Actual value is the actualvalue of inverter. After PC/PLC receives the parameter value, it will divide the correspondingcoefficient to get the actual value.NOTE: Take no account of radix point of the data in the data package when PC/PLC transmitscommand to inverter. The valid value is range from 0 to 65535.www.comoso.com
