Monitor Display Selection For Terminals Fm And Am - Mitsubishi Electric 800 Series Instruction Manual

11.3

Monitor display selection for terminals FM and AM

For the standard model, monitored values are output in either of the following: analog voltage (terminal AM) in the AM type
inverters (FR-E800-4 and FR-E800-5) or pulse train (terminal FM) in the FM type inverter (FR-E800-1).
The signal (monitor item) to be output to terminal FM and terminal AM can be selected.

 Monitor description list (Pr.54, Pr.158)
• Set the type of monitor to be output through terminal FM (pulse train output) in Pr.54 FM terminal function selection.
Terminal FM is provided in the FM type inverter.
• 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 negative output, refer to
Terminal AM is provided in the AM type inverter.
