Load Inertia
The anti-resonance feature is most effective if the load inertia is set precisely. If this is a known
value, the rst option circle should be clicked, the inertia entered, and units of measurement
selected. If the exact inertia is not known, the second option circle should be selected and an ap-
proximate load to motor inertia ratio entered. This number can be adjusted as needed.
Dening a Motor not in the Recommended List
When a Custom Motor is used, detailed information from the manufacturer will be needed. This
includes electrical specications (holding torque, rated current and rotor inertia) as well as a wiring
diagram. To dene a Custom Motor, that circle should be checked and the Dene Custom Motor
button clicked. In the Add New Motor dialog box, current, torque and inertia values are entered.
For the smoothest motion, the harmonic distortion gain and phase should be entered. This may
need to be determined by running the motor at a slow speed (1 rev/sec) with different gain and
phase values until the desired effect is achieved. If the values are not known or determined, gain
and phase may be set at 0.
