CommutationSearchCurrent Parameter

The CommutationSearchCurrent parameter specifies the level of current that the drive uses during the Commutation The action of steering currents to the proper motor phases to produce optimum motor torque/force. In brush-type motors, commutation is done electromechanically via the brushes and commutator. A brushless motor is electronically commutated using a position feedback device such as an encoder or Hall effect devices. Stepping motors are electronically commutated without feedback in an open-loop fashion. Search method to initialize the motor commutation The action of steering currents to the proper motor phases to produce optimum motor torque/force. In brush-type motors, commutation is done electromechanically via the brushes and commutator. A brushless motor is electronically commutated using a position feedback device such as an encoder or Hall effect devices. Stepping motors are electronically commutated without feedback in an open-loop fashion.. Refer to Commutation Search for more information.

The value of this parameter must be sufficiently high to overcome any friction or loading on the axis so that the motor can move freely during the initialization process.
