Digital stepper motor
JKD7208S
1. Products' introduction
1. General introduce
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.
2.Characteristic
1.New 32-bit DSP technology 2.Can drive two phase stepping mootors of 4,6,8 lines
3.Ultra-low vibration noise 4.Optical isolation differential signal input
5.Built-in high subdivision 6.The pulse reponsse frequency can reach to 500KHZ(Factory default 200KHZ)
7.Automatic parameter adjustment function when power on
8.The current setting is convenient and can choose between 0.1 to 7.2A
9.Variable current control reduces the heating of the motor
10.Subdivision setting range is between 200 to 51200
11.The current automatically halve at rest
12.Has the protection function of overpressure underpressure and overcurrent
3. 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.
