AutoMsetAngle Parameter
Default Value: 90
Minimum Value: 0
Maximum Value: 359
Units: degrees
Type: int
IMPORTANT: This parameter applies only when you use the Auto-MSET 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. for AC brushless motors that do not have Hall-effect switches.
The AutoMsetAngle parameter specifies the electrical angle that the drive outputs during the Auto-MSET method to initialize 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 Automatic Motor Set (Auto-MSET) for more information.
Aerotech recommends that you change the value of this parameter only if the motor starts commutation The action of steering currents to the proper motor phases to produce optimum motor torque/force.

Stepping motors are electronically commutated without feedback in an open-loop fashion. from a known electrical angle and you want to control the direction of motion. If these conditions do not apply to your project settings, keep this parameter at the default value of 90°.
The specified electrical angle is the orientation to which the motor travels within an electrical cycle. But because multiple electrical cycles usually occur during one revolution of the motor, the motor might travel to a different orientation based on its initial position. For example, if four electrical cycles occur during one revolution of the motor, then there are four possible orientations to which the motor shaft can travel.
