4.8 Use of AI Terminals
The CS200 provides two AI terminals (AI1 and AI2).
Terminal Input Signal Characteristic
AI1-GND It receives the signal of 0 to 10 VDC.
AI2-GND
If J8 jumps to the "V" position, the AI receives the voltage signal of 0 to 10 VDC.
If J8 jumps to the "I" position, the AI receives the current signal of 4 to 20 mA.
The AI allows the AC drive to use external voltage or current signal as the frequency reference setting channel or
the torque reference. The relationship between the voltage or current and the reference or feedback is dened in
b3.22 to b3.31.
The sampling value of the AI can be read in U0.12 and U0.13. The calculation value is for interal computation and
you cannot read it.
4.9 Use of AO Terminals
The CS200 provides one AO terminal (AO1). An extra of AO2 is provided by the extension card.
Terminal Output Signal Characteristic
AO1-GND
If J5 jumps to the "V" position, it outputs the signal of 0 to 10 VDC.
If J5 jumps to the "I" position, it outputs the signal of 0 to 20 mA.
AO2-GND It is provided by the extension card and outputs the signal of 0 to 10 VDC.
AO1 and AO2 can be used to indicate the internal running parameters. The indicated parameters can be dened by
b3.19 and b3.20.
The designated running parameters can be rectied before output. The rectication 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 b3.44 and b3.43.
