Van... de aktiv intelligencia kell hozza.
A rezonanciara hajlamos kozepsavban
tologatjak a lepes impulzus fazisat....

A BAUTZ szerint pl.
In every stepper drive, resonances appear in the medium frequency range that

result in a loss of torque, because the back-e.m.f. of the motor modulates 
the

current in the motor windings at certain speeds. Resonances in the medium

speed range can be seen as a region of potential instability that occurs as 
a

result of the electronic, magnetic and mechanical parameters of every 
stepper

motor system. The patented circuit that is used to suppress this effect 
works by

delaying or advancing the switching of the output current in a manner that

depends on the incoming step pulse rate. As a user, you should take this 
into

account if you want to apply a step-by-step pulse control method.



This special circuit avoids loss of torque in the medium frequency range. If 
it is

switched on, the motor maintains its torque during operation in the medium

speed range.
