■Minimum resistance of connectable braking resistors
The minimum allowable resistance values of the externally connectable braking r esistors are listed in the table
below.
Do not connect braking resistors with smaller resultant resistance than the l isted minimum allowable resistance
values.
(For 200kW or greater models, a dynamic braking resistor drive unit (op tional separate unit) is needed.)
