7.5 Reference of the terminal CA (analog current output) and AM (analog
voltage output) (Pr. 55, Pr. 56, Pr. 866, Pr. 867, Pr. 869)
Two types of monitor output, analog current output from the terminal CA and analog voltage output from the
terminal AM, are available.
Set the reference of the signal output from terminal CA and AM.

terminal CA and AM.
0 to 5s Set the output filter of terminal AM.
0 to 5s Adjust response level of current output.
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 current 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.
