Move (DIR, N_STEP)
Table 42.
The move command produces a motion of N_STEP microsteps; the direction is selected by
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 can be only performed when the motor is stopped. If a motion is in progress
the motor must be stopped and then it is 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 paragraph
GoTo (ABS_POS)
Table 43.
The GoTo command produces a motion to 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.).
This command can be given when the outputs are in high impedance or the motor is
stopped or running with constant speed.
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
