Operation, Display and Application Examples
3.10 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 define the function of the DO terminals by setting P5-01 and P5-05 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 P5.

When P5-00 = 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 defined by P5-06.
3.11 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.

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

It receives the signal of 0–10 VDC.
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 4–20mA.
