Figure 6-17 Operating procedures for mechanical characteristic analysis
NOTE
◆
To avoid strong vibration during test, set the current excitation to 10% during initial execution.
◆
The analysis waveform may be distorted if the current excitation is too small.
◆
If the vibration generated during the test cannot be eliminated by reducing the current excitation, the
possible causes and solutions are as follows:
1) The gain is too high. Reduce the speed gain or set the notch based on the auto-tuned resonance
point.
2) The inertia is too large. Set a correct inertia.
◆
After setting the notch, the waveform under mechanical characteristic test mode is the same with that
before the setting, but the speed closed loop and open loop modes will be attenuated.
