PID control macro
The ACS355 solar pump drive is designed to work with MPPT algorithm. Hence the PID
control macro is disabled and similarly when the PID control macro is enabled, the MPPT
algorithm is disabled.
See section PID control macro in ACS355 user’s manual (3AUA0000066143[English]).
Pump cleaning
The solar pump inverter provides the pump cleaning function to prevent solids from
building up on pump impellers or piping. The function consists of a programmable
sequence of forward and reverse runs of the pump to shake off any residue on the impeller
or piping.
