6.10.4 Terminal AM calibration [C1 (Pr.901)]
By using the operation panel or parameter unit, you can calibrate terminal AM to full scale de-
flection.
The above parameter can be set when Pr. 160 = 0.
The parameter number in parentheses is the one for use with the operation panel (FR-PA02) for
the FR-E500 series or parameter unit (FR-PU04/FR-PU07).
The above parameters allow its setting to be changed during operation in any operation mode
even if "0" (initial value) is set in Pr. 77 "Parameter write selection".
Terminal AM gain calibration [C1 (Pr. 901)]
Terminal AM is factory-set to provide a 10V DC output in the full-scale status of the correspond-
ing 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 10V DC, the
maximum output current 1mA.
