Adjustment Of Terminal Fm And Am (Calibration); Buzzer Control Of The Operation Panel; Pu Contrast Adjustment; Parameter Clear, Parameter Copy - Mitsubishi Electric FR-F700 Manual

⋅ The following gives the items which can be monitored by the
cumulative saving power 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.)

and AM (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 and AM.
(1) FM terminal calibration (C0(Pr.900))
⋅ The terminal FM is preset to output pulses. By setting the
Calibraton 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.

*1 Not needed when the operation panel (FR-DU07) or parameter unit (FR-
PU04) is used for calibration.
Used when calibration must be made near the frequency meter for such a
reason as a remote frequency meter.
However, the frequency meter needle may not deflect to full-scale if the
calibration resistor is connected. In this case, use this resistor and
operation panel or parameter unit together.
(2) AM terminal calibration (C1(Pr.901))
⋅ The AM terminal is factory-set to output 10VDC in the full-
scale state of each monitor item. By setting the calibration
parameter C1 (Pr. 901), the ratio (gain) of the output voltage
can be adjusted to the meter scale. Note that the maximum
output voltage is 10VDC.
