The following gives the items which can be monitored by the cumulative
power saving monitor (Pr. 52 = "51").
(The cumulative power monitor data digit can be shifted to the right by the
number set in Pr. 891 Cumulative power monitor digit shifted times.)
When setting parameters, refer to the instruction manual (applied) and understand instructions.

C0(900)
Adjustment of terminal FM (calibration)
C0(Pr.900) FM terminal calibration
The operation panel and parameter unit can be used to calibrate
the full scales of the terminals FM.
FM terminal calibration (C0(Pr.900))

The terminal FM is preset to output pulses. By setting the
Calibration parameter C0 (Pr. 900), the meter connected to the
inverter can be calibrated by parameter setting without use of a
calibration resistor.

Using the pulse train output of the terminal FM, a digital display
can be provided by a digital counter. The monitor value is 1440
pulses/s output at the full-scale value of Pr. 54 FM terminal function
selection.

 Not needed when the operation panel or parameter unit (FR-PU07) is
used for calibration. Use a calibration resistor when the indicator
(frequency meter) needs to be calibrated by a neighboring device
because the indicator is located far from the inverter. However, the
frequency meter needle may not deflect to full-scale if the calibration
resistor is connected. In this case, perform calibration using the
operation panel or parameter unit.
