Pulse train output of output power

After power ON or inverter reset, output signal (Y79 signal) is output in pulses every time accumulated output
power, which is counted after the Pr.799 Pulse increment setting for output power is set, reaches the specified value
(or its integral multiples).

Pulse increment setting for output power (Y79 signal, Pr.799)
• After power ON or inverter reset, output signal (Y79 signal) is output in pulses every time accumulated output power of the
inverter exceeds Pr.799 Pulse increment setting for output power.
• The inverter continues to count the output power at retry function or when automatic restart after instantaneous power
failure function works without power OFF of output power (power failure that is too short to cause an inverter reset), and it
does not reset the count.
• If power failure occurs, output power is counted from 0kWh again.
• Assign pulse output of output power (Y79: setting value 79 (positive logic), 179 (negative logic)) to any of Pr.190 to Pr.196
(Output terminal function selection).
NOTE
• Because the accumulated data in the inverter is cleared when control power is lost by power failure or at an inverter reset, the
value on the monitor cannot be used to charge electricity bill.
• Changing the terminal assignment using Pr. 190 to Pr. 196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal. (Refer to
• In an application where the pulse outputs are frequently turned ON/OFF, do not assign the signal to the terminal ABC1 or
ABC2.
Otherwise, the life of the relay contact decreases.
