•In the following multi-function input settings, if you allocate a function to one code (C001 to C006),
the same function will be allocated to the other code (C201 to C206) automatically.
08: 2nd control, 11: Free run, 12: External trip, 18: Reset, 19: Thermistor input,
23: PID enabled/disabled, 53: Special 2nd function
•"08: 2nd control" and "53: Special 2nd function" cannot be allocated simultaneously. If you attempt
to do so, the terminal where you last allocated the function takes precedence. The previous data
is set to "255: No allocation", and the terminal function is disabled.
Multi-step Speed Operation Function
•You can set RUN speeds using codes and switch between the set speeds via the terminal.

2nd multi-step speed reference 0
A021 Multi-step speed reference 1

A032 Multi-step speed reference 12
A033 Multi-step speed reference 13
A034 Multi-step speed reference 14
A035 Multi-step speed reference 15
* To switch to the 2nd multi-step speed reference 0, allocate 08 (SET) to the multi-function input and then turn it
on.
•By allocating 02 to 05 (CF1 to CF4) to multi-function inputs, you can select multi-step speeds 0 to
15.
Note that multi-step speed terminals not allocated to any multi-function input are regarded as
"OFF". (e.g., if 02 (CF1) and 03 (CF2) are allocated to multi-function inputs, the available multi-step
speeds are 0 to 3.)
•For speed 0, you can change the frequency reference with the frequency reference selection
(A001). (e.g., if the frequency reference is set to the control terminal block (terminal, A001: 01), you
can change it via input terminals FV and FI.)
•For speed 0, use A020/A220 if the frequency reference is set to the Digital Operator (A001: 02).
•Use A021 to A035 to set frequencies for speeds 1 to 15.
