Description:
JKD7208S is a new digital stepper motor driver by JKONGMOTOR. It adopts the latest 32-bit DSP digital processing technology. The drive control algorithm adopts advanced variable current technology and advanced frequency conversion technology. The driver has small heating, small motor vibration and stable operation. Users can set any subdivision within 200 ~ 51200 and any current value in the rated current to meet the application needs in most occasions. Thanks to the built-in micro-subdivision technology, the subdivision effect can be achieved even under the condition of low subdivision. The operation is smooth and the noise is ultra-small under low, medium and high speed. The driver integrates the parameter auto-adjust function, which can automatically generate optimal operating parameters for different motors to maximize the performance of the motor.
Application
Suitable for all kinds of small and medium sized automation equipment and instruments, such as: engraving machine, marking machine, cutting machine, laser lighting, plotter, cnc machine, automatic assembly equipment, etc. It use very well in the equipment that user expects small noise, and high peed.

1, Q: The motor does not turn and no holding torque:
A: ① check whether the power line is connected to the wrong voltage is too low, need to increase the voltage or correct the power line
② check whether the motor wiring is correct, if not correct motor wiring. Check if the motor wiring is correct, if not, correct the motor wiring.
