Bit Operation
• Setting the Multi-function Input S1 to S8 Selection (C001 to C008) to 32 (SF1) to 38 (SF7) enables
the selection of the 0th to 7th multi-step speed.
• Use the Multi-step Speed Reference 1 to 7 (A021 to A027) to set the frequency for SF1 to SF7.
• For the Multi-step Speed Reference 0, set the Frequency Reference Selection (A001).
To enable the 1st/2nd/3rd frequency reference 0 setting, set A001 to 02 (Digital Operator: F001).
If this parameter is set to 01 (Control circuit terminal block: Analog input), the frequency reference for
the Multi-step Speed Reference 0 is set via analog input.
