GetFullStatus2
This command is provided to the circuit by the Master to get the actual position of the Stepper-motor. The
position is provided by the circuit in 16-bit format, with the 3 LSBs at ‘0’ when in half stepping mode (StepMode
= “00”). Furthermore programmed target position and secure position are also provided.
Notations:
• actual position of the stepper motor <ActPos [15:0]>
• target position of the stepper motor <TagPos [15:0]>
• secure position of the stepper motor <SecPos [10:0])>
