14.6.7 Servo Analyze
Servo analyze is a tool for measuring frequency characteristics of the mechanical equipment.
Execute the servo analyze function to visually show the resonance point and anti resonance point of
the mechanical equipment, providing you with approximate measures of these parameter settings (anti
resonance frequency and notch filter relations).
During servo analyze operation, a torque is added three times. For this reason, the servomotor actually
moves. Note that the motor may turn substantially according to some vibration torque settings. (Enter a
suitable allowable stroke setting to set a limit.)
 Each setting
(1) Mode
In case of horizontally driven equipment, select "Normal." In case of vertically driven equipment,
select "UpDown."
(2) Notch filter
Select "Disable" to check mechanical characteristics such as the resonance point.
Select "Enable" to check effects of the notch filter.
(3) Adds vibration torque
Larger the value, better the accuracy. But the shock is larger, causing a larger burden to the
equipment. In regular cases, select the default setting (50%).
(4) Permission stroke
An error is caused if the servomotor moves beyond this reference value. A travel of the rotation
setting is not guaranteed.
