When making frequent starts/stops, use the optional brake unit (FR-BU2, BU, FR-BU, MT-BU5) to increase the
regenerative brake duty.
Use a power regeneration common converter (FR-CV) or power regeneration converter (MT-RC) for
continuous operation in regenerative status.
Use a high power factor converter (FR-HC, MT-HC) to reduce harmonics, improve the power factor, or
continuously use the regenerative mode.
You can select DC feeding mode 1, which operates with DC power supply (terminal P/+, N/-), or DC feeding
mode 2, which normally operates with AC power supply (terminal R/L1, S/L2, T/L3) and with DC power supply
such as battery at power failure occurrence.
