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 Search method to initialize the motor commutation for AC brushless motors that do not have Hall-effect switches.

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.
