line, and 100% of pulse input corresponding setting corresponds to the maximum
frequency of F0-10, as shown in Figure 4-22.

4.8.6 Frequency 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.

selection) must be set to 8 (PID). The PID-related parameters are set in group FA, as shown
in Figure 4-23.
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.
