Provisions on wiring of electrical equipment in electronic belt scale standards

The power cord of the heavy sensor and angular displacement sensor should be shielded transmission lines of more than 1.0 mm2.Electronic belt scaleOrdinary copper wires cannot be used for electrical equipment wiring. Shielded transmission lines should be laid with company-made metal protective pipes or metal trunking as much as possible. The signal shielding layer of weight sensors and angular displacement sensors should be grounded at one end. , such as connecting the instrument panel chassis or the sensor power ground. If several instrument panels are installed together, the same rated voltage and the same type of wiring can be put together.

Power lines with different rated voltages, and electronic belt scale switching I\/O lines should be laid separately and avoided as much as possible. If electrical equipment such as instrument panels and servo drives are installed in the same control box, it is recommended that the instrument panel power supply is in front of it. 1-stage filter. The closer the filter is to the instrument panel, the better. When several instrument panels are installed together, the instrument panel power supply can be connected in parallel and then connected to the output of the filter. Add 1-stage high-frequency filtering before and after the servo drive. The filter can reduce the interference to other facilities. The filter can be made by using a large magnetic ring. Four power cords can be rotated in the same direction on the magnetic ring for 3-5 turns. In addition, the servo drive I\/O power cords should be twisted together. And use 4-wire wiring. Do not connect the three output power lines of the servo drive to the terminal blocks in different ways.
