Micro-Stepping
If the motor controller is used in
(p.12), the desired micro step mode must be preselected by the combination of
switch SW4 to SW6 and SW 8.
By preselecting the micro steps per motor revolution, the precision, the resulting vibrations, and the noise of the motor can be
directly influenced.
The higher the micro steps, the better the precision and at the same time vibrations and noise are reduced to a minimum.

Note
(p.12) is used, the selection of the executed micro steps per motor revolution in the master controller and
in the motor controller must be the identical.
If, for example, 200 micro steps per motor revolution are set in the motor controller, but 400 micro steps per motor revolution
are set in the master controller, and the master controller issues the movement command for one motor revolution, the motor
will execute 2 revolutions.
The reason for this is that instead of the 200 pulses expected by the motor controller for one motor revolution, 400 pulses
were now emitted by the master controller and these were converted into 2 motor revolutions.
4.1.4
Selection Constant Speed
If the motor controller is used
(p.13), the desired speed must be preselected by the combination of switches SW4 to
SW6 and SW8.
Acceleration and deceleration are set to a fixed time value of 250 ms.
The Micro Stepping is set to 25600 (1/128 Step).
