A06B-6114-H106 FANUC Servo Amplifier αi Series

This manual includes safety precautions for protecting the user and preventing damage to the machine. Precautions are classified into Warning and Caution according to their bearing on safety. Also, supplementary information is described as a Note. Read the Warning, Caution, and Note thoroughly before attempting to use the machine.

– Check the specification code of the amplifier.
Check that the delivered amplifier is as originally ordered.
– Mount a ground fault interrupter.
To guard against fire and electric shock, fit the factory power supply or machine with a ground fault interrupter (designed for use with an inverter).
– Securely ground the amplifier.
Securely connect the ground terminal and metal frame of the amplifier and motor to a common ground plate of the power magnetic cabinet.
– Be aware of the weight of the amplifier and other components.
Control motor amplifiers and AC reactors are heavy. When transporting them or mounting them in the cabinet, therefore, be careful not to injured yourself or damage the equipment. Be particularly carefull not to jam your fingers between the cabinet and amplifier.
– Never ground or short-circuit either the power supply lines or power lines. Protect the lines from any stress such as bending. Handle the ends appropriately.
– Ensure that the power supply lines, power lines, and signal lines are securely connected.
A loose screw, loose connection, or the like will cause a motor malfunction or overheating, or a ground fault. Be extremely careful with power supply lines, motor power lines, and DC link connections through which a large amount of current passes, because a loose screw (or poor contact in a connector or poor connection between a connector terminal and a cable) may cause a fire.
– Insulate all exposed parts that are charged.
– Never touch the regenerative discharge resistor or radiator directly.
The surface of the radiator and regenerative discharge unit become extremely hot. Never touch them directly. An appropriate structure should also be considered.
