5.1.10 Motor Shutdown Management
The TMC222 is set into motor shutdown mode as soon as one of the following condition occurs:
The chip temperature rises above the thermal shutdown threshold Ttsd. See 5.1.12 Temperature
Management on Page 15
The battery voltage drops below UV2 See 5.1.13 Battery Voltage Management on Page 16.
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.
During motor shutdown the following actions are performed by the main controller:
H-bridges are set into high impedance mode
The target position register TagPos is loaded with the contents of the actual position register
ActPos.
The two-wire-serial-interface remains active during motor shutdown. To leave the motor shutdown
state the following conditions must be true:
Conditions which led to a motor shutdown are not active anymore
A GetFullStatus1 command is performed via serial interface.
Leaving the motor shutdown state initiates the following
H-bridges in Ihold mode
Clock for the motor control digital circuitry is enabled
The charge pump is active again
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.
