(2) Specifications
(3) Precautions
Circuit Breakers
• Select a breaker for inverters.
• High-frequency current leaks from the servomotor armature because of switching operations inside the SER-
VOPACK.
(a) Maximum Input Current
• The instantaneous maximum output of SERVOPACK is approximately 3 times of the rated output for
maximum 3 seconds. Accordingly, select a circuit breaker whose operating time is 5 seconds or more at
300% of SERVOPACK rated current.
The general-purpose and low-speed acting molded-case circuit breakers are applicable.
• The power supply capacity per SERVOPACK when using a servomotor is described in 2.6.2 Molded-case
Circuit Breaker and Fuse Capacity. Select a circuit breaker with the capacity larger than the effective
load current (when using multiple SERVOPACKs) calculated from the total power supply capacity.
• The power consumption of other controllers must be considered when selecting a circuit breaker.
(b) Inrush Current
• Refer to 2.6.2 Molded-case Circuit Breaker and Fuse Capacity for SERVOPACK inrush current.
• The allowable inrush current for a low-speed acting circuit breaker is approximately 10 times of the rated
current for 0.02 seconds.
• When turning ON multiple SERVOPACKs simultaneously, select a molded-case circuit breaker with the
allowable current for 20 ms larger than the total inrush current shown in 2.6.2 Molded-case Circuit
Breaker and Fuse Capacity.
