Move (DIR, N_STEP)
Table 40.
The move command produces a motion of N_STEP microsteps; the direction is selected by
the DIR bit ('1' forward or '0' reverse).
The N_STEP value is always in agreement with the selected step mode; the parameter
value unit is equal to the selected step mode (full, half, quarter, etc.).
This command keeps the BUSY flag low until the target number of steps is performed. This
command can only be performed when the motor is stopped. If a motion is in progress the
motor must be stopped and it is then possible to perform a Move command.
Any attempt to perform a Move command when the motor is running causes the command
to be ignored and the NOTPERF_CMD flag to rise (see
GoTo (ABS_POS)
Table 41.
The GoTo command produces a motion to the ABS_POS absolute position through the
shortest path. The ABS_POS value is always in agreement with the selected step mode; the
parameter value unit is equal to the selected step mode (full, half, quarter, etc.).
The GoTo command keeps the BUSY flag low until the target position is reached.
This command can only be given when the previous motion command has been completed
(BUSY flag released).
Any attempt to perform a GoTo command when a previous command is under execution
(BUSY low) causes the command to be ignored and the NOTPERF_CMD flag to rise (see
