The three-phase power and energy measurement function PEMMXU calculates energy and power from the available current and voltage inputs. The function stores the accumulated values of the real and reactive energy in both directions, and presents these values as numerical and pulse outputs.
PEMMXU provides pulse outputs EAFPULSE, EARPULSE, ERFPULSE and ERRPULSE which are activated based on the calculated values of forward and reverse, active and reactive accumulated energy. The activation of the pulse depends on the Pulse quantity setting. For example, if Pulse quantity is set as "10000" Wh, EAFPULSE is activated every time accumulated energy EA_FWD_ACM increases by 10000 Wh. The pulse-on and -off time duration can be set using the Pulse on time and Pulse off time settings.
Instantaneous three-phase power and power factor measurements are available in monitoring data S_INST, P_INST, Q_INST and PF_INST.
