(*1) Continuous regenerative braking allowable capacities vary according to the rated capacity and resistance of the resistor for reasons of endurance.

(*2) To use braking resistor, installing a braking resistor drive circuit option is needed.

(*3) To use braking resistor (DGP600 series), installing a braking resistor drive circuit option is needed. And overload relay on this table is needed.

(*4) Type forms of Toshiba Schneider Electric Ltd. products.

4) Connectable braking resistors and their minimum resistances

The table below lists externally-connectable braking resistors and their minimum admissible resistances. Do not connect any braking resistor with a resistance (total resistance) smaller than the minimum resistance admissible for it.
