Regenerative Energy Absorption By Regeneration Resistor - Omron Omnus FND-X Series User Manual

Operation
3-10-3 Regenerative Energy Absorption by Regeneration
Resistor
If the Position Driver alone cannot absorb the regenerative energy, connect a Regeneration Resistor.
The Regeneration Resistor connects between the P and J terminals at the Position Driver's terminal
block.
Caution Be careful when connecting the Regeneration Resistor. If done incorrectly it will
!
damage the Position Driver.
Caution The Regeneration Resistor heats up to 120°C, so be careful not to place it near
!
equipment or wiring that may be affected by heat. Also be sure to install a radiation
shield that satisfies the heat radiation conditions.
