！
• For the binary operation, idling time to wait for a
terminal input to be given can be set in the
multi-step input determination time [CA-55]. This
can prevent transition during terminal switching.
• Data are fixed after the time specified in [CA-55]
passes with no change in the input. Input response
would be slow if the determination time is set to be
large.
• For the command frequency of the 0th speed, the
command designated in the main speed selection
[AA101] is used. The left table is for [AA101]=07.
Ex.) 2nd speed is effective.
In this case we have [CA-06]=003 (CF1) and
[CA-07]=004 (CF2).
No assignment is made for 005 (CF3) and 006
(CF4).
Only the input terminal No. 7 (CF2) is ON.
