(*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.
