3.5.3 Mechanical system diagnostic measurement procedure
The resonance point of the machine connected to the servomotor can be measured.
The procedure is described below.
NOTE: This function is for servo drive AD2 only. It does not properly work for models
earlier than AD2.
1- Make preparations as directed below:
Before making measurements, exercise the parameter setup function to set the
parameters as shown in the following table:
Parameter name No. Setting Initial value
Moment of inertia Fd-00 Enter an approximate value. Motor-specific value
Speed control cut-off frequency Fd-01 5 to 10Hz 30Hz
Torque command filter time constant Fd-06 0ms 2ms
Notch filter bandwidth 1 Fd-13 0dB 0dB
Notch filter bandwidth 2 Fd-15 0dB 0dB
2- In the opening window, click the [Test Run and Adjustment (T)] button. The
following window then opens. Click the Machine Diagnosis tab.
This function is for servo drive AD2 only. It does not properly work for models
