Output terminals for main circuit (U, V, W) :
Terminals [+1, +2] for connecting DC reactor, terminals [+1, +2/B1] for connecting brake
resistor:

Please use isolation wire or wire tube for power supply wiring and ground the
isolation layer or both ends of wire tube.

The output side of Hybrid Servo Controller cannot be connected with advance phase
capacitor, surge absorber, advance phase capacitor, or L-C and R-C filters.

These terminals are used to improve the power factor of DC reactor. There are
shorting plates on them when they leave the factory. Remove the shorting plates
before connecting the DC reactor.
For models with power ≥ 30kW (except VFD300VL43BXXXX) , there is no driver loop

for brake resistor inside. To increase the brake capability, please use an external
brake unit and brake resistor (both are optional).

Never short [B2] or [-] to [ ＋ 2/B1], which will damage the Hybrid Servo Controller.
