Terminal function assignment and data setting
Select multistep frequency (0 to 15 steps) --
SS1
,
SS2
,
SS4
, and
SS8
(Function code data = 0, 1, 2, and 3)
The combination of the ON/OFF states of digital input signals
SS1
,
SS2
,
SS4
and
SS8
selects one of
16 different frequency commands defined beforehand by 15 function codes C05 to C19 (Multistep
frequency 0 to 15). With this, the inverter can drive the motor at 16 different preset frequencies.
The table below lists the frequencies that can be obtained by the combination of switching
SS1
,
SS2
,
SS4
and
SS8
. In the "Selected frequency" column, "Other than multistep frequency"
represents the reference frequency sourced by frequency command 1 (F01), frequency command
2 (C30), or others.

(Function code data = 4)
This terminal command switches between ACC/DEC time 1 (F07, F08) and ACC/DEC time 2
(E10, E11).
If no
RT1
command is assigned, ACC/DEC time 1 (F07, F08) takes effect by default.
