Performance Specifications
If the regenerative energy exceeds the 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
Servo Drive may be damaged by burning if connected to the wrong terminals. The External
Regeneration Resistor will heat up to approximately 120
wiring that is easily affected by heat. Attach radiator plates suitable for the heat radiation conditions.
If an External Regeneration Resistor is necessary, connect it between B1 and B2 as shown in the
diagram below.

Regeneration
Connect the thermal switch output so that the main circuit power supply is
shut OFF when the contacts open. The resistor may be damaged by
burning, or cause fire if it is used without setting up a power supply shutoff
sequence using the output from the thermal switch.
