If the actuator's current consumption rises above the set limit, the actuator regulates and tries to keep it
below the set current limit by reducing the PWM and therefore also the speed accordingly� The actuator
does this continuously until the actuator stops moving (mechanically blocked) - something that is determined
by monitoring the Hall feedback signal� If there are no changes to the Hall feedback signal during the set
time frame, the Integrated Controller will cut power to the H-bridge motor circuit�
If the actuator is stopped due to the above-mentioned criteria, it automatically drives slightly in the opposite
direction to reduce the torque in a blocking situation�

Current cut-offs

The principle behind the current cut-off measurement is an 'above limit' and a 'below limit' accumulating
counter� When the time-out counter reaches a specific value the current cut-off goes into effect� The time-
out value is pre-set at 200 ms�
