Terminal function assignment and data setting
Select multi-frequency (0 to 15 steps) -- SS1, SS2, SS4, and SS8
(Function code data = 0, 1, 2, and 3)㩷
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
(Multi-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 multi-frequency"
represents the reference frequency sourced by frequency command 1 (F01), frequency
command 2 (C30), or others. For details, refer to the block diagram in FRENIC-Multi User's
Manual, Chapter 4, Section 4.2 "Drive Frequency Command Block."

Select ACC/DEC time -- RT1 (Function code data = 4)㩷
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.
