Chapter 1 Safety Precautions
The X-SEL Controller can be combined with a maximum of four actuators of different types, and is able to
provide integrated control over the entire system including peripherals. In other words, the X-SEL
Controller has the ability to control systems of all sizes ranging from a small system to a large factory
automation system. In general, however, the occurrence rate of accidents due to wrong operation or
carelessness will rise as the system becomes larger and more complex. Please give due consideration to
safety measures.
This system product was developed as a drive unit for an automated machine, etc., and as such the
maximum torque and speed are limited to levels acceptable for an automatically driven machine. However,
strict observance of the following items is requested to prevent unforeseen danger. Also read the
appendix entitled, “Safety Rules and Others.”
1. Do not handle this product in manners not specified in this manual. If you have any question regarding
the content of this manual, please contact IAI.
2. This controller is designed to perform all cutoff controls of the motor drive power to actuate an
emergency stop, enable the controller operation, etc., using an external circuit. Be sure to provide a
drive-power cutoff circuit externally to the main controller circuit.
The customer must determine and install an appropriate safety circuit meeting the required safety
category according to the operating condition of the final system.
The motor drive-power circuit has no built-in protective element such as a fuse. The customer must
provide appropriate circuit protection.
3. Always use the specified, genuine IAI cables for wiring between the controller and the actuator.
4. Do not enter the operation area of the machine while the machine is operating or ready to operate (the
controller power is on). If the machine is used in a place accessible to other people, provide an
appropriate safety measure such as enclosing the machine with a cage.
5. When assembling/adjusting or maintaining/inspecting the machine, always turn off the controller power
at the source beforehand. The operator should display in a conspicuous place a plate or other sign
saying that operation is in progress and that the power should not be turned on. The operator should
keep the entire power cable beside him or her to prevent another person from inadvertently plugging in
the cable.
6. When two or more operators are to work together, set call-out signals to ensure safety of all personnel
during the work. In particular, a person turning on/off the power or moving an axis—either via a motor
or manually—must always say what he or she is going to do out loud and confirm the responses from
the others first before actually performing the operation.
