4.16.3 Reference of the terminal CA (analog current output) and AM (analog voltage
output) (Pr. 55, Pr. 56, Pr. 866, Pr. 867, Pr. 869)
(1) Frequency monitoring reference ( Pr. 55 )
(2) Current monitoring reference ( Pr. 56 )
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.

77 Parameter write selection .
• Set the frequency to be referenced when the frequency monitor
(output frequency/set frequency) is selected for the terminal CA and
terminal AM display.
• Set the frequency when the current output at terminal CA is
20mADC.
The analog current output and inverter output frequency at terminal
CA are proportional. (The maximum output current is 20mADC.)
• Set the frequency (output frequency/set frequency) when the voltage
output at terminal AM is 10VDC.
The analog voltage output and frequency at terminal AM are
proportional. (The maximum output voltage is 10VDC.)
• Set the current to be referenced when the current monitor (inverter
output current, etc.) is selected for the terminal CA and terminal AM
display.
• Set the current value when the current output at terminal CA is
20mADC.
The analog current output and current value at terminal CA are
proportional. (The maximum output current is 20mADC.)
• Set the current value when the voltage output at terminal AM is
10VDC.
The analog voltage output and current value at terminal AM are
proportional. (The maximum output voltage is 10VDC.)
