9.3.3 Voltage Output (-10 – +10V) Using an I/O Expansion Module
If the optional I/O expansion module is installed, the operating status can be monitored using
the bipolar voltage output of the I/O expansion module.

Voltage Output (-10 – +10 V) Details
Code Description
OUT-14 AO3
Mode
The output mode can be set identically to when the AO1 voltage output is used.
However, because bipolar voltage output is possible for AO3, unipolar (0
– +10V) or
bipolar (-10 – +10V) voltage can be produced according to the type of the output
variable.
Examples of bipolar output voltages are as follows.

The graph below illustrates how the analog voltage output (AO3) changes
depending on the OUT-15 (AO3 Gain) and OUT-16 (AO3 Bias) values.
The Y-axis is analog output voltage (-10
– +10V), and the X-axis is a percentage of the
output. For example, if the maximum frequency set at DRV-20 (Max Freq) is 60 Hz
and the present output frequency is 30 Hz, then the x-axis value on the next graph is
50%.
