 Brief Description of ZD-2HE2270MH

ZD-2HE2270MH is a new-generation digital 2-phase stepper motor driver based on DSP control. The driver combines advanced DSP control technique and unique control circuit. The driver voltage is AC110-230V and driver current is below 7.0A. The driver can be used for types of 2-phase stepper motor with external diameter 86-130mm. The driver adopts circuit similar to servo control, so the motor can run smoothly with little vibration and noise. And the maximum positioning accuracy could reach 40,000 steps/rev. The product is widely used in big and medium-sized CNC equipment with higher resolution, such as engraving machine, medium-sized CNC machine tool, computer-controlled embroidery machine, packing machine, etc.

 

Specifications

1. High performance, low price
2.The driver features 16-grade micro-stepping with equal angular degree and constant torque; the highest resolution may reach 40,000 steps/rev.
3. The highest response frequency can reach 500Kpps
4.When the step-by-step impulse has halted for over 100ms, the coil current will automatically
reduce to half of the set value, to effectively reduce motor warming.
5.Photoelectric isolation signal input/output
6.Driver current from 1.0A / phase to 7.0A / phase, adjustable with 16 grades
7.Single power input, voltage range: AC 110V to 230V
8.Phase memory function (when the input has stopped unexpectedly or powered off, the driver will automatically memorize motor phase at that time.)
9. I/O signal, the driver uses photoelectric isolation technique and signal level is 5V ~ 24V, compatible
10.Function of pulse smooth technique makes the motor run stably at low speed. The level of smooth can be adjusted.
11.It features motor inductance adjustment function, giving full play to the adaptive motor.

Possible problems & Solutions

Caution

1, The input voltage is lower than AC270V.
2. Falling edge is effective of input pulse signal. If you need the rising edge to be effective, please set
inner parameter of the driver.
3. When the driver temperature goes beyond 75 degrees, it will halt working, and the fault indicator
ALM will be on. Until the temperature drops to 50 degrees, the driver may resume work after a
second-time power-on. In case of such overheat protection, please install heat sink.
4. In case of overcurrent (short circuit of load), the fault indicator ALM will be on. Please check motor
wiring and other fault of short circuit; after the fault is removed, it will resume upon a second-time
power-on.
5. In case of no motor, the fault indicator ALM will be on. Please check motor wiring; after the fault is
removed, it will resume upon a second-time power-on.
