6.6 Power Supply Filters
6.6.11 Harmonic Suppression
IEC 61800-3-2 specifies limits on the amounts of conducted harmonic emissions (current) from electrical
equipment connected back into the electricity supply.
The drive has two terminals P1 and P2 across which a user may place an inductor (choke) to limit emissions for
compliance to the standard above or simply to ensure a cleaner local supply. Note that by increasing the size of
the choke the conducted emissions will be less, but the power output available may drop. If an inductor is placed
between terminals P1 and P2 on X2, it shall be designed to drop less than 5% of the line voltage

If no choke is to be used, a suitable link must be installed at P1 and P2 on provided connector to
power the motor
At 3A rms on the AMD2000 3A, 10mH of inductance is required. A suitable device may be Hammond
Manufacturing 159J.
AS 61000-3-2 defines equipment over 1kW for use in industrial environments as Professional Equipment, and
there is no requirement by the standard for the user to limit the conducted harmonic current emissions. As the
minimum power output of the AMD 9 is over 1kW ANCA Motion does not recommend an inductor for this
purpose, however if a user wishes to reduce harmonics for better local mains supply condition then an inductor
no greater than 10mH for a three phase AC (supply side not armature side) line reactor is recommended. Note
that the power output from the drive will decrease as the inductor size increases. However the drive will have
reduced stress on the bus capacitors, resulting in a longer lifespan.
