1.6 Reactor
1.6.1 Input AC Reactor
For MD200 series drives with power greater than 1kW, an AC reactor should be connected at the input power terminals to reduce the
current harmonics, to be able to comply with the limits of IEC 61000-3-2 and IEC 61000-3-12 standards. For more information about the
suitable AC reactor, consult your agent of Inovance.
The sensitivity of a single-phase AC reactor shall be greater than 8 mH to meet the IEC 61000-3-12 standard.
The sensitivity of a three-phase AC reactor shall be greater than 5 mH to meet the IEC 61000-3-12 standard .
1.6.2 Output Reactor
When the motor output cable is longer than 100 meters, the rising edge of pulse wave generates a reected voltage at motor terminals
due to the mismatch of characteristic impedance of the motor and cable. The reected voltage is superposed to the high voltage square
wave pulse, producing stress to stator winding insulation, which causes sustained greater heat loss and higher partial discharge pulse
due to high-frequency harmonics, resulting in a rapid failure of motor insulation under PWM pulse voltage.
Therefore, when the motor output cable is longer than 100 meters, install a reactor at the output terminals.
