    Encoderless stall detection uses an internal motor model for stall detection. Motors listed in Tables 4 and 5 work well with encoderless stall detection. Third-party motors may not work as well, as the algorithm is subject to constraints. National Instruments makes no guarantees of reliability of this feature when using third-party motors.
