(M) Monitor display and monitor output signal
Monitor description list (Pr.52, Pr.774 to Pr.776)
• Set the monitor to be displayed on the operation panel and the parameter unit in Pr.52, Pr.774 to Pr.776.
• Refer to the following table to find the setting value for each monitoring. The value in the Pr. setting column is set in each of
the parameters for monitoring (Pr.52, Pr.774 to Pr.776) to determine the monitor item. The value in the RS-485 column is
used for the RS-485 communication special monitor selection. The value in the MODBUS RTU column is used for the
MODBUS RTU real time monitor. (The items marked with "—" cannot be selected. The circle in the negative indication (-)
column indicates that the indication of negative signed numbers is available.)
