(4) Speed setting signal (current) bias/gain adjustment method
Follow the following procedure to adjust the bias and gain of the speed setting voltage (current) using the operation
panel. Refer to page 173 for the details of parameters.
(a) Method to adjust any point by application of a voltage (current) across terminals 2 and 5 (4 and 5).
