Motion commands
Motion commands will produce a motion in order to perform a user-defined number of
microsteps in a user-defined direction that are sent to the device together with the command
(see Figure 8).
Performed motor motion is compliant to programmed speed profile boundaries
(acceleration, deceleration, minimum and maximum speed).
Note that with some speed profiles or motion commands, the deceleration phase starts
before the maximum speed is reached.
Figure 8.
Motion commands examples
6.7.4
Stop commands
A stop command forces the motor to stop. Stop commands can be sent anytime.
SoftStop command causes the motor to decelerate, ignoring MIN_SPEED constraint, with
programmed deceleration value and then to stop.
HardStop command stops the motor instantly ignoring deceleration constraint.
SoftHiZ command causes the motor to decelerate, ignoring MIN_SPEED constraint, with
programmed deceleration value and then forces the bridges in high impedance state (no
holding torque is present).
HardHiZ command instantly forces the bridges in high impedance state (no holding torque is
present).
6.7.5
Step-clock mode
In step clock mode the motor motion is defined by the step clock signal applied to STCK pin.
At each step clock rising edge, the motor is moved of one microstep in the programmed
direction and absolute position is consequently updated.
When the system is in step clock mode the SCK_MOD flag in STATUS register is raised,
SPEED register is set to zero and motor status is considered stopped whatever the STCK
signal frequency (MOT_STAUS parameter in STATUS register equal to “00”).
