Set the motor speed (JOG speed) in this user
constant when motor is operated using the digital
operator.
Set the motor speed (JOG speed) in this user constant when motor is operated using the
digital operator.
For details about setting the motor speed, refer to 4.1.5 Operation in User Constant Set-
ting Mode and Appendix D List of User Constants.
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.
