+### 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 be ultimately limited by the `max_i_pos` and `max_i_neg` values, and will not exceed them.
+
+Set PID maximum output of channel 0 to 1.5 A.

+
+Set PID minimum output of channel 0 to 0.1 A.
+```
+pid 0 output_min 0.1
