Speed Selection Sequence Using Digital Inputs - Omron VARISPEED L7 Manual

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.
Parameter
No.
d1-18 Speed Priority Selection
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).
