 Speed Selection Sequence Using Digital Inputs
If the digital inputs are used for speed selection, the speed selection method and the speed priority depends on
the setting of parameter d1-18.
Multi-Step Speed Operation 1/2 (Binary Input) (d1-18=0/3)
If d1-18 = 0
8 preset speed steps (defined in the parameters d1-01 to d1-08) can be selected using 3 binary coded digital
inputs. The Up/Down command starts the inverter. It stops when the Up/Down command is removed.
If d1-18 = 3
7 preset speed steps (defined in the parameters d1-02 to d1-08) can be selected using 3 binary coded digital
inputs. The Up/Down command starts the inverter. It is stopped when the Up/Down command is removed or
when no speed is selected (all D/Is off).
