Stall Detection and Position Control for Microstepping Motordrivers
The AMIS-3062x and NCV70627 are single-chip microstepping motordrivers with position controller and control/diagnostic interfaces for building dedicated mechatronics solutions that connect remotely with a LIN or I2C master. Integrated sensorless stall detection prevents the positioner from losing steps and stops the motor when running into stall, enabling silent, yet accurate position calibrations during a referencing run. This application note describes the stall detection operation and how it can be used to enable the development of high reliable sensorless steppermotor applications.
