11.6 No-fuse breakers, fuses, magnetic contactors
Always use one molded-case circuit breaker and one magnetic contactor with one servo amplifier. When using a
fuse instead of the molded-case circuit breaker, use the one having the specifications given in this section.
When using two different types of motors in combination from a rotary servo motor, a linear servo motor or a
direct drive motor, select a molded-case circuit breaker, a fuse or a magnetic contactor temporarily assuming
that the same type of the motors are used for both axes. After selecting for the two types, use the larger molded-
case circuit breaker, fuse or magnetic contactor.

Note 1. Refer to appendix 4(8) to use the servo amplifier as a UL/CSA compliant product.
2. Be sure to use a magnetic contactor with an operation delay time of 80ms or less. The operation delay time is the time interval
between current being applied to the coil until closure of contacts.
