Multi-step Speed Operation Function
•You can set RUN speeds using codes and switch between the set speeds via the terminal.
•For multi-step speed operation, you can select either 4-terminal binary operation (with 16 steps
max.) or 7-terminal bit operation (with 8 steps max.).
* To switch to the 2nd/3rd control, allocate 08 (SET)/17 (SET3) to the desired multi-function input and then turn it
on.
•During multi-step speed operation, if frequency reference selection A001 is set to the terminal (01),
and the external analog input (O, O2, OI) setting mode based on a combination of O/OI selection
A005, O2 selection A006, and the AT terminal is set to "reversible", the RUN command is inverted
when "main frequency reference +
auxiliary frequency reference" is less than zero.
