Chapter 4 Explanation of Functions
(1) Binary operation mode
Assign functions "02" (CF1) to "05" (CF4) individually to the terminal [1] to [8] functions (C001 to C008) to
make multispeed s 0 to 15 available for selection.
Specify the desired frequencies for speeds 1 to 15 by setting multispeeds 1 to 15 (A021 to A035).
You can set speed 0 by using function "A020", "A220", "A320", or "F001" (see Section 4.2.1) when you
have specified the digital operator for the frequency source setting. You can set speed 0 by using the O, OI,
or O2 terminal when you have specified the control circuit board for the frequency source setting.

- With multispeed binary operation mode, you can use the multistage speed/position determination time
setting (C169) to specify a delay to be set until the relevant terminal input is determined. Use this
specification to prevent the application of fluctuating terminal input before it is determined.
- The input data is finally determined when terminal input becomes stable after the delay set as C169.
(Note that a long determination time deteriorates the input terminal response.)
Determination time (C169) = 0

- Assign functions "32" (SF1) to "38" (SF7) individually to the terminal [1] to [8] functions (C001 to C008) to
make multispeed s 0 to 7 available for selection.
- Specify the desired frequencies for speeds 1 to 7 (SF1 to SF7)
by setting multispeeds 1 to 7 (A021 to A027).

If two or more input terminals are turned on at the same
time, the terminal given the smallest terminal number
among them has priority over others. The "X" mark in the above table indicates that the speed can be
selected, regardless of whether or not the corresponding terminal is turned on.
