“D” Group: Monitoring Functions
You can access important parameter values with the “D” Group monitoring functions,
whether the inverter is in Run Mode or Stop Mode. After selecting the function code
number for the parameter you want to monitor, press the Function key once to show the
value on the display. In functions D005 and D006, the intelligent terminals use
individual segments of the display to show ON/OFF status.
If the inverter display is set to monitor a parameter and powerdown occurs, the inverter
stores the present monitor function setting. For your convenience, the display
automatically returns to the previously monitored parameter upon the next powerup.
