Connecting Regenerative Resistors
The method for connecting regenerative resistors is shown below.
Servopacks with Capacities of 400 W or Less
Connect an external regenerative resistor between the Servopack’s B1 and B2 terminals.

*
The user must provide the regenerative resistor.
Servopacks with Capacities of 0.5 to 5.0 kW
Disconnect the wiring between the Servopack’s B2 and B3 terminals and connect an external
regenerative resistor between the B1 and B2 terminals.

*
The user must provide the regenerative resistor.
Servopacks with Capacities of 6.0 kW or More
Servopacks with capacities of 6.0 kW or more do not have regenerative resistors built in. A re-
generative resistor must be connectedexternally. Thefollowing RegenerativeResistor Unitsare
available for this purpose.
