12.25.6 Outputting data with voltage/current
Ｑ
• As inverter information, I want to output
information externally with a voltage.
• As inverter information, I want to output
information externally with a current.
Ａ
• With Analog output terminals Ao1 and Ao2, you
can select voltage output or current output by
operating Switches SW3 and SW4 on the
substrate.

！
• 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].
