The sampling of AI terminals can be queried in U0-09 to U0-11. The calculation value is for
internal subsequent calculation and cannot be directly read by the user.
4.13 Use of AO Terminals
The AC drive supports a total of two AO terminals, among which AO1 is provided by the
control board and AO2 is provided on the extension card.
Terminal Output Signal Characteristic
AO1-GND
If J5 is connected to the position with "V" mark, it outputs the signal of 0–10 VDC.
If J5 is connected to the position with "I" mark, it outputs the signal of 0–20 mA.
AO2-GND It is provided on the extension card and outputs the signal of 0–10 VDC.
AO1 and AO2 can be used to indicate the internal running parameters in the analog mode.
The property of indicated parameters can be defned by P5-07 and P5-08.
The designated running parameters can be rectified before output. The rectification feature
is Y = kX + b, among which "X" indicates the running parameters to be output, and "k" and
"b" of AO1 can be set by P5-10 and P5-11.
