this product records the angular position of the
origin within one rotation of the encoder as the offset value. If the origin setting is performed according to the
ABS origin method, this value is used to suppress variations in the origin setting operations and to reproduce the
initial origin position accurately.
This operation is carried out with the teaching pendant. Set the mode of the controller to "MANUAL", and set the
[ENABLE] switch on the teaching pendant to "ENABLE" to enable the teaching pendant.
First, set to the ABS mark arrow of the axis for which the origin is to be set with jog operation. This can be set for
all axes simultaneously or each axis independently.
To align the ABS marks, view the robot from the front. The deviation between the end points of the two triangular
marks must be 1 mm or less.
The positions where the ABS mark is attached are shown in below. Refer to
for details on the jog operation.
Note that if the ABS marks are peeled off, the positions can be matched using the following alternative methods.
*Match the ruling lines of the ABS mark mounting position surfaces.
