Woodworking engraving machine stepper motor drive solutions interference
Woodworking engraving machine stepper motor drive solutions interference
As the general woodworking engraving machine stepper motor and drive enclosure did not use aluminum, titanium, magnesium alloy casing magnetically shielded, so the sensitivity of the receiver system cause interference, it can not work, and pollution power, resulting in single-chip control systems and PC can not communicate, causing serious microcontroller crash, caused difficulties for normal use, so the interference problem must be addressed. 
May take the following measures to solve them: 
A. Installation of power filters, reducing AC power pollution. 
B. "A little ground" principle. The mains filter, the drive PE (ground) (driver and chassis floor insulation), control and direction of the pulse PULSE- DIR- short pulse lead after the motor ground wire, cable between the drive and motor protective cover, drive shielded lines are connected to the grounding screw on the chassis wall and ask good contact. 
C. Try to increase the control line and power line (L, N), from the motor drive cable (U, V, W) between avoid cross. Instance we are dealing with two dual-axis drive system drives in the same chassis installation position, a drive plate forward and the other backward, and so on the structural arrangement of these leads as short as possible. 
D. Use shielded cables to reduce outside interference on their own, or their own (power line) interference of the outside world. 
After the above processing, the system is reliable.
