PI feedback supervision (MPI)

Used to define the operating mode in the event of detection of a PI feedback lower than the limit set.

Once the variable pump is running at maximum speed (higher than HSP - AP0) and at the same time the PI feedback is lower than the

supervision threshold LPI - 2%, a time delay tPI is launched. If at the end of this time delay the value of the PI feedback is still lower than

the supervision threshold LPI + 3%, the drive switches to fallback mode as defined by parameter MPI.

- MPI = YES:

The drive will perform a freewheel stop and will display fault code SPI.

- MPI = LFF:

The drive will run at a fixed frequency LFF and will display fault code FrF.

In both cases the drive reverts to PI regulation mode as soon as the PI feedback is higher than the supervision threshold LPI + 3%.

In single variable with auxiliary pump mode (MdE = YES), the PI feedback supervision function is only active when both pumps are

operating.
