4.11.9 Pulse train output of 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, 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
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 201)
(1) 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).
Pulse output of output power
⋅ 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 page 140)
⋅ When parameter copy is performed, Pr.799 = "9999" might be set. However, the inverter operates as Pr.799 were at "1kWh"
(initial value) in such case.
