5.2 Adjustment (Calibration) of the Frequency Meter

(Indicator)

Changing example Deflecting the meter (analog indicator) to full-scale (across

FM-SD: 1mA, across AM-5: 5V) at the preset frequency of

60Hz. (Refer to page 22 for frequency setting)

POINT

• The calibration parameters "C1" can be made to be read by setting "1" (extended

function parameter valid) in Pr. 30 "extended function display selection".

• Set the value of the calibration parameter C1 "FM (AM) terminal calibration".

Remarks

• Depending on the set value, it may take some time for the needle to move.

• If "1" is set in Pr. 30 "extended function display selection", the calibration parameter

C1 "FM (AM) terminal calibration" can also be set in the external operation mode.

POINT

By setting the Pr. 54 "FM (AM) terminal function selection" value, preset Pr. 55

"frequency monitoring reference" or Pr. 56 "current monitoring reference" to the

running frequency or current value at which the output signal is 1440 pulses/s (5V).

At 1440 pulses/s (5V), the meter generally deflects to full-scale.
