Data Sheet
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 three 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])>
