Leakage Breaker
 Select leakage breakers designed for protection against ground faults.
 When selecting leakage breakers, remember to add the leakage current from devices other than
the motor, such as devices using a switching power supply, noise filters, inverters, and so on.
To prevent malfunction due to inrush current, we recommend using a leakage breaker of 10 times
the total of all leakage current values.
 The leakage breaker is activated at 50% of the rated current. Select a leakage breaker with
enough capacity.
 For details on leakage breakers selection method, refer to the manufacturer's catalog.
 Because switching takes place inside the Servo Drives, high-frequency current leaks from the SW
elements of the Servo Drive, the armature of the motor, and the cables.
High-frequency, surge-resistant leakage breakers, because they do not detect high-frequency
current, can prevent operation with high-frequency leakage current.
When using a general leakage breaker, use 3 times the total of the leakage current given in the
following table as a reference value.
