Description
8 pin
A input
Set the voltage of A phase.
When output is DC, –10V ~ 10V voltage value to
set the voltage between negative full range and
positive full scale. When output is AC, 0-10V
voltage value to set the 0 to full scale.
9 pin
B input
Set the voltage of B phase.
When output is DC, –10V ~ 10V voltage value to
set the voltage between negative full range and
positive full scale. When output is AC, 0-10V
voltage value to set the 0 to full scale.
10 pin
C input
Set the voltage of C phase.
When output is DC, –10V ~ 10V voltage value to
set the voltage between negative full range and
positive full scale. When output is AC, 0-10V
voltage value to set the 0 to full scale.

Remote Control
Through the analog input interface, the analog signal can be input to remotely
set the output voltage value or power amplification function. For the detailed
function definition of the pin, please refer to the definition of the analog pins
description. The following is an example of amplitude modulation to introduce
how to connect and how to use.
When the voltage setting is controlled through the analog interface, the external
voltage (-10V ~ 10V) is connected to program the voltage value between 0 and
full scale(AC mode).
