Writes VALUE in PARAM register
Returns the stored value in PARAM register
Put the device in step clock mode and impose DIR
direction
Makes N_STEP (micro)steps in DIR direction
(Not performable when motor is running)
Brings motor in ABS_POS position (minimum path)
Perform a motion in DIR direction with speed SPD until
SW is closed, the ACT action is executed then a SoftStop
takes place
Performs a motion in DIR direction at minimum speed
until the SW is released (open), the ACT action is
executed then a HardStop takes place
Brings the motor in HOME position
Brings the motor in MARK position
Resets the ABS_POS register (set HOME position)
Device is reset to power-up conditions.
Stops motor with a deceleration phase
Stops motor immediately
Puts the bridges in High Impedance status after a
deceleration phase
Puts the bridges in High Impedance status immediately
Returns the status register value
