ABB REG670 - Function Block

energy values are available as output signals and also as pulse outputs. Integration of
energy values can be controlled by inputs (STARTACC and STOPACC) and EnaAcc
setting and it can be reset to initial values with RSTACC input.
The maximum demand for active and reactive powers are calculated for the set time
interval tEnergy and these values are updated every minute through output channels.
The active and reactive maximum power demand values are calculated for both
forward and reverse direction and these values can be reset with RSTDMD input.
