Reasons for the formation of magnetic field

Originally, the Z-axis motor power supply line and the encoder feedback line are long, and are entangled when the wiring is placed together, causing the motor power line and the encoder line to form a magnetic field to be decoupled, causing electromagnetic interference, resulting in the alarm, which complicates the problem. Turn. In order to solve this problem, we and the manufacturer have gone a lot of detours, and it took a lot of energy and time to solve. There are many factors affecting the numerical control equipment, but in terms of electromagnetic interference, it comes from two types of equipment inside and outside the equipment. As far as the machine is concerned, the main reason is that the power supply design is unreasonable, the numerical control system installation position and the connection wiring are unreasonable, and the electromagnetic grounding caused by the signal grounding and the power supply grounding arrangement is unreasonable. As far as the machine is concerned, the main reason is that the power supply is polluted (inferior rectifier equipment and engine test equipment, etc.), and the welding machine, electric spark, lightning, etc. will produce sharp pulses.

The high-frequency part of these pulses is emitted in the form of radio frequency, which forms electromagnetic interference to the numerical control system and the measurement system. When the edge can be restored to the normal state (above 20Mn), the heating cable will return to normal. Since the repaired heating cable still has a hidden danger of moisture infiltration at the joint, in order to avoid moisture infiltration, the insulation is lowered again, and the heating cable must still be energized to maintain a certain temperature. At the same time, in order to save energy and protect the equipment, the control temperature can be adjusted to about 100 °C (formerly 350 °C), and the original set value is restored before starting work. Advantages and effects of the repair method This repair method not only repairs the damaged heating cable, saves the cost of spare parts, but also greatly shortens the time for maintenance and repair.
