Analog I/O Settings
This section describes the analog I/O signal settings for this inverter.
7-3-1
Analog Input Function Selection
This inverter has two types of analog input terminals, a current input and a voltage input. The analog
input terminal [AI1] has a voltage input only. Analog input terminal [AI2] can be switched between cur-
rent input (factory default setting) and voltage input and used by Analog input selector switch (SW3).
Analog input terminal [AI1] 0 to 10 V, -10 to 10 V
Analog input terminal [AI2] (AII) 4 to 20 mA, 0 to 20 mA
Analog input terminal [AI2] (AIV) 0 to 10V
• For details on analog input adjustment, refer to 7-3-2 Analog Input Adjustment Function
on page
7-38.
• One function is allocated to an analog input terminal. One input cannot be used simultaneously for
another function.
•
If the same function is selected at the analog input terminal [AI1] function selection and analog input
terminal [AI2] function selection, the signal from the input terminal [AI1] is given priority.
