To further cover the PID Sleep function, the following is an example of the various parameter settings that could be
used. In this example the system will have the following specifications:
-
Max. Pump Motor Speed: 3600 RPM.
-
Set Point: 150 PSI.
-
Feedback Transducer Range: 0 – 200 PSI.
-
Pump System Sleep Level: 2160RPM or
60%
of max. speed set by
(P2-01=060.00).
Sleep Level Delay Time: 10 sec. set by
(P2-02=010.0 ).
-
Pump System Wakeup Level: 100 PSI
set by
(P2-03=0100).
Wakeup Time: 5 sec. set by
(P2-04=005.0).
Referring to
Step 3,
set the engineering units to
PSI
(
P1-01=02)
and then the range to 200
(P1-02=0200).
The following shows the keypad navigation sequence in setting the PID parameters.
NOTE: The inverter must be in the Stop mode in order to turn on the sleep function.
