SAFETY PRECAUTIONS
s–5
CAUTION
F Ensure that the combination of motor and amplifier is appropriate.
F Ensure that valid parameters are specified.
Specifying an invalid parameter for the combination of motor and amplifier may not only
prevent normal operation of the motor but also result in damage to the amplifier.
F Ensure that the amplifier and peripheral equipment are securely
connected.
Check that the magnetic contactor, circuit breaker, and other devices mounted outside the
amplifier are securely connected to each other and that those devices are securely connected to
the amplifier.
F Check that the amplifier is securely mounted in the power magnetics
cabinet.
If any clearance is left between the power magnetics cabinet and the surface on which the
amplifier is mounted, dust entering the gap may build up and prevent the normal operation of
the amplifier.
F Apply appropriate countermeasures against noise.
Adequate countermeasures against noise are required to maintain normal operation of the
amplifier. For example, signal lines must be routed away from power supply lines and power
lines.
