4-3-2 Selecting
Connection
Components
• Select a leakage breaker for high frequencies and surge resistance.
• 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 current values.
• The leakage breaker is activated at 50% of the rated current. Select a leakage breaker with
approximately twice the 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 and surge-resistant leakage breakers can prevent operation with high-frequency
leakage current because they do not detect high-frequency current.
When using a general leakage breaker, use three times the total of the leakage current given in the
following table as a reference value.
Note These values vary greatly depending on the installation conditions of the motor power cable and the
measurement conditions. Use the values for reference only.
