(2) Bit operation (max. 8-speed command:
[Ab-03]=01)
• Multi-step speeds of 0th to 7th speeds can be
chosen by assigning 007-013 ([SF1]-[SF7]) to the
input terminals 1-9, A, and B [CA-01]-[CA-11].
• The frequency setting of [SF1]-[SF7] should be
made to the multi-step speeds of 1st to 7th speeds
([Ab-11]-[Ab-17]).

• If multiple terminals are made ON simultaneously,
the one with smaller number has priority. “-” in the
table indicates that a frequency is chosen
independently from ON/OFF state of the terminals.
• For the command frequency of the 0th speed, the
command designated in the main speed selection
[AA101] is used. The following table is for
[AA101]=07.
Ex.) 2nd speed is effective.
In this case we have [CA-06]=007 (SF1) and
[CA-07]=008 (SF2).
No assignment is made for 009 (SF3) and 013
(SF7).
Only the input terminal No. 7 (SF2) is ON.
If SF1 becomes ON in this state, the 1st speed
becomes effective.
