Pr.

Pr.

⋅ 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
.)

* The increments vary according to the inverter capacity. (55K or less/75K or

more)

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.

You can make the buzzer "beep" when you press key of the
operation panel (FR-DU07) and parameter unit (FR-PU04).

Contrast adjustment of the LCD of the parameter unit (FR-
PU04) can be performed.
Decreasing the setting value makes contrast light.

Set “1” in Pr.CL Parameter clear to initialize all parameters.
(Calibration parameters are not cleared.)*
Set “1” in ALLC All parameter clear to initialize all parameters. *
Set “1” in Er.CL Alarm history clear to clear alarm history. *
Parameter settings can be copied to multiple inverters by using
PCPY.

When parameters are copied to the 75K or more inverter from
the 55K or less inverter or vice versa, an

alarm appears on

the operation panel.
For the parameters whose setting range differ, set

Pr.989

as

below after reset.

* Parameters are not cleared when "1" is set in Pr.77 Parameter write selection.
