CommutationSearchTime Parameter
Default Value: 2
Minimum Value: 2
Maximum Value: 10
Units: time milliseconds
Type: int
IMPORTANT: This parameter applies only when you use 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.

The CommutationSearchTime parameter specifies the quantity of time that the drive continues to use the level of current that is specified by the CommutationSearchCurrent parameter. Refer to Commutation Search for more information.
Aerotech recommends that you keep this parameter at a low value in the range of 2 - 3 milliseconds. A higher value does not make initialization more accurate and it will cause the axis to move during the initialization process.
