Commutation is the means by which a servo drive controls the torque of a motor by determining the position of the motor and applying current to the appropriate motor phases.  If the rotor position of the motor is not determined correctly or the motor power phase wires are wired to the wrong terminals, the drive will apply current to the wrong phase at the wrong time (or at the wrong rotor position).  This will cause the motor to run away or lock up.
