Current Input
Input terminals, A1, A2, and A3 can accept a current input signal. Refer to
Table 4.18 for an example 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. To
use several speed references for a multi-step speed sequence, set the H1-oo parameters to 3, 4, 5, and 32. To assign the Jog
reference to a digital input, set H1-oo to 6.
