Chapter 5 Function parameter
136
The inverter's multifunction output DO will output ON signal when the inverter's
operating frequency is in a certain range of target frequency
This parameter is used to set the frequency arrival detection range, the parameter is the
percentage of maximum frequency. The above figure is the schematic diagram of frequency
arrival.
