Du/Pu, Terminal Fm/Am Monitor Display Selection (Pr. 46 To Pr. 48, Pr. 50, Pr. 52, Pr. 54) - Mitsubishi Electric FR-HC2-7.5K Instruction Manual

Description of parameters

3.4.13 DU/PU, terminal FM/AM monitor display selection (Pr. 46 to Pr. 48, Pr. 50, Pr. 52, Pr. 54)

The monitor to be displayed on the main screen of the operation panel (FR-DU07-CNV)/parameter unit (FR-PU07) can
be selected.
In addition, signals to be output from the terminal FM (pulse train output) and AM (analog voltage output) can be
selected.

Description
Set "0" to clear the watt-hour meter monitor.
Set the maximum value in the range of 0 to
9999kWh for the monitoring from communication
Set the maximum value in the range of 0 to
65535kW for the monitoring from communication.
Displays the numbers of times that the
cumulative energization time monitor exceeded
65535h. Reading only
Set the number of times to shift the cumulative
power monitor digit.
The monitor value is clamped at the maximum
value.
No shift
The monitor value is cleared when it exceeds the
maximum value.
Select the monitor output to terminal AM.
Select the monitor to be displayed on the
operation panel and parameter unit.
Refer to the following table for monitor
description.
Select the monitor output to terminal FM.
