3-2 Selecting
Connection
Component
This section describes the criteria for selecting connection components that are required to improve
noise immunity.
Thoroughly understand the characteristics such as capacity, performance, and the range of application
of the connection components before you select them.
Consult the manufacturer for details of the parts.
Select a molded case circuit breaker based on the maximum input current and inrush current.
z Maximum input current
• The momentary maximum output of the Servo Drive is approximately three times as much as the
rated output, and the maximum output duration is three seconds.
Therefore, select a molded case circuit breaker which can operate 10
seconds or more at 300% of
the rated current.
• Select a molded case circuit breaker with a rated current larger than the sum of the effective load
current (when multiple Servo Drives are used). Refer to Main Circuit and Motor Connections on
page 3-9 for the rated current of the power supply input for each motor.
• When you select a molded case circuit breaker, add the current consumption by other devices
such as the Controller.
z Inrush Current
• The following table shows the inrush current of the Servo Drives.
• The amount of inrush current that a low-speed type molded case circuit breaker can flow for 0.02
seconds is approximately 10 times higher than the rated current.
• To turn ON the power supply for multiple Servo Drives simultaneously, select a molded case cir-
cuit breaker whose allowable current in 20 ms is larger than the sum of the inrush currents shown
in the following table.
• The inrush current of the control power supply is limited by the output capacity of the DC power
supply in use.
