Introduction
This controller receives power in order to drive the actuator motor(s) (three-phase/single-phase, 200 to
220 V) and to operate the controller itself (200 to 220 V). (*The single-phase power specification is
applicable only to single-phase controllers.)
The actuator motor drive power supply is controlled independently of the control power supply, and the
internal operations of the controller are different depending on whether it is of the global specification or
standard specification.
With the standard controller, the main CPU in the system performs all self-diagnosis checks and supplies
power to the drive part only when the system can operate properly.
With the global controller, the user must provide a separate circuit that cuts off the three phase 200 VAC
motor power supplied to the controller. If this drive power cutoff circuit is not provided, safe operation of
the controller cannot be guaranteed.
With the global controller, always configure a safety circuit (drive-source cutoff circuit).
x Turn on the controller power before or simultaneously with the motor power.
x Turn off the controller power after or simultaneously with the motor power.
x Before performing a check or inserting/removing a connector, turn off the power and wait for at least 10
minutes. Even after the power is turned off, the internal circuits will continue to carry high voltages for a
short period.
x Duty of cartesian-axis actuators
IAI recommends that our cartesian-axis actuators be used at a duty of 50% or less as a guideline in
view of the relationship of service life and accuracy. The duty is calculated by the formula specified
below:
Duty (%) =
Inactivity time Motion
Time on Decelerati / on Accelerati

X 100
x After turning off the control power, be sure to wait for at least 5 seconds (or 40 seconds in the case of a
P type controller of single-phase specification) before turning it back on. Any shorter interval may
generate “E6D: Drive-source cutoff error.”
x Do not insert or remove connectors while the controller power is on. Doing so may cause a malfunction.
x Precautions for when introducing the linear movement axis absolute specification:
Follow the steps below to initialize the absolute data backup battery circuit and thereby prevent early
consumption of the battery:
[1] Set the absolute data backup battery enable/disable switch to
the bottom position.
(The controller is shipped with this switch set to the bottom
position.)
[2] Connect the encoder cable.
[3] Turn on the power.
[4] Set the absolute data backup battery enable/disable switch to
the top (ENB) position.
If the encoder cable of a linear movement axis was removed to
relocate the actuator, etc., you must always perform the above
steps.
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.
