4.10.9 Pulse train output of output power (Y79 signal, Pr. 799)
(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 activation of retry function or at an automatic restart after
instantaneous power failure (power failure that is too short to cause an inverter reset). It does not clear the output
power.
⋅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).
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).
Parameter
Number Name Initial
Value Setting Range Description
799 Pulse increment setting for
output power 1kWh 0.1kWh, 1kWh, 10kWh,
100kWh, 1000kWh
Pulse train output of output power (Y79) is output in
pulses at every output power (kWh) that is specified.
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)
....Specifications differ according to the date assembled. Refer to page 400 to check the SERIAL number.
CAUTION
⋅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 electr icity bill.
⋅Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection) may affect the other functions. Please set
parameters after confirming the function of each terminal. (Refer to page 128)
REMARKS
⋅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.
When Pr.799 = 10
