 Frequency monitor reference (Pr.55)
• Set the full-scale value for outputting the monitored items of output frequency, frequency setting value to the terminals CA
and AM.
• For the calibration of terminal CA, set the full-scale value of the connected meter when output current of terminal CA is 20
mA. Set the frequency to be indicated as the full scale value on the meter (20 mA DC ammeter connected between terminal
CA and 5; for example, 60 Hz or 120 Hz. Output current is proportional to the frequency. (The maximum output current is
20 mA DC.)
Output Current
20 mADC
• For the calibration of terminal AM, set the full-scale value of the connected meter when output voltage of terminal AM is
10 VDC. Set the frequency to be indicated as the full scale value on the meter (10 VDC voltmeter) connected between
terminal AM and 5. (For example, 60 Hz or 120 Hz) Output voltage is proportional to the frequency. (The maximum output
voltage is 10 VDC.)
