About the inverter function
12.25.6 Outputting data with voltage/current
• As inverter information, I want to output
information externally with a voltage.
• As inverter information, I want to output
information externally with a current.
• With Analog output terminals Ao1 and Ao2, you
can select voltage output or current output by
operating Switches SW3 and SW4 on the
substrate.
Parameters
• For outputs of [Ao1] and [Ao2], voltage output has
an initial value in a range from 0 to 10 V, and
current output has an initial value in a range from 4
to 20 mA.
• Operate the switches on the substrate while the
inverter power supply is turned off.
• When [Cd-10]=01 is set, [FM], [Ao1], and [Ao2]
respectively perform outputs in accordance with
values of [Cd-15], [Cd-25], and [Cd-35].
Item Parameter Data Description

[Cd-10]
00 Invalid.
01
Valid. Outputs to terminals output
levels in the adjustment mode.
[Ao1] output filter
time constant
[Cd-21]
1~500[ms]
Filters and outputs the selected
data.
[Ao1] output data
type selection
[Cd-22]
00 Outputs the absolute value of data.
01 Outputs data with a symbol as is.
[Ao1] bias
adjustment
(Common to
voltage/current)
[Cd-23]
-100.0~100.0[%]
Biases data to adjust Point 0 of
data.
[Ao1] gain
adjustment
(Common to
voltage/current)
[Cd-24]
-1000.0~1000.0[%]
Apply a gain to data to adjust an
inclination in data.
[Ao1] output level in
the adjustment mode
[Cd-25]
-100.0~100.0[%]
Sets output in the adjustment
mode. It selects the maximum
output (at 100.0%), the minimum
output (at 0.0%) ([Cd-22]=00), or
the minimum output (at -100.0%)
([Cd-22]=01).
[Ao2] output filter
time constant
[Cd-31]
1~500[ms]
Filters and outputs the selected
data.
[Ao2] output data
type selection
[Cd-32]
00 Outputs the absolute value of data.
01 Outputs data with a symbol as is.
[Ao2] bias
adjustment
(Common to
voltage/current)
[Cd-33]
-100.0~100.0[%]
Biases data to adjust Point 0 of
data.
[Ao2] gain
adjustment
(Common to
voltage/current)
[Cd-34]
-1000.0~1000.0[%]
Apply a gain to data to adjust an
inclination in data.
[Ao2] output level in
the adjustment mode
[Cd-35]
-100.0~100.0[%]
Sets output in the adjustment
mode. It selects the maximum
output (at 100.0%), the minimum
output (at 0.0%) ([Cd-32]=00), or
the minimum output (at -100.0%)
([Cd-32]=01).
