### PID output clamping
|
||||||
|
|
||||||
|
It is possible to clamp the PID algorithm output independently of channel output limits. This is desirable when e.g. there is a need to keep the current value above a certain threshold in closed-loop mode.
|
||||||
|
|
||||||
|
Note that the actual output will still ultimately be limited by the `max_i_pos` and `max_i_neg` values.
