Vexta DFU1514W Oriental Motor 5-Phase Microstepping Driver

The Oriental Motor Vexta DFU1514W 5-Phase Microstepping Driver is the model driver in the NanoStep UFK-W Series Package. The DFU1514W Driver is compatible with Standard, TH Geared, and PN Geared Types.

Nanostep is a series of stepping motors and drivers that combines high-performance 5-phase microstepping drivers with high-torque/low-vibration 5-phase stepping motors. They provide smooth and precise operation.

The primary feature of stepping motors is the ability to obtain precise positioning. They achieve this by rotating and stopping at step angle increments that are determined by the pole structure of the rotor and stator. Rotating in step angle increments, however, also produces changes in rotor speed and resonance at certain speeds that can increase vibration.

Microstep driving provides a finer degree of control of the basic motor step angle by regulating the current sent to the motor coils, resulting in, low vibration, even at low speed.

• Since the basic motor step angle (0.72°/full step) can be divided into proportions ranging from 1/1 to 1/250, smooth operation in fine increments is possible.

• Technology that changes the motor drive current smoothly suppresses motor vibration and makes operation audibly quieter.

UFK-W enables step angles to be set independently on two resolution selection switches (16 possible microstep resolutions with as many as 250 microsteps per full step). This enables two independent resolutions to be selected by using the resolution select input. Changing resolution should occur when the motor is in the stop position. This will eliminate the chance of positioning error.
