Mitsubishi Electronics FR-F700 Pr PU contrast adjustment, Parameter clear, parameter copy

⋅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.)

Pr. C0(900), C1(901)	Adjustment of terminal FM
	and AM (calibration)
C0(Pr.900) FM terminal calibration	C1(Pr.901) AM 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.

Pulse cycle T2: Set with Pr. 55 (frequency monitor)

Set with Pr.56 (current monitor)

*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.

Pr. C2(902) to C7(905) Refer to the section about Pr. 125, Pr. 126

Pr. 989 Parameter for manufacturer setting. Do not set.

Pr. 990 Buzzer control of the operation panel

Pr.990 PU buzzer control

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

Pr.990 Setting	Description
0	Without buzzer

Pr. 991 PU contrast adjustment

Pr.991 PU contrast adjustment

Contrast adjustment of the LCD of the parameter unit (FR- PU04) can be performed.

Decreasing the setting value makes contrast light.

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.
