19.6 AC400 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 SETPOINT, % 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 SETPOINT 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 SETPOINT and PID FEEDBACK displays are entered, the display will flash
SETPOINT or FEEDBACK before displaying the value to indicate which display is being
viewed.
