3.4 Typical Main Circuit Wiring Examples

• Use a molded-case circuit breaker (1QF) or fuse to

protect the servo system.

Always use a molded-case circuit breaker (1QF) or

fuse to protect the servo system from accidents

involving different power system voltages or other

accidents.

• Install a ground fault detector.

The SERVOPACK does not have a built-in protec-

tive circuit for grounding.

To configure a safer system, install a ground fault

detector against overloads and short-circuiting, or

install a ground fault detector combined with a

molded-case circuit breaker.

• Do not frequently turn power ON and OFF.

• Frequently turning power ON and OFF causes

elements inside the SERVOPACK to deterio-

rate. Do not use the servo drive with an applica-

tion that requires frequently turning power ON

and OFF.

• After the actual operation starts, the allowable

interval for turning power ON and OFF is one

hour or longer.
