Monitor display and monitor output signal

3.10.3 CA, AM terminal function selection (Pr.55, Pr.56, Pr.867, Pr.869)

For signal output, two different output terminals are available: analog current output terminal CA and analog
Pr.54
output terminal AM.

The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 146)
* 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.

(3) Terminal AM response adjustment (Pr.867)
• Using Pr. 867, the output voltage response of the terminal AM can be adjusted within the range 0 to 5s.
• Increasing the setting stabilizes the terminal AM output more but reduces the response level. (Setting "0" sets
the response level to 7ms)
(4) Adjustment of response level of terminal CA (Pr.869)
• The response level of the output current of the terminal CA can be adjusted between 0 and 5s with Pr. 869.
• Increasing the setting stabilizes the terminal CA output more but reduces the response level. (Setting "0" sets
the response level to about 7ms.)

• 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.)
