AMIS-30623 LIN Microstepping Motordriver
ResetToDefault
This command is provided to the circuit by the LIN master in order to reset the whole slave node into the initial state. ResetToDefault
will, for instance, overwrite the RAM with the reset state of the registers parameters (See
LIN master to initialize a slave node in case of emergency, or simply to refresh the RAM content.
Note: ActPos and TagPos are not modified by a ResetToDefault command.
Important: Care should be taken not to send a ResetToDefault command while a motion is ongoing, since this could modify the
motion parameters in a way forbidden by the position controller.
ResetToDefault corresponds to the following LIN writing frames (type #1).
RunVelocity
This command is provided to the circuit by the LIN Master in order to put the motor in continuous motion state.
Note: Continuous LIN communication is required. If not Lost LIN is detected and an autonomous motion will start. See also
behavior.
RunVelocity corresponds to the following LIN writing frames (type #1).

If broad = ‘0’ all the circuits connected to the LIN bus will reset to default
If broad = ‘0’ all the stepper motors connected to the LIN bus will start continuous motion.
