Nidec F600 - Setting PID Setpoint, Wake, and Sleep Thresholds; Auto Mode Operation and Sleep Verification

29 F600 Step By Step Guide
STEP 9: Running the drive in Auto mode
This section gives guidance on how to get running in Auto mode assuming the most common
application, a single pump application running with closed process PID loop to control pressure.
For alternative setups see the F600 User Guide.
It is assumed that the process feedback device is a 4-20 mA transducer which has been connected
to terminal 4 and 5 during Step 7 – Wire the drive control connections up.

feedback scaling.
Setup the PID Minimum Scaling Pr 0.030 and PID Maximum Scaling in Pr 0.031. By default,
the feedback is configured in percent where the range is 0.00 % to 100.00 %, where 100 %
= the feedback device maximum value e.g. for a 1 bar pressure sensor 100 % = 1 bar.
Note that all setpoints and feedback related parameters will use this scaling. The units of the
feedback and setpoint may be scaled into any unit type e.g. percent but on the display the
unit type will be shown as UU or User Unit.
Test the feedback
device.
Make sure it is safe to run the motor. Press and hold the green Hand button for 2 s or close
the Hand switch. The motor will turn at the Hand mode speed reference and the pump
software status changes to Hand Run.
Observe the PID1 Feedback Pr 0.067 and vary the Hand Mode Reference Pr 0.026. The
PID1 Feedback Pr 0.067 should increase with an increase in Hand Mode Reference
Pr 0.026.
If the feedback does not respond in proportion to the speed e.g. remains at 0. Please check
the configuration of the feedback device and wiring.
Find the frequency
or speed where flow
starts.
Observe the output of the application. Increase the Hand Mode Reference Pr 0.026 and
note the value when output flow is detected.
The resulting value should be entered as the Positive Minimum Reference Clamp Pr 0.023.
Stop the motor. Stop the Motor by pressing the red OFF / Reset button or by opening the Hand switch. The
pump software status changes to Off (Ready).
