PERIPHERAL DEVICE
10-6
10-2) FAB/ELB (molded case circuit breaker and earth leakage breaker)
FAB (molded case circuit breaker) or ELB (earth leakage breaker) is installed in the primary circuit of
the power supply of the servo amplifier for turning power supply on/off and promptly cutting off a fault
current such as short-circuit current.
The type for a single servo amplifier is described here.
The protective functions against overcurrent in the output circuit are built in the servo amplifier.
