Introuduction
This controller receives two types of power from external power sources: one for driving the motor (three-phase
or single-phase, 200 to 220 V) and the other for control (single-phase, 200 to 220 V).
* A single-phase power source is required only for controllers of single-phase specification.
The 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.
If your controller is of the global specification, be sure to provide a safety circuit (drive-power cutoff circuit).
This controller can be configured with one to six axes. Just like other conventional SEL controllers, this controller
can be combined with various actuators. When connecting an actuator, be sure to use a dedicated cable.
Turn on the controller power before or simultaneously with the motor power.
Turn off the controller power after or simultaneously with the motor power.
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.
About actuator duty
IAI recommends that our actuators be used at a duty of 50% or less as a guideline in view of the relationship
of service life and precision:
Duty (%) =
noitoMemitytivitcanI
noemiTDeceleratino/Accelerati
X 100
After turning off the control power, be sure to wait for at least 5 seconds (40 seconds for single-phase P
type controllers) before turning it back on.
An “E6D, Drive-source cutoff relay error” may generate if the control power is turned off and then turned on
again too quickly.
Do not insert or remove connectors while the controller power is on. Doing so may cause malfunction.
Items to note when introducing an absolute-specification controller
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.
(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.
The above steps must be performed after the encoder cable has been
removed due to relocation, 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.
* Utmost effort has been made to ensure that the information contained in this manual is true and correct.
