Terminal function assignment and data setting
Select multistep frequency--(SS1), (SS2), and (SS4)
(Function code data = 0, 1, and 2)㩷
Switching digital input signals (SS1), (SS2), and (SS4) ON/OFF may switch the present set
frequency to those defined by function codes C05 through C11 (multistep frequencies). With
this, the inverter may drive the motor at 8 different preset speeds.
The table below lists the frequencies that can be obtained by the combination of switching
(SS1), (SS2), and (SS4). In the column "Selected frequency," "Other than multistep frequency"
represents the set frequencies defined by frequency command 1 (F01), frequency command 2
(C30), and others. For details, refer to the block diagram in Chapter 4, Section 4.2 "Drive
Frequency Command Generator."

Digital input signal (RT1) assigned to the specified terminal ON/OFF may switch combinations
between acceleration/deceleration time 1 (defined by function codes F07 and F08) and
acceleration/deceleration time 2 (defined by E10 and E11).
Turning (RT1) ON, for example, enables the inverter to drive the motor using acceleration/
deceleration time 2.
