Procedure for Achieving Optimum Performance

Step 1: Start the motion test by clicking Start/Stop button. Find a resonance speed by slightly
moving the slider bar of internal pulse generator back and forth. See Figure 16.
Figure 16: Anti-resonance tuning
Step 2: Run the motor at the resonance speed and verify the motor smoothness. You may
find a better smoothing value by slightly moving the slider bars of AMP(s) and Phase(s) back
and forth.
It is very important to make the AMP(s) and Phase(s) adjustments at the proper test speeds
with an unloaded motor. Running at an incorrect test speed will not excite the motor at its
peak resonance, making it more difficult to find proper adjustment values. Optimum AMP(s)
