AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
The value of the inrush current varies depending on the input voltage to the Servo Drive. The values
shown above are for the following input voltages.
• Select a leakage breaker which is made for high frequency and surge resistance.
• When you determine the threshold value for leakage current detection, add the total leakage current
from all devices that are connected to the same breaker.
• Refer to the catalogs from the manufacturers for details on how to select a leakage breaker and
ensure a sufficient margin.

*1. If an external regeneration resistor is attached, the inrush
currents of the main circuit power supplies in the above table
will be increased.
(Increase in current =
√
2 × main circuit power supply volt-
age/external regeneration resistance)
