Functions
With multi-step speed binary operation, the wait time until the terminal input is determined can
be set using Multi-step Speed/Position Determination Time (C169) (set value × 10 ms =
Determination time). This prevents the transition status before input establishment from being
applied.
If no input is made during the time set in C169, the data is determined.
Note that the longer the determination time, the slower the input response.
Bit Operation
Selection of multi-step speed references 0 to 7 becomes possible when SF1 to SF7 (32 to 38)
are allocated to Multi-function Input Selections (C001 to C007).
Use Multi-step Speed References 1 to 7 (A021 to A027) to set the frequencies for SF1 to SF7.
Multi-step speed operation is given priority over Frequency Reference Selection (A001). However,
the frequency reference 0 conforms to the setting of Frequency Reference Selection (A001).
When several terminals are simultaneously turned on, priority is given to the terminal with the
smallest number.
The × mark in the above table means that speed is selected regardless of ON/OFF status.
