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.

If the
[

option is not assigned to any
intelligent input terminal, then inverter
recognizes
[
AT
]
= OFF in following table.
Combination of A005 setting and

Be sure to set the frequency source setting
A001=01 to select the analog input terminals.
Example (default input configuration shown
for –FU models; –FE models require input
configuration—see

):
See I/O specs on
page 4–6.
NOTE
:
You cannot use both the
[
O
]
and
[
OI
]
inputs at the same time on the X200
inverter.
