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.
Setting 2: Serial Communications
This setting requires entering the frequency reference via the RS-485/422 serial communications port (control terminals R+,
R-, S+, S-).
To setup the drive to receive the “Auto Setpoint” from serial communication, set b1-01 to “2: Serial Com,” and connect the
RS-422/RS-485 serial communications cable to terminals R+, R-, S+, and S- on the control I/O terminal block. Refer to
153 to see the connection diagram using a PC to provide the auto setpoint reference to the drive.
