1.
On tool bar, click "Parameter(P)", and select "Mechanical Characteristics Analysis" option
2. In the mechanical characteristic analysis screen, loading torque can be selected, and the setting
range is 1%~100%. The user can search in different torque to increase the accuracy of search; the
loading torque is based on not damaging the machine as the standard, to estimate with different
loading torques, and the loading torque too low may not enable the machine to excite resonance,
the variation in the motor current feedback signal change is not large enough, causing the software
unable to calculate the accurate vibration frequency correctly. The error setting of resonance
frequency will cause the noise of the machine to become more severe. It is recommended that the
user can search for more than four times for each different loading torque, to increase the accuracy
and judgment of the frequency search.
3. After completing the setting of the loading torque, press
"Start"
and the driver will issue a high
frequency signal to the motor to capture the mechanical characteristics.
The following Figure is an example to explain: In the curve diagram, it can be found that there is a
low frequency resonance point around 34 Hz and there seems to be another resonance point at 459
Hz. The found resonance frequency can be input to the corresponding setting value according to
the frequency:
