0: Digital setting (b0.02)
When the inverter is powered on, the value of b0.02 is taken as the master frequency source.
1: Keypad potentiometer (When using LED keypad)
2: Analog input AI1
AI1 and AI2 are (0
~
10V) voltage input and (0
~
20mA) current input programmable. Voltage or
current input can be selected through toggle switches AI1 and AI2 on control board.
When using external voltage/current analog input to the drive, the connection diagram is shown
as Fig. 6-2:

If 10V power supply inside the drive is used with potentiometer, the connection diagram is shown
as Fig. 6-3. Note that the toggle switch should be switched to voltage input side.

3: Communication
Upper computer is the master frequency command source of the drive through standard RS485
communication interface on the drive. Refer to Group H0 and appendix on this manual for further
information about communication protocol, and programming, etc.
4: Multi-reference
In multi-reference mode, combinations of different DI terminal states correspond to different set
frequencies. The VS Series supports a maximum of 16 speeds implemented by 16 state combinations
of four DI terminals (allocated with functions 13 to 16) in Group C0. The multiple references indicate
percentages of the value of b0.08 (Maximum frequency).
If a DI terminal is used for the multi-reference function, you need to perform related setting in
group C0.
5: PLC
Master frequency command is determined by simple PLC. See parameter Group F1 for details.
6: Process PID output
Master frequency command is determined by process closed-loop PID computation result. See
parameter Group F0 for details.
7: DI7/HI pulse input
If this parameter value selected, command frequency will be determined by pulse frequency input
via terminal DI7/HI only. In such a case, A0.09 should be set to 1. Corresponding relation between
pulse frequency and command frequency is specified in C2.32
