(1) Procedure for Custom Tuning
Use the following procedure to execute custom tuning when the tuning mode is set to 0 (set servo gains with
priority given to stability).
Be sure to carefully read the SigmaWin+ Operation Manual before executing this function.
Special care must be taken for the following.
• Before executing this function, make sure that the emergency stop (power off) can be activated when
needed.
When tuning is initiated by this function, some parameters will be overwritten with the recommended values. As a
result, the response speeds may change considerably. Before executing this function, make sure that the emergency
stop (power off) can be activated when needed.
• Set a correct moment of inertia (mass) ratio to execute this function.
If not correctly set, vibration may be generated.
• If you change the feedforward level, the new setting is not used immediate. It is used after the completion
of positioning.
1.
Confirm that the correct moment of inertia ratio in Pn103 is set by using the advanced
autotuning.
