4.9 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 define the function of the DO terminals by setting P5-01 and P5-04 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.
Terminal Corresponding Function Code Output Feature Description
FM-CME
P5-06 when P5-00 = 0
Transistor, able to output high-speed pulses 10 Hz to
100 kHz; drive capacity: 24 VDC, 50 Ma
P5-01 when P5-00 = 1 Transistor; drive capacity: 24 VDC, 50 Ma
TA-TB-TC P5-02 Relay; drive capacity: 250 VAC, 3 A
DO1-CME P5-04 Transistor; drive capacity: 24 VDC, 50 mA
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.
4.10 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.
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.
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 defined by P4-13 to
P4-27.
Figure 4-30 Defining corresponding relationship of the voltage or current and actual
setting or feedback
The sampling of AI terminals can be queried in D0-09 to D0-11. The calculation value is
for internal subsequent calculation and cannot be directly read by the user.
4.11 Use of AO Terminals
The AC drive supports a total of two AO terminals, among which AO1 is provided by the
control board.
