Analog Input Current/Voltage Select
The [AT] terminal selects whether the inverter uses the voltage [O] or current [OI]
input terminals for external frequency control. When intelligent input [AT] is ON, you
can set the output frequency by applying a current input signal at [OI]-[L]. When the
[AT] input is OFF, you can apply a voltage input signal at [O]-[L] to set the output
frequency. Note that you must also set parameter A001 = 01 to enable the analog
terminal set for controlling the inverter frequency.

Notes:
• If the [AT] option is not assigned to any
intelligent input terminal, then inverter
recognizes [AT] = OFF in following table.
• Be sure to set the frequency source setting
A001=01 to select the analog input terminals.
Combination of A005 setting and [AT] input for analog input activation.
Note that you cannot give [O] and [OI] input at the same time on X200 inverter.
