Introduction
Select the Multi-Step Speed Control Application in menu M5. See Chapter 5 of the 9000X AF
Drives User Manual.
The Multi-Step Speed Control Application can be used in applications where fixed speeds are
needed. Totally 15 + 2 different speeds can be programmed: one basic speed, 15 multi-step
speeds and one jogging speed. The speed steps are selected with digital signals DIN3, DIN4,
DIN5 and DIN6. If jogging speed is used, DIN3 can be programmed from fault reset to jogging
speed select.
The basic speed reference can be either voltage or current signal via analog input terminals
(2/3 or 4/5). The other one of the analog inputs can be programmed for other purposes.
