1.2 WARNINGS AND CAUTIONS RELATING TO MOUNTING
1.2.1 Warning
WARNING
- 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.
Servo 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 resistor
become extremely hot. Never touch them directly. An
appropriate structure should also be considered.
