You can access important system 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 D05 and D06, the intelligent termi- nals use individual segments of the display to show On/Off status.
