PARAMETERS
Description of parameters
(2) AM terminal calibration (C1 (Pr. 901))
Calibrate the AM terminal in the following procedure.
1) Connect a 0 to 10VDC meter (frequency meter) across converter terminals AM and 5. (Note the polarity. The
terminal AM is positive.)
2) Refer to the monitor description list (page 86) and set Pr. 50.
When you selected a monitor that needs full-scale setting (Pr. 50 = "1 to 3, 5, 7"), preset power supply frequency or
current that outputs 10V signal using Pr. 49, Pr. 51, Pr. 53, Pr. 55, and Pr. 56 .
(3) How to calibrate the terminal FM when using the operation panel (FR-DU07-CNV)
Terminal AM is initially-set to provide a 10VDC output in the full-scale
status of the corresponding monitor item. Calibration parameter C1 (Pr. 901)
allows the output voltage ratios (gains) to be adjusted according to the
meter scale. Note that the maximum output voltage is 10VDC.
REMARKS
When outputting a signal such as input current, which cannot be adjusted to 100% easily by an operation, set Pr. 50 = "21"
(reference voltage output) for the calibration. 10VDC is output from the terminal AM.
REMARKS
Calibration can be performed during operation.
