6.3 Absolute Reset Procedure
This actuator has been shipped with its home adjusted fully.
The IX-NNN-2515/3515 adopts an absolute encoder, which means that the home will be set upon an absolute
reset.
Absolute data stored in the encoder is backed up with a battery. Therefore, as long as an absolute reset is
performed once, the actuator will not require an absolute reset the next time its power is turned on.
However, absolute data in the encoder may be lost under certain situations such as when the motor has been
replaced or encoder battery voltage has dropped. If the absolute data has been lost, you must perform an
absolute reset.
6.3.1 Absolute Reset Procedure
1. Preparing the absolute reset jig
A jig like the one specified below is needed to perform an absolute reset.
x Absolute reset adjustment jig (type: JG-2)
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 “center of positioning mark label
r1 graduation”
is ensured.)
