- High hording torque under high speed
- High performance, low price
- Opto-isolated signal I/O
- Overvoltage, under voltage, overcorrect, phase short circuit
protection
- 15 channels subdivision and automatic idle-current reduction
- Motor torque is related with speed, but not related with
step/revolution
The connection between the driver and the two-phase hybrid stepping
motor is four-wire. The motor windings are connected in parallel
and in
series, and the connection method is good. The high-speed
performance is good, but the driver current is large (1.73 times
the motor winding
current). The drive current is equal to the motor winding current.

5.Driver FAQ:
1)What is a stepper motor and stepper driver?
Stepper motor is a special motor for precise control of speed and
position. It rotates at a fixed angle (called "step angle") step by
step, so called stepper motor. It is characterized by no cumulative
error. It receives every pulse sent from the controller and drives
the motor at a fixed angle by the driver. Therefore, it is widely
used in various open-loop control.
The stepper driver is a kind of power amplifier that can make the
stepper motor operation. It can convert the pulse signal from the
controller into the power signal of the stepper motor. The speed of
the motor is proportional to the pulse frequency, so that control
pulse frequency can be precisely adjusted speed, and control the
pulse can precise positioning.
2)What is the subdivision of the driver? What is the relationship
between the speed and the pulse frequency?
Stepper motor due to its own unique structure, the factory are
marked with "motor inherent step angle" (such as 0.9° / 1.8 °,
means half-step work every step of the turn angle is 0.9 °, the
whole step is 1.8 ° ). However, in many precise control and
occasions, the whole step angle is too large, which affects the
control accuracy and the vibration is too large. Therefore, it
requires many steps to complete an inherent motor step angle, which
is called subdivision drive and the electronics which can realize
this function are called subdivided drivers.
V:Motor speed(r/s) P:Pulse frequency(Hz)
θe:Motor inherent step angle m:Subdivision (whole step is 1, half
step is 2)
3) What are the advantages of subdivision driver?
● Increasing step uniformity by reducing the step angle,so that can
improve the control accuracy.
● Can greatly reduce the motor vibration, low-frequency oscillation
is the inherent characteristics of the stepper motor, using of
subdivision is the best way to eliminate it.
● can effectively reduce the torque ripple, increase the output
torque.
These advantages are generally recognized by the user, and bring
them benifits, so we recommend using subdivision driver.
4) Why does my motor only operate in one direction?
● The direction signal may be too weak, or the wiring polarity is
wrong, or the signal voltage is too high, burnout direction current
limiting resistor.
● Pulse mode mismatch, signal is pulse / direction, driver must be
set to this mode; drive must be in the same mode if the signal is
CW / CCW (double pulse mode), or the motor will run in only one
direction.
