The PID function in the inverter
Depending on the type of feedback transducer used, the inverter can be setup for either 0-10V or a 4-20mA
feedback transducer.

9.3. EngineeringUnits(onlyforLCD)
The PID setpoint scaling can be selected with parameter 16-03 and 16-04.
Example: 0 – 200.0 PSI Setpoint, set 16-03 to 12000 (1 decimal, range 0 – 200) and 16-04 to 2 (PSI).
9.4. Sleep/WakeupFunction
The PID Sleep function can be used to prevent a system from running at low speeds and is frequently used in
pumping application. The PID Sleep function is turned on by parameter 10-29 set to 1. The inverter output turns
