Bit Operation
• Setting the Multi-function Input S1 to S7 Selection (C001 to C007) to 32 (SF1) to 38 (SF7) enables
the selection of the multi-step speed 0 to 7.
• Use the Multi-step Speed Reference 1 to 7 (A021 to A027) to set the frequency for SF1 to SF7.
• Use the 1st/2nd Frequency Reference Selection (A001/A201) to set the 1st/2nd Multi-step Speed
Reference 0 (A020/A220).
Set the 1st/2nd Frequency Reference Selection (A001/A201) to 02 (Digital Operator: F001) to enable
the 1st/2nd Multi-step Speed Reference 0 (A020/A220).
If A001/A201 are set to 01 (Control circuit terminal block: Analog input), the analog input is used as
the frequency reference to set the 1st/2nd Multi-step Speed Reference 0.
