AMIS-30623 LIN Microstepping Motordriver
Data Sheet
Motion Qualification Mode
This mode is useful to debug motion parameters and to verify the stability of stepper motor systems. The motion qualification mode is
entered by means of the LIN command
TestBemf.
The SWI pin will be converted into an analogue output on which the Bemf integrator
output can be measured. Once activated, it can only be stopped after a POR. During the Back emf observation, reading of the SWI
state is internally forbidden.
More information is available in the white paper “Robust Motion Control with AMIS-3062x Stepper Motor Drivers”.
