GotoSecurePosition
This command is provided by the I
2
C master to one or all the steppermotors to move to the secure position
SecPos[10:0]
. See the
priority encoder
description for more details. The priority encoder table also acknowledges the cases where a
GotoSecurePosition
command will be ignored.

HardStop
This command will be internally triggered when an electrical problem is detected in one or both coils, leading to shutdown mode. If this
occurs while the motor is moving, the <
StepLoss
> flag is raised to allow warning of the I
C master at the next
GetStatus1
command
that steps may have been lost. Once the motor is stopped,
ActPos
register is copied into
TagPos
register to ensure keeping the stop
position. The I
C master for some safety reasons can also issue a HardStop command.
HardStop

ResetPosition
This command is provided to the circuit by the I
2
C master to reset
ActPos
and
TagPos
registers to zero. This can be helpful to prepare
for instance a relative positioning.
