External Regeneration Resistor Specifications

If the Servomotor's regenerative energy is excessive, connect an External
Regeneration Resistor.
Note 1. External Regeneration Resistors cannot be connected to Servo Drivers of between 30 to
200 W.
Connection to a 400-W Servo Driver is usually not required. If the Servomotor's regenerative
energy is excessive, connect an External Regeneration Resistor between B1 and B2.
For a 750-W Servo Driver, B2 and B3 are normally short-circuited. If the Servomotor's re-
generative energy is excessive, remove the short bar between B2 and B3 and connect an
External Regeneration Resistor between B1 and B2.
Note 2. Refer to Surge Absorbers for External Regeneration Resistor selection details.
