• Shown below are the multi-speed table for binary
operation (when [Ab-03] = 00) and that for bit
operation (when [Ab-03] = 01).
Table for binary operation

Exemplar operation
Example (1) If the multi-speed 3rd speed is engaged
and the revolution is accelerating, the
enabled acceleration time is the
multi-speed 3rd speed acceleration time
[AC-38].
Table for bit operation
[Ab-03] = 01; Input terminal function 007 [SF1] to
013 [SF7]
Example (2) If the multi-speed 1st speed is engaged
and the revolution is decelerating, the
enabled deceleration time is the
multi-speed 3rd speed deceleration time
[AC-40] for the multi-speed 3rd speed
that has been engaged until the
multi-speed 1st speed is engaged.
