The Nema 42 Stepper Driver 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
High performance, low price
The driver features 16-grade micro-stepping with equal angular degree and constant torque; the highest resolution may reach 40,000 steps/rev.
The highest response frequency can reach 500Kpps
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.
Photoelectric isolation signal input/output
Driver current from 1.0A / phase to 7.0A / phase, adjustable with 16 grades
Single power input, voltage range: AC 110V to 230V
Phase memory function (when the input has stopped unexpectedly or powered off, the driver will automatically memorize motor phase at that time.)
I/O signal, the driver uses photoelectric isolation technique and signal level is 5V ~ 24V, compatible
Function of pulse smooth technique makes the motor run stably at low speed. The level of smooth can be adjusted.
It features motor inductance adjustment function, giving full play to the adaptive motor.
