In the many optical laser marking machine out of the wave before the situation encountered more, but the most common is caused by signal interference, interference signal amplitude of the main factors are laser power and acousto-optic drive, and the external power grid fluctuations The role of the galvanometer interference source check. In the laser power supply is not open when the light used to scan the line out of the lines show whether the line was wavy. In the computer equipment is a straight line, but the fight is out of the wavy line, which is the most obvious signal interference characteristics!
Fiber laser marking machine to solve the problem of interference, you can start from the following aspects:
Use shielded wire to reduce interference with the outside world, or their own (power cord) on the outside world interference. Install the power filter to reduce the interference of the AC power supply to the equipment. (L, N), the distance between the motor drive line to avoid cross.For example, we deal with dual-axis drive system in two unified drive installation location of the chassis, a drive nameplate toward the , And the other towards the rear, and in the structural arrangement of these leads as short as possible. "One point grounding" principle. Connect the ground of the power supply filter, the ground of the driver PE (ground) (the driver is insulated from the chassis base plate), the control pulse PULSE- and the direction pulse DIR- shorted lead wire, motor ground wire, cable guard between the driver and motor, Shielded lines are connected to the grounding column on the chassis wall, and requires good contact.
