4.2.3 Autotuning
No experience required to achieve optimum settings.
The Servopack contains a built-in autotuning function to automatically measure the machine
characteristics and set the user constants.
Servo drives normally require tuning to match the machine configuration and rigidity. This
tuning requires a great deal of experience and is difficult for a person unfamiliar with the tun-
ing procedure.
However, autotuning allows even totally inexperienced people to easily complete the tuning.
