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

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
(2)AM terminal calibration (C1(Pr.901))
⋅The AM terminal is
Pr. C2(902) to C7(905)

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.

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.
