Figure 20. Typical Single Step Response.
ELECTRONICDAMPING
Any steppermotor system when driven atvery low
stepping rates, has an oscillatory stepresponse as
shown in fig. 20.
This oscillatory behaviour is due to fact that the
motor reaches the stall position after each excita-
tion change through an acceleration and a succes-
sive deceleration. This causes the motor shaft to
rotate with jumps instead of uniform motion.
Another consequence of this oscillatory single step
response is that the long system settling time can
cause mechanical stresses to the driven load.
A second tedious effect is the enhancement of the
rotor oscillation when the driving step rate ap-
proaches the natural resonance frequency of the
motor. If the step rate is lower than this frequency,
the motor is behind the equilibrium position and the
velocity is near to zero when the next excitation
change occurs.
When the step rate isincreased to a value close to
the natural resonance frequency, anincrease ofthe
oscillations also occurs,and assoon as the oscilla-
tion amplitude exceeds the step amplitude, the
corrispondence between the rotor position and the
excitation sequence is lost and any subsequent
rotor movement is erratic as shown in fig. 21.
Asimple method to reduce the oscillationsproblem
is to use the halfstep driving,but this also limits the
maximum speedof the system.
When this limitation is not acceptable, other two
basic techniques may be adopted to damp the
system oscillations:
1.
A mechanical damper
2.
An electronic damping circuit.
