<strong>VID29</strong>-XX and <strong>VID29</strong>-XXP series is a precise stepping motor of patent design, with gear<br />
reduction ratio 180/1, mainly used in dashboard instrumentation or other digital indicator<br />
equipments, to transfer digital signals directly and accurately to analog display output.<br />
Driven by 2 sequent logic pulse signals in 5V-10V, the output shaft can reach stepping angle<br />
resolution 1/12°. The angular speed can reach more than 500Hz.<br />
The new and modern design makes high efficiency, high position accuracy and extremely robust<br />
gear system. The special gear shape is helpful to decrease friction and noise. It chooses special<br />
material for each component to increase liability and safety for the motor.<br />
FEATURES<br />
- Wide working voltage: 5~10V.<br />
- Low current consumption: less than20mA, 5V, 2X100mW.<br />
- Wide working temperature: -40~105℃.<br />
- Extremely robust construction: Ф30mm X 7.6mm.<br />
- High μ-step resolution: 1/12°.<br />
- Directly driven by a μ-controller.<br />

The <strong>VID29</strong> can be easily installed. The four contact pins can be soldered on PCB circuits. If the<br />
application is subject in very strong vibrations, screws might be necessary.<br />

DRIVING PULSE AND CONTROL CIRCUIT<br />
Partial-Step Driving Mode<br />
In partial-step driving mode, the motor can be directly driven by a standard logic voltage level with<br />
less than 20mA current consumption. The bit-time sequence determines the turning direction of<br />
the motor. The time sequence diagram is as following:<br />

In μ-step driving mode, the motor can be driven by a current-level sequence. A μ-step is a 0.083º<br />
of pointer. The driving pulses consist of many different current level pulse sequences. The μ-step<br />
provides the pointer shaft continuous, smooth movement.<br />

<strong>VID29</strong>_xx<br />
In most of the <strong>VID29</strong>-XX applications, the angular range of the instrument dial is less than 300°.<br />
This allows to using mechanical stop to define the zero position. Generally the pointer will be<br />
reset to the zero position at each time power-up process.<br />
In power-up process, to quickly drive the pointer onto his initial stop position without creating<br />
visible and audible jitter of the pointer, we suggest a frequency acceleration process to speed<br />
up <strong>VID29</strong> step motor till a high speed. Below is an example:<br />
