Beschreibung
Zusammenfassung:	An apparatus and method for monitoring and controlling motor current during a dispensing of material from a dispensing tool (10) is provided, including a method for measuring the motor current of the dispensing tool during operation through a motor controller (U2). The method further includes sending a feedback signal from the motor controller (U2) relating to the measured motor current to an input of a microcontroller (U1) that is adapted to a dispensing tool (10). The feedback signal is compared to a prescribed threshold and the motor current is conditioned based on the comparing of the feedback signal to the prescribed threshold.
