High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• Setting the Multi-function Input S1 to S8 Selection (C001 to C008) to 02 (CF1) to 05 (CF4) enables
the selection of the Multi-step Speed Reference 0 to 15.
• Use the Multi-step Speed Reference 1 to 15 (A021 to A035) to set the frequency for the 1st to 15th
multi-step speeds.
• 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.
• For multi-step speed binary operation, the wait time until the inverter recognizes terminal input can be
set in the Multi-step Speed/Position Determination Time (C169). This prevents the transitional status
before terminal input is recognized from being accepted.
•
Input data will be determined if it remains unchanged for the time set in the Multi-step Speed/Position
Determination Time (C169). Note that setting a long determination time results in a slow input response.
