14.4 Optimisation of the Current Shape - BLOW UP
For an ideal stepper motor, the holding torque is a true sine wave. In practice, the torque
curve more or less differs from this ideal shape.
Therefore, the MSD2
+
offers the possibility to select a current shaping as shown below. In
function of the motor used, it is possible to increase the motor performance during run and
acceleration.

The optimum current shape must be determined by a test of the complete system:
control unit, motor, load.
