Then, when I need to hold a load, I can stop the motor (signal of "0 Hz") and have it hold. List & Sarosero, Steppers can be used with encoders, and there are some chips available to do this without implementing it yourself. During outdoor use, the stepper motor, driver and controller must be protected from the elements by an appropriate cover while still able to provide adequate air flow and cooling. This is useful because every stepper motor has a speed that causes itself to vibrate at the resonant frequency of its own moving parts. I understand that I'm supposed to input pulses into the step and dir but how does it really work? Do I input digital pulses to the "step" to ramp motor up/down? What about dir? Stepper motors are the motor of choice for many precision motion control applications.
