Understand why the AMC board needs a setpoint timeout of 300 ms instaed of 100 ms

[valegagge]

Following the test done here #627 we noticed that the AMC boards require a setpoint timeout of 300 ms instead of 100 ms as the EMS.

We need to investigate the cause.

We know the cause of this difference between the boards
