<div class="markdown_content"><p>Anyone else out there able to get this example to work properly? Is there any other way to use PWM with CodeSys? I really only need to set my server to 2 different positions and don't really need any of the soft motion functionality.</p></div>

<div class="markdown_content"><p>Hello all,<br/> I am using the Softmotion Servo example as instructed but I cannot get any more than the 60 to -60 degrees of motion to work. I try to set the servo config to 90 to -90 but it doesn't work. I have verified that these servos can actually move 90 to -90 with python PWM code.</p> <p>Thanks in advance.</p></div>
