G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
If the regenerative energy exceeds the regeneration absorption capacity of the Servo Drive, connect an
External Regeneration Resistor.
Connect the External Regeneration Resistor between B1 and B2 terminals on the Servo Drive.
Double-check the terminal names when connecting the resistor because the drive may be damaged if
connected to the wrong terminals.
The surface of the External Regeneration Resistor will heat up to approximately 200°C. Do not place it
near equipment and wiring that is easily affected by heat. Attach radiator plates suitable for the heat
radiation conditions.
