Components
This section explains the criteria for selecting the connection components required to improve noise
resistance.
Understand each component’s characteristics, such as its capacity, performance, and applicable range
when selecting the connection components.
For more details, contact the manufacturers directly.
When selecting a no-fuse breaker, consider the maximum input current and the inrush current.
z
Maximum Input Current
•
The momentary maximum output of Servo Drive is approximately 3 times the rated output, and
can be output for up to 3 seconds.
Therefore, select no-fuse breakers with an operation time of at least 5 seconds at 300% of the
rated current ratio. General or low-speed no-fuse breakers are suitable.
•
Select a no-fuse breaker with a rated current greater than the total effective load current of all the
motors (when multiple Servo Drives are used).
The rated current of the power supply input for each Motor model is provided in 4-2-2 Main Circuit
and Linear Motor Connections on page 4-18.
•
Add the current consumption of other controllers, and any other components when selecting.
z
Inrush Current
•
The following table shows the Servo Drive inrush currents.
•
With low-speed no-fuse breakers, an inrush current 10 times the rated current can flow for 0.02
seconds.
•
When the power of more than one Servo Drive is turned ON simultaneously, select a no-fuse
breaker with a 20-ms allowable current that is greater than the total amount of the inrush current in
the following table.
