7. Tuning At the time of shipping, with the combination of the galvano motor and controller (GC-201), appropriate
servo tuning has been completed.
The following tools have been prepared to check malfunctions during use, and handling trouble such
as mirror damage.
• Control software
It is possible to check servo tuning related parameters and make changes from the control
software’s Servo Setting tab.
Note: Changes are not usually made to the parameters. Settings with inappropriate parameter
values can cause abnormal operations such as oscillations.
• Frequency characteristic (FFT) measurement
It is possible to check the servo tuning status.
(See 7.2 Frequency Characteristic (FFT) Measurement for details)
• Auto tuning
When adjusting servo tuning, in order to exchange a damaged mirror, an easy auto tuning
program is required.
However, use of this function is limited to the mirror shape provided by the setting file (definition
file).
(See 7.3 Easy Auto Tuning for details)
• X and Y axis matching
This function automatically matches the step movement response waveform of Axis 1, and Axis 2.
