Monitor Display Selection For Terminals Fm/Ca And Am - Mitsubishi Electric FR-F820-00046 Instruction Manual

5.8.3 Monitor display selection for terminals FM/CA and
AM
The monitored statuses can be output as the following items: analog voltage (terminal AM), pulse train (terminal FM) for the
FM type inverter, analog current (terminal CA) for the CA type inverter.
The signal (monitor item) to be output to terminal FM/CA and terminal AM can be selected.

 Monitor description list (Pr.54, Pr.158)
• Set Pr.54 FM/CA terminal function selection for monitoring via terminal FM (pulse train output) or terminal CA (analog
current output).
• Set Pr.158 AM terminal function selection for monitoring via terminal AM (analog voltage output). Negative signals can
be output via terminal AM (in the range of -10 to +10 VDC). The circle in the [Negative output (-)] column indicates that the
output of negative signals is available via terminal AM. (To enable or disable the output of negative signals, refer to
288.)
• Refer to the following table and select the item to be monitored. (Refer to

Description
Select the item monitored via terminal FM or CA.
Select the item monitored via terminal AM.
Set the full-scale value when outputting the frequency
monitor value to terminals FM, CA and AM.
Enter the full-scale value of a meter which corresponds to
the output via terminal FM/CA or terminal AM to monitor
the output current.
Enter the full-scale value of a meter which corresponds to
the output via terminal FM/CA or terminal AM to monitor
the motor torque.
Set the availability of negative signals output via terminal
AM, to the operation panel, and through communication.
