2) Changing Motor Speed

The motor speed for operation under Digital Operator control can be changed with a fol-
lowing user constant.
User Constant: Cn-10 (JOGSPD), Units: r/min., Standard setting: 500
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.
