INTELLIGENT ACTUATOR
Introduction
The X-SEL Controller is available with one to four axes. As with the conventional SEL Controller, it can be
used with various actuators. When connecting actuators, always use dedicated cables.
 Actuator duty
IAI recommends that our actuators be used at a duty of 50% or less in view of the relationship of
service life and precision. The duty is calculated by the formula below:
Duty (%) =
hours Stopped hours Operating
hours Operating

X 100
 After turning off the main power, be sure to wait for at least 5 seconds before turning it on.
Any shorter interval may generate “E88: Power system error (Other).”
 Do not plug in/out the connectors while the power is still supplied to the controller. Doing so may result
in malfunction.
 Item to note when installing the absolute-data backup battery (absolute specification)
The battery installation procedure specified below must be followed to initialize the battery circuit and
thereby prevent premature consumption of the battery. Install the battery according to this procedure:
[1] Connect the encoder cable.
[2] Turn on the power.
[3] Install the absolute-data backup battery.
The above operation must be performed every time the encoder cable was unplugged to relocate the
system, etc.
Read the operation manual for each actuator. If you have purchased our optional PC software and/or
teaching pendant, read the respective operation manuals, as well.
