19.6 MC1000 DISPLAY IN PID MODE
When the drive is in PID mode, the DRIVE STATUS portion of the display will indicate
actual output frequency (in Hertz) instead of RUN, and the right side of the display
will indicate PID SET POINT, % LOAD, or PID FEEDBACK. The ENTER key is
used to toggle between the different displays. Examples of the possible displays
are shown below:

In the examples above, the drive is running at 42.53 Hz to maintain the PID SET
POINT of 35.0 psi. Pressing the ENTER key displays % LOAD, which is 57%.
Pressing ENTER again displays the PID FEEDBACK from the process, which is
33.7 psi.
When the PID SET POINT and PID FEEDBACK displays are entered, the display
will flash SET POINT or FEEDBACK before displaying the value to indicate which
display is being viewed.
