Overview
The DM860H is a new generation digital 2-phase stepper motor
driver, based on a 32-bit DSP processor, combination of the
anti-resonance, low noise, micro-step and low temperature rise
technology significantly improve the performance of the stepper
motor, has low noise, small vibration, low temperature rise and
high-speed torque. The driver use online adaptive PID technology,
without manual adjustment can be automatically generated optimal
parameters for different motors, and achieve the best performance. Supply voltage range from 18VAC to 80VAC or from 24VDC to 110VDC,
suitable for driving various 2-phase hybrid stepping motors which
phase current below 7.2A. The microstep can be set from full step
to 51200steps/rev and the output current can be set form 2.4A to
7.2A; with automatic idle-current reduction, self-test,
overvoltage, under-voltage and over-current protection.
Common indicator of 2 phase stepper motor driver
What are stepper motors and stepper drives?
Stepper motor is a special motor specially used for precise control
of speed and position. It runs step by step at a fixed angle
(called "step angle"), so it is called stepper motor. Its
characteristic is that there is no accumulated error. It receives
every pulse signal from the controller, and the motor runs at a
fixed angle under the drive of the driver, so it is widely used in
various open loop control.
The stepper driver is a power amplifier that can make the stepper
motor run. It can convert the pulse signal sent by the controller
into the power signal of the stepper motor. The speed of the motor
is proportional to the pulse frequency, so the control pulse
frequency can be adjusted accurately. Accurate positioning can be
achieved by controlling the number of pulses.
What is driver segmentation? What is the relation between the speed
of stepping motor and pulse frequency?
Due to the unique structure of the stepping motor, it is marked
with "inherent step Angle of the motor" when leaving the factory
(for example, 0.9°/1.8°, indicating that the rotation Angle of each
step of the half-step is 0.9° and that of the whole step is 1.8°).
However, in many precision control and occasions, the whole step
Angle is too large, affecting the control accuracy, and vibration
is too large, so many steps are required to complete a motor
natural step Angle, which is the so-called subdivision drive, the
electronic device that can achieve this function is called the
subdivision driver.
Applications of stepper motor driver
It can be applied in a variety of small scale automation equipment
and instruments, such as labeling machine, cutting machine, packing
machine, drawing machine, engraving machine, CNC machine and so on.
It always performs well when it is used in equipment which requires
for low-vibration, low-noise, high-precision and high-velocity.
