4.8.6 )requency Closed-Loop Control
The MD380 has a built-in PID regulator. Together with the frequency sources, the PID
regulator can implement automatic adjustment of progress control, such as constant
temperature, constant pressure, and tension control.

The MD380 has two built-in equivalent PID calculating units. You can set the features,
such as adjustment speed and accuracy, for the two units separately based on the actual
conditions. Switchover between the two units can be implemented automatically or by
means of an external DI terminal.
