Micro-step mode
In micro-step mode, the number of microsteps for controlling a stepper motor is specified. A stepper motor is usually controlled in full-step or half-step mode. With each pulse, the current in the motor windings of a stepper motor are switched on or off according to a certain pattern. This causes the motor to rotate abruptly by a small angle. A disturbing torque ripple then occurs during operation. You can prevent abrupt movements of the motor shaft by switching to micro-step mode. In this mode, the winding currents are not switched; instead they are output in the form of a continuous sine or cosine curve.
The default value is 8.
Value | Number of microsteps per step |
|---|---|
1 | Full step (2-phase) |
2 | Full step (1-phase) |
3 | Half step |
4 | 4 µ-steps per step |
5 | 8 µ-steps per step |
6 | 1 µ-steps per step |
7 | 32 µ-steps per step |
8 | 64 µ-steps per step |
