
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.
• When performing frequent start and stop operation, usage rate of the regenerative brake can be increased by using
the brake resistor or the brake unit.
• 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.
