• Multi-Step Speed 2
When setting terminal A3's analog input to Multi-Step Speed 2, set H3-06 (Terminal A3 Function Selection) to 2
(Auxiliary frequency reference 1). When setting d1-02 (Frequency Reference 2) to Multi-Step Speed 2, set H3-06 to F
(Through mode).
• Multi-Step Speed 3
When setting terminal A2's analog input to Multi-Step Speed 3, set H3-10 (Terminal A2 Function Selection) to 3
(Auxiliary frequency reference 2).
When inputting 0 to 10 V to terminal A2's analog input, set H3-09 to 0, and DIP switch S1 on the control circuit
terminal board to V (voltage).
The different speed references can be selected as shown in
selection.
