Pulse Train Output Of Output Power - Mitsubishi Electric FR-F820-00077 Instruction Manual

Parameters
5.8.13

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 0 kWh 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).
Fig. 5-110:
NOTES Because the accumulated data in the inverter is cleared when control power is lost by power fail-
ure 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 5-231.)
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.
