9.2.4.9. Commands Description
GetFullStatus1
This command is provided to the circuit by the Master to get a complete status of the circuit and of the Stepper-
motor. The parameters sent via the 2-wire serial bus to the Master are:
• coil peak and hold currents value (Irun and Ihold)
• maximum and minimum velocities for the Stepper-motor (Vmax and Vmin)
• direction of movement clockwise / counter clockwise (Shaft)
• stepping mode (StepMode)
• acceleration (deceleration) for the Stepper motor (Acc)
• acceleration shape (AccShape)
• status information (see further)
• motion status <Motion [2:0]>
• over current flags for coil #1 <OVC1> and coil #2 <OVC2>
• digital supply reset <VddReset>
• charge pump status <CPFail>
• external switch status <ESW>
• step loss <StepLoss>
• electrical defect <ElDef>
• under voltage <UV2>
• temperature information <Tinfo>
• temperature warning <TW>
• temperature shutdown <TSD>
