(1) Frequency monitoring reference( Pr. 55 )
(2) Current monitoring reference (
Pr. 56

For signal output, two different output terminals are available: analog current output terminal CA and analog
output terminal AM.
You can select the signals output to the terminals CA, AM.

The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)
* 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 .
• Set the full scale value when outputting the frequency monitor from
terminal CA or AM.
• For the calibration of terminal CA, set the full-scale value of the
connected meter when output current of terminal CA is 20mADC.
Set the frequency to be indicated as the full scale value on the meter
(20mADC ammeter) connected between terminal CA and 5. (For
example, 60Hz or 120Hz)
Output voltage is proportional to the frequency. (Maximum output
current is 20mADC.)
• For the calibration of terminal AM, set the full-scale value of the
connected meter when output voltage of terminal AM is 10VDC.
Set the frequency to be indicated as the full scale value on the meter
(10VDC voltmeter) connected between terminal AM and 5. (For
example, 60Hz or 120Hz)
Output voltage is proportional to the frequency. (Maximum output
voltage is 10VDC.)
• Set the full scale value when outputting the current monitor from
terminal CA or AM.
• For the calibration of terminal CA, set the full-scale value of the
connected current meter when the output current of terminal CA is
20mADC.
Set the current to be indicated as the full scale value on the meter
(20mADC ammeter) connected between terminal CA and 5.
Output current is proportional to the monitored value of output
current. (Maximum output current is 20mADC.)
• For the calibration of terminal AM, set the full-scale value of the
connected current meter when the output voltage of terminal AM is
10VDC.
Set the current to be indicated as the full scale value on the meter
(10VDC voltmeter) connected between terminal AM and 5.
Output voltage is proportional to the monitored value of output
current. (Maximum output voltage is 10VDC.)
