The instantaneous maximum output of SERVOPACK is approximately 3 times of the rated output for maximum for 3 seconds. Accordingly, select a molded-case circuit breaker whose breaking time is 5 seconds or more at 300% of SERVOPACK rated current. The general-purpose low-speed acting molded-case circuit breakers are applicable.
The power supply capacity per SERVOPACK when using a servomotor is described in 2.5.2 Molded-case Circuit Breaker and Fuse Capacity. Select a molded-case circuit breaker with the capacity larger than the effective load current (when using more than multiple SERVOPACK) calculated from the total power supply capacity.
The consumption of other controllers must be considered when selecting a molded-case circuit breaker
(2) Inrush Current
Refer to 2.5.2 Molded-case Circuit Breaker and Fuse Capacity for SERVOPACK inrush current.
The allowable inrush current for a low-speed acting molded-case circuit breaker is approximately 10 times of the rated current for 0.02 seconds.
When turning ON multiple SERVOPACK simultaneously, select a molded-case circuit breaker with the allowable current for 20 ms larger than the total inrush current shown in 2.5.2 Molded-case Circuit Breaker and Fuse Capacity.
