4.11 Use of DO Terminals

The control board provides three DO terminals, namely FM, DO1 and TA/TB/TC. FM and

DO1 are transistor outputs and can drive 24 VDC low-voltage circuit; TA/TB/TC is relay

output, and can drive 250 VAC control circuit.

You can obtain another two terminals DO2 and PA/PB/PC by installing an I/O extension

card. DO2 is transistor output and PA/PB/PC is relay output.

You can dene the function of the DO terminals by setting F5-01 and F5-05 to indicate the

running state and alarm information of the AC drive. There are a total of 40 functions. For

details, see the descriptions of group F5.

Terminal Corresponding Function Code Output Feature Description

FM-CME

F5-06 when F5-00 = 0

Transistor, able to output high-speed pulses 10 Hz

to 100 kHz; drive capacity: 24 VDC, 50 mA

F5-01 when F5-00 = 1 Transistor; drive capacity: 24 VDC, 50 mA

TA-TB-TC F5-02 Relay; drive capacity: 250 VAC, 3 A

PA-PB-PC F5-03 Extension card, relay; drive capacity: 250 VAC, 3 A

DO1-CME F5-04 Transistor; drive capacity: 24 VDC, 50 mA

DO2-CME F5-05

Extension card, transistor; drive capacity: 24 VDC,

50 mA

When F5-00 = 0, the FM terminal is high-speed pulse output. The frequency of output

pulses indicates the value of the internal running parameters. The greater the value is, the

higher the output pulse frequency is. The 100% value corresponds to 100 kHz. The property

of the indicated internal parameter is dened by F5-06.

4.12 Use of AI Terminals

The AC drive supports a total of three AI terminals, among which AI1 and AI2 are provided

on the control board and AI3 is provided on the extension card.

Terminal Input Signal Characteristic

AI1-GND It receives the signal of 0–10 VDC.

AI2-GND If J8 is connected to the position with "V" mark, it receives the signal of 0–10 VDC.

If J8 is connected to the position with "I" mark, it receives the signal of 4–20 mA.

AI3-GND It is provided on the extension card and receives the signal of -10 to +10 VDC.

As external voltage/current signal, AI is used for frequency source setting, torque setting,

voltage setting at V/F separation, and PID setting or feedback. The corresponding relationship

of the voltage or current and actual setting or feedback is dened by F4-13 to F4-27.
