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
terminal calibration" can also be set in the external operation mode.
•C1 is factory-set to 1mA full-scale or 1440 pulses/s FM output frequency at 60Hz. The
maximum pulse train output of terminal FM is 2400 pulses/s.
•When a frequency meter is connected to across terminals FM-SD to monitor the running
frequency, the FM terminal output is filled to capacity at the factory setting if the maximum
output frequency reaches or exceeds 100Hz. In this case, the Pr. 55 setting must be changed
to the maximum frequency.
•When the FR-PU04 is used, make calibration with Pr. 900.
POINT
By setting the Pr. 54 "FM 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.
At 1440 pulses/s, the meter generally deflects to full-scale.
