Engraving machine inverter which interfere with the way and generally how to deal with
Engraving machine inverter which interfere with the way and generally how to deal with?
A. The mode of transmission:
(1) radiation interference;
(2) conducted interferenceLaser cutting machines for sale
B. The anti-jamming measures: the interference signal transmitted through radiation, mainly
through the wiring and the radioactive sources and line interference shielding to weaken.
Interference signal transmitted through the line, mainly through the installation of the
inverter input and output side of the filter, reactor, or toroid, etc. to deal with. The
specific methods and precautions are as follows:
(1) the signal lines and power lines to be perpendicular to cross or sub-slot wiring.
(2) Do not use metal wires connected to each other.
(3) shielding tube (layer) should be reliable grounding, and to ensure that the entire
length of the continuous, reliable ground.
(4) twisted pair shielded cable to the signal circuit.
(5) shielding layer take place as far away as possible from the inverter and the inverter
ground separate.
(6) ring can be used in the inverter input power line and output line: input line
together in the same direction around the four laps, while the output line in the same
direction around the circle can be. Winding is required, try to ring close to the drive.
(7) general interference with equipment and instruments, may take the shield and other
anti-jamming measures
