Baldor MN1851 manual

GV–GainThis 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.

1.Click in the “Proportional Gain (GV)” box. Enter a value for GV. You may want to begin with the default values – click on the “default” button and answer “yes”.

Note: The default values may not be best for all applications, it may be too high. If 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”.
