16.3.10. SetStallParam
This command sets the motion detection parameters and the related stepper motor parameters, such as the minimum and maximum
velocity, the run- and hold current, acceleration and step-mode. See
16.3.11. SetMotorParam
This command is provided to the circuit by the I
Refer to Table 18 to see the meaning of the parameters sent by the I
Important: If a SetMotorParam occurs while a motion is ongoing, it will modify at once the motion parameters (see
Controller). Therefore the application should not change parameters other than Vmax and Vmin while a motion is running, otherwise
correct positioning cannot be guaranteed.
SetStallParam corresponds to the following I
