evc/epc Controller

With SAE J1939 Interface

When the measured rpm increases to above 1900rpm, the evc/epc will reduce the current to maintain 1900rpm

until it reaches 0.

The closed loop control is a dynamic process. The evc/epc constantly changes the current to maintain the

reference rpm.

If the overshoot of the speed is big, the changing rate of the current is fast.

If the overshoot of the speed is small, the changing rate of the current is slow.

The same working principle applies when different signals are used as the reference and the feedback.
