Apply conditions of Auto tuning<br />
The Servo drive provides Auto tuning and uses an advanced control technique “ON-LINE” to measure the<br />
Load Inertia Ratio to control the system to achieve default speed or Position Response Bandwidth.<br />
System must <strong>com</strong>ply with the conditions below, so that the Auto tuning can operate normally.<br />
(1) The timing from stop to 2000rpm needs be less than 1 second.<br />
(2) Motor speed is larger than 200rpm.<br />
(3) Load Inertia needs be 100 times less than the inertia of the motor.<br />
(4) External force or the variation of inertia ratio can not be excessive.<br />
Rigidity Setting<br />
When Auto tuning is used, set the Rigidity Level depending on the various Gain settings for applications<br />
such as those listed below:<br />
