Regenerative brake selection and DC feeding
mode
• When performing frequent start and stop operation, usage rate of the regenerative brake can be increased by using
the optional high-duty brake resistor (FR-ABR) or the brake unit (FR-BU2, BU, FR-BU).
• When using continuously in regenerative condition, use the power regeneration common converter (FR-CV) or
power regeneration converter (MT-RC). The high power factor converter (FR-HC2) can be used also to reduce
harmonics, improve power factor, and operate continuously in the regenerative status.
• It is possible to choose between the DC feeding mode 1, which will operate with DC power supply (terminals P and
N), and DC feeding mode 2, which will normally operate in AC power supply (terminals R, S, and T) and operate in
DC power supply (terminal P and N), such as batteries, at the time of power failure.
• While the power is supplied only to the control circuit, the reset operation when the power is supplied to the main
circuit can be selected.

While the power is supplied only to the control circuit with Pr.30 = "100 or higher", the inverter reset is not performed when the power is supplied to the
main circuit.
