The GoMark command keeps the BUSY flag low until the MARK position is reached. This
command can be given only when the previous motion command has been completed
(BUSY flag released).
Any attempt to perform a GoMark command when a previous command is under execution
(BUSY low) causes the command to be ignored and the NOTPERF_CMD flag to rise (see
Section
ResetPos
Table 45.
The ResetPos command resets the ABS_POS register to zero. The zero position is also
defined as HOME position (see
ResetDevice
Table 46.
The ResetDevice command resets the device to power-up conditions (see
At power-up the power bridges are disabled.
SoftStop
Table 47.
The SoftStop command causes an immediate deceleration to zero speed and a consequent
motor stop; the deceleration value used is the one stored in the DEC register (see
Section
When the motor is in high-impedance state, a SoftStop command forces the bridges to exit
from high-impedance state; no motion is performed.
This command can be given anytime and is immediately executed. This command keeps
the BUSY flag low until the motor is stopped.
