1. Introduction, Features and Applications
Introduction
Micro stepping driver is particularly suitable for the applications desired with extremely low noise
and low temperature rise technology which significantly improve the performance of the stepper
motor that leads to low temperature rise, low vibration. With the adjustment technology (step/rev and
current) according to different motors, the driven motors automatically generate optimal parameters
for different motors, and achieve the best performance at higher speed. It is suitable for driving 2-
phase and 4-phase hybrid stepping motors.
Features
High performance, cost-effective
Suitable for 2-phase and 4-phase motors
Support PUL/DIR and CW/CCW modes
Short-voltage, over-voltage, over-current and short-cicuit protection
Low temperature rise, smooth motion
Pulses Response Frequency Can Reach 200KHz
Applications
Suitable for a wide range of stepping motors, from NEMA size 17 to 34. It can be used in various
kinds of machines, such as X-Y tables. And a variety of large-scale automation equipments and
instruments. For example: labeling machine, cutting machine, packaging machine, plotter, engraving
machine, CNC machine tools and so on. It always performs well when applied for equipment which
requires for low-vibration, low-noise, high-precision and high-velocity.

It is recommended to use automatic idle-current mode, namely current automatically reduce
to 60% when motor stops, so as to reduce driver heating and motor heating;
It is recommended to mount the driver vertically to maximize heat sink area. Use forced
cooling method to cool the system if necessary.
3. Pin Assignment and Description

Wiring Notes
To prevent noise incurred in PUL/DIR signal, pulse/direction signal wires and motor wires
should not be tied up together. It is better to separate them by at least 10 cm, otherwise the
disturbing signals generated by motor will easily disturb pulse direction signals, causing
motor position error, system instability and other failures.
If a power supply serves several drivers, separately connecting the drivers is recommended
instead of daisy-chaining.
It is prohibited to pull and plug connector P2 while the driver is powered ON, because there is
high current flowing through motor coils (even when motor is at standstill). Pulling or
plugging connector P2 with power on will cause extremely high back-EMF voltage surge,
which may damage the driver.

7. Power Supply Selection
The Microstep Driver can match Large and small size stepping motors (from Nema size 17 to Nema
size 34
). To achieve good driving performances, it is important to sele
current properly. Supply voltage determines the high speed performance of the motor, while output
current determines the output torque of the driven motor (particularly at lower speed). Higher supply
voltage will allow higher m
otor speed to be achieved, at the price of more noise and heating. If the
motion speed requirement is low, it
improve reliability.
Regulated or Unregulated Power Supply
Both regulated an
d unregulated power supplies can be used to supply the driver. However,
unregulated power supplies are preferred due to their ability to withstand current surge. If regulated
power supplies (such as most switching supplies.) are indeed used, it is importan
current output rating to avoid problems like current clamp. On the other hand, if unregulated supply is
used, one may use a power supply of lower current rating than that of motor (typically 50%
motor current). The reason is that the driver draws current from the power supply capacitor of the
unregulated supply only during the ON duration, but not during the OFF duration. Therefore, the
average current withdrawn from power supply is consid
