5.1.10 Motor Shutdown Management
The TMC222 is set into motor shutdown mode as soon as one of the following condition occurs:
•
•
•
•
During motor shutdown the following actions are performed by the main controller:
•
•
The two-wire-serial-interface remains active during motor shutdown. To leave the motor shutdown
state the following conditions must be true:
•
•
Leaving the motor shutdown state initiates the following
•
•
•
Now the TMC222 is ready to execute any positioning command.
IMPORTANT NOTE:
First, a GetFullStatus1 command has to be executed after power-on to activate the TMC222.

An electrical problem occurred, e.g. short circuit, open circuit, etc. In case of such an problem
flag <ElDef> is set to one.
Chargepump failure, indicated by <CPFail> flag set to one.
H-bridges are set into high impedance mode
The target position register TagPos is loaded with the contents of the actual position register
ActPos.
Conditions which led to a motor shutdown are not active anymore
A GetFullStatus1 command is performed via serial interface.
