GV- -Gain This is the "proportional gain" of the velocity loop. It controls the gain of the
velocity loop by adjusting the controls response to the error. The error is the
difference between the commanded and actual velocity. The higher the gain, the
smaller the difference (or error). The adjustable range is from 0 to 32767.
Note: The default values may not be best for all applications, it may be too high. If

may want to begin with the default values – click on the "default" button
and answer "yes".
the system is noisy (displays an audible noise) decrease this value
immediately.
To obtain a faster rise time, increase the GV--gain setting. The ramp up
time (to operating speed) will be faster. As you increase the value for
GV, the system may have very large overshoots and become unstable.
Decrease the GV value immediately. Then decrease it another 10%.
2. Next, verify that the value you entered provides adequate system
response. You can check this out, by having the software move the
equipment and plot the response. Proceed to "Plotting of Move".
