6. Connecting the regenerative unit TS-X TS-P
The regenerative unit absorbs regenerative current produced during motor speed reduction and radiates it
as heat. A regenerative unit is required when operating certain robot models specified by YAMAHA or when
handling large-inertia loads. Use the YAMAHA-specified dedicated cable to connect a regenerative unit to
the controller.

The controller must be grounded to prevent electrical shocks in case of electrical leakage, and to prevent equipment
malfunctions due to electrical noise.
A Class D or higher grounding (grounding resistance of 100
