Terminal functions are as follows. (Default setting)
Terminal S1 ··············· Input terminal function selection 5 (S1) = (S1)
Terminal S2 ··············· Input terminal function selection 6 (S2) = (S2)
Terminal S3 ··············· Input terminal function selection 7 (S3) = (S3)
Terminal RR/S4
········
Input terminal function selection 8 (S4) = (S4)
The RR/S4 terminal is set by default as an analog voltage input terminal. To use it as an input terminal for preset
speed operation, turn the SW3 switch to the S4 position.

3) Using other speed commands with preset speed command
When no preset speed command is issued, the inverter accepts an input command from the operation panel or
another analog input device.

The preset speed command is always given priority when other speed commands are input at the same time.
To use the RR/S4 terminal as an analog input terminal, turn the SW4 switch to the RR position. Note that this
makes it impossible to use the function assigned to S4.
