Function assignment of external terminal and control
4.11.9 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 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)
.
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).

0.1kWh, 1kWh, 10kWh,
100kWh, 1000kWh
Output signal is output in pulses at every output
power (kWh) that is specified.
The above parameters can be set when
Pr. 160 Extended function display selection
= "0".
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.
