Stepper Drivers with Oscillators
An oscillator is a device that is used to produce pulses for driving a step motor at a preset speed. In microstep drivers, the oscillator is usually incorporated into the hardware construction of the stepper drive. In oscillator mode, the pulse input becomes a run/stop signal: when this signal is set low, the motor accelerates to a preset speed and slews. Raising the input high (to 5 volts) causes the step driver to decelerate to rest. The digital oscillator derives its timing from a quartz crystal for low drift and repeatable ramps. The speed of the oscillator can be set by an on-board potentiometer, or an external pot, or an external 0-5 volt analog signal.
