6 OPTIONS AND PERIPHERAL EQUIPMENT
6.10 Molded-case circuit breakers, fuses, magnetic contactors
Recommended wire
*1 If a servo motor with a capacity lower than the servo amplifier rating is connected, cable sizes based on that motor can be used.
Molded-case circuit breaker/Semiconductor fuse (simple converter)
Recommended wire (simple converter)
*1 Wire sizes differ depending on the total current of the connected servo amplifiers. Use 12 AWG wire if the total current exceeds 12 A.
