Use the wiring example shown in the figure above for any other analog input terminals. When using input A2 make sure DIP
switch S1 is set for voltage input.
Current Input
Input terminal A2 can accept a current input signal. Refer to
Table 4.7 to set terminal A2 for current input.

Switching between Main/Auxiliary Frequency References
The frequency reference input can be switched between the analog terminals A1, A2, and A3 using multi-speed inputs. Refer
to Multi-Step Speed Selection on page 168 for details on using this function.
