SDC2130, Hall sensor and Linak Actuator

8 years 1 month ago #29527311 by marcusbarnet
Hello,

as you suggested , I\'ve bought three Linak actuators to use them with my two SDC2130 controllers.

What I need is to avoid the actuator to reach some positions: for example, actuator does not have to reach its maximum and minimum lenght since it has to work only in a 10%-90% of its range.

Each actuator comes with an Hall sensor and these are the specifications.

Even if I\'ve carefully read the SDC2130 user manual, I\'m not able to understand how to perform the correct connections between the Hall sensor and the controller.
I have two signal wires: where is it supposed to connect them? Do I have to connect them in controller analog inputs? or I have to use digital or pulse input?

I have to setup the motor to work in closed loop?

You must connect to an analog input.

But because the input range is 0-5V and the hall output is higher, you must add two resistors to form a voltage divider. You also must insert a 1uF capactitor between the ground pin and the analog input pin to filter noise.

The max hall output voltage is the power supply voltage.

Then look at the manual on how to configure the input as position feedback and how to set its min and max range.

Note that it is not ideal that the hall sensors give an output that is higher than 5V. Ideally, you should have used an actuator that uses 5V for the hall power supply. This way, you could have used the 5V output from the 15-pin connector.
