YASKAWA A1000 Series

Multi-Step Speed Selection
To use several speed references for a multi-step speed sequence, set the H1-oo parameters to 3, 4, 5, and 32. To assign the
Jog reference to a digital input, set H1-oo to 6.
Notes on using analog inputs as Multi-Speed 1, 2, and 3:
• Multi-Step Speed 1
Set b1-01 to 1 to set terminal A1 analog input to Multi-Step Speed 1.
Set b1-01 to 0 when setting d1-01, Frequency Reference 1, to Multi-Step Speed 1.
• Multi-Step Speed 2
Set H3-06, Terminal A3 Function Selection, to 2 (Auxiliary Frequency Reference 1) when setting terminal A3 analog input
to Multi-Step Speed 2.
Set H3-06 to F (Through mode) when setting d1-02, Frequency Reference 2, to Multi-Step Speed 2.
• Multi-Step Speed 3
Set H3-10, Terminal A2 Function Selection, to 3 (Auxiliary Frequency Reference 2) when setting terminal A2 analog input
to Multi-Step Speed 3.
Set H3-10 to F (Through mode) when setting d1-03, Frequency Reference 3, to Multi-Step Speed 3.
Set H3-09 to 0 and set DIP switch S1 on the control circuit terminal board to V (voltage) when inputting 0 to 10 V to terminal
A2 analog input.
Select the different speed references as shown in Table 4.12. Figure 4.23 illustrates the multi-step speed selection.
