Group C3 Analog and Pulse Output
AO2 output function
(VSX Only)
HO output function
(VSX Only)
AO1 and AO2 are analog output terminals. Voltage output(0~10V) or current output(0~20mA) of
AO1 and AO2 can be selected through toggle switch AO1 and AO2.When used as high-speed pulse
output HO, Y2/HO terminal's functions are set in A0.11. Output range of HO pulse frequency is 0~
C3.09 (maximum output pulse frequency).
The ranges of corresponding digital output of AO1, AO2 and HO are as shown in the following
table.
0~2 times the rated current of inverter
0~2 times the rated voltage of motor
0~ 2 times the rated power
0~2 times the rated torque
Output values set by communication address 2005H
Output values set by communication address 2006H
When users need to change AO1 measuring range or correct the error of meter, it can be realized
by setting of C3.03 and C3.04. When using factory default set: 0~10V (or 0~20mA) of AO1
corresponds to “0~maximum”. By expressing standard output of AO1 as x, the adjusted AO1 output
as y, the gain as k, and the offset as b (100% of offset corresponds to 10V or 20mA), there is the
equation:
y=kx+b
Example:
Set C3.00 to 1: output frequency. Standard AO1 output: AO1 outputs 0V when output frequency is
0, and outputs 10V when output frequency is maximum frequency. If AO1 is requested to output 2V
when output frequency is 0.00Hz, and requested to output 8V when output frequency is the maximum
frequency. There is: 2=k*0+b; 8=k*10+b. Through these two equations, we obtain: k = 0.6, b = 2V, i.e.
C3.03 is set to 20.0% while C3.04 is set to 0.600.
Define output filtering time of AO1 terminal.

Adjustment method of AO2 output curve is the same as AO1.
