Inverter Wiring 11
It can conveniently control power-supply and power disconnection of the
inverter, and the power-on and power-off of the motor.
‹ AC reactor
1) To promote power factor;
2) To reduce harmonic input of the inverter against the grid;
3) Weaken influenced caused by unbalanced voltage of three-phase power
supply.
‹ Brake resistance
When the motor is at the dynamic braking status, it can avoid producing over
high pumping voltage in the DC loop.
