Pulse Train Output Of Output Power (Y79) Signal (Pr. 799) - Mitsubishi Electric FR-D720-0.2K-G Instruction Manual

4.11.9 Pulse train output of output power (Y79) signal (Pr. 799)

After power ON or drive unit reset, output (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).

(1) Pulse increment setting for output power (Y79 signal, Pr. 799)
After power ON or drive unit reset, output (Y79) signal is output in pulses every time accumulated output power of

the drive unit exceeds Pr. 799 Pulse increment setting for output power.
 The drive unit 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 drive
unit 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 Pr. 190 or Pr. 192

(Output terminal function selection).

NOTE
 Because the accumulated data in the drive unit is cleared when control power is lost by power failure or at an drive unit
reset, the value on the monitor cannot be used to charge electricity bill.
 Changing the terminal assignment using Pr. 190 and Pr. 192 (output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal. (
