7.5.7 Analog input feedback
Titan Go Servo Drive can also use analog feedback systems connected through the Communications and IOs
connector. From the voltage level of one analog input, the position or velocity of the rotor can be calculated. The
Titan Go have 1 differential analog input that can be used for feedback input, with a range of ±10 V. The input used
as feedback can be selected by software.

7.5.7.1 Potentiometer
Typically, a potentiometer is used as a postition feedback, providing a a voltage proportional to the rotor position.
The following picture shows how to connect a potentiometer as a position sensor using analog input 1:
7.5.7.2 DC tachometer
The Titan Go Servo Drive can use a DC tachometer for velocity feedback through the Communications and IOs
connector. A DC tachometer provides an analog signal whose voltage level is proportional to the rotor speed.

Recommended potentiometer resistance
Potentiometers with high values of resistance (> 10 k
Ω
) can result in non linear behavior due to its the
drive parallel input resistors. High resistance values also reduce the signal to noise ratio, making it easier
to have disturbances and reducing the quality of the measure.
However, a very small value of resistance may also consume too much power and cause self heating
(which causes additional variations on resistance). Therefore,
use the smallest value of resistance
that:
Does not exceed 1/2 of the potentiometer power rating (safety margin to prevent self heating).
Does not exceed the +5V_OUT current capacity.
Typically 1 k
Ω
to 10 k
Ω
will be preferred.
