Run frequency / velocity f
RUN
The run frequency can be set differently for each drive (DS128).
If the selected running frequency is lower than the set start-stop frequency f
ss
the set fre-
quency is approached without ramp (rectangular traverse profile).
i
Make sure that the step resolution also has an influence on the speed of the mo-
tor, but is not transmitted with a run command.
Start-Stop Frequency f
ss
The f
ss
start-stop frequency is the frequency to which the motor can be accelerated under
load from a standstill without losing the synchronisation of the electrical field and without
losing steps.
The maximum f
ss
start-stop frequency mainly depends on the moment of inertia of the
load, as well as from the friction of the system.
Maximum Frequency / Velocity of the Axis f
permissible
When choosing a stepper motor, remember the following:
The maximum frequency/velocity is determined by the application. At this frequency, the
motor must reach a torque high enough to move its load.
