If this ratio is not set before issuing the start moving command, it

will cause problems when running in “Absolute Mode” because the

HSL-4XMO won’t recognize the actual absolute position during

motion.

S-curve Profile Motion

This mode is used to move a single-axis motor to a specified posi-

tion (or distance) with a S-curve velocity profile. S-curve accelera-

tion profiles are useful for both stepper and servomotors. The

smooth transitions between the start of the acceleration ramp and

transition to constant velocity produce less wear and tear than a

trapezoidal profile motion. The smoother performance increases

the life of the motor and the mechanics of the system.
