TMC222 DATASHEET (V. 1.12 / March 7, 2011)
Copyright 2004-2011 TRINAMIC Motion Control GmbH & Co. KG
6.8
Command Description
There are data fields labeled as "N/A = not applicable". Within the command description tables, the
contend is normally given as '1'. Data fields labeled by N/A might be reserved for later variants of the
TMC222 and the content should be ignored for the TMC222.
Concerning response datagrams, the byte 0 is the slave address that is applied for addressing, where
the byte 1 is the slave address that is sent back within the response data frame.
6.8.1
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 two wire serial bus to the Master are:
coil peak and hold current values (Irun and Ihold)
maximum and minimum velocities for the stepper-motor (Vmax and Vmin)
direction of motion clockwise / counterclockwise (Shaft)
stepping mode (StepMode) (Table 11: StepMode on page 21)
acceleration (deceleration) for the Stepper motor (Acc)
acceleration shape (AccShape)
status information:
motion status <Motion [2:0]>
over current flags for coil A <OVC1> and coil B <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>
