Page 19: Chapter 4. Description Of Operation
In operation, the driver compares the milliamp input signal with the voltage signal derived from the potentiometer and runs the stepper motor to the position in which the milliamp signal corresponds with the feedback signal. This results in a speed setting proportional to the milliamp signal. Figure 4-1. Cover Assembly Woodward... -
