When setting parameters, refer to the instruction manual (applied) and understand instructions.
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).
 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, Pr.192 (Output terminal
function selection) .
Without connecting an IPM motor, the frequency movement can
be checked by the monitor or analog signal output.
Two types of operation can be selected using this parameter: an
actual operation by connecting an IPM motor, or a test operation
without connecting an IPM motor to simulate a virtual operation.
Manual adjustment of gain is useful to exhibit the optimum
performance of the machine or to improve unfavorable conditions
such as vibration and acoustic noise during the operation with high
load inertia or gear backlashes.

Speed control P gain
(Pr.820)
The proportional gain during speed control is set. Setting this
parameter higher improves the trackability for speed command
changes. It also reduces the speed fluctuation due to a load
fluctuation.
 Speed control integral time (Pr.821)
The integral time during speed control is set.
Setting this parameter lower shortens the return time to the original
speed when the speed fluctuates due to a load fluctuation.
Parameters you can use for your own purposes.
You can input any number within the setting range 0 to 9999.
For example, the number can be used:

As a unit number when multiple units are used.

As a pattern number for each operation application when
multiple units are used.

As the year and month of introduction or inspection.
