GetOTPParam
This command is provided to the circuit by the I
OTP Memory
GotoSecurePosition
This command is provided by the I
priority encoder
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
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
ResetPosition
This command is provided to the circuit by the I
for instance a relative positioning.
