6. Precautions for Use
6.3 Absolute Reset Procedure
The home of your actuator has been adjusted fully prior to its shipment from IAI.
IX-NNN-50**/60**/70**/80** actuators adopt an absolute encoder, which means that their home is set by
means of an absolute reset.
The absolute data in the encoder is backed up using a battery, so once an absolute reset is performed, you
need not repeat an absolute reset the next time the power is turned on.
However, an absolute reset may be required after replacing the motor or when the encoder has lost its
absolute data due to detection of low encoder battery voltage or for other reasons.
6.3.1 Absolute Reset Procedure
(1) Preparation for absolute reset jig
The following jig is required when performing an absolute reset:
x Absolute reset adjustment jig Model: JG-1 (IX-NNN50 /60 )
JG-3 (IX-NNN70 /80 )
An absolute reset adjustment jig is always required when performing an absolute reset of the rotational axis
or vertical axis. However, the jig is not always necessary when performing an absolute reset of arm 1 (axis
1) or arm 2 (axis 2).
(Rotation data can be reset as long as a positioning accuracy of “positioning mark label
r 1 graduation” is
ensured.)
