AO1
AO1 is able to output analog voltage/current
(total 13 kinds of signals). Jumper JP4 (for jumper
terminal AO1) can select voltage or current ouput
mode, and voltage output is the default one. For
current output, just short the middle and another
pin with the jumper cap. AO2 can only provide
analog voltage output. See F6.21, F6.22.
(Reference ground: GND)
OUTPUT, 0~10V DC voltage.
Output voltage of AO1, AO2 came
from PMW waveform of CPU.
Output voltage is in direct
proportion to the width of PWM
waveform.

Power Port
+24V
24V is the common power for circuits of all digital
signal input terminals.
Maximum output current 200mA
▲
Control terminal AI1 can input both voltage and current signal, while AI2 can only input voltage signal; users can
conduct corresponding jumper on master control board according to signal type.
▲
Connecting week analog signal is easily affected by external disturbance. So wiring should be as short as possible.
The external control line should be set with isolating device or shielding line, and should be grounded.
▲
Input order signal line and frequency meter should be wired separately with shielding, and away from major loop
wiring.
▲
Control loop wiring should be over 0.75 mm
2
, and STP (shielded twisted pair) is recommended. The connecting part
of control loop terminals should be enameled with tin, or process metal joint with cold pressing.
▲
While connecting analog signal output devices, malfunction may occur because of interference from VFD, which can
be solved by fixing with capacitor or ferrite bead to the analog signal output device.
