Regenerative Energy Absorption With An External Regeneration Resistor - Omron R88M-K Series User Manual

Regenerative Energy Absorption with an External Regeneration
Resistor
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 approx. 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.
