Regenerative Brake Selection And Dc Feeding Mode - Mitsubishi Electric 800 Series Instruction Manual

(G) Control parameters
5.16.10
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 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.

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.
