Chapter 4 Attention

4.1 Wiring precautions

4.1.1 Guide for routing of towline cable

1. When releasing the cable from the coil, it is necessary to prevent the cable from twisting (it needs to be laid along the tangent direction) and to straighten the cable.
This work should be carried out before laying the cable, providing a period of stress release for the cable. Because the manufacturing process cannot fully guarantee that the cable is straight and without any distortion, the printed markings on the cable surface rotate along a tiny spiral.

2. The cable is not allowed to twist when it is installed in enclosed space.

The twist during installation may lead to premature damage of the core strand.This effect is gradually strengthened in the operation of the cable, resulting in the phenomenon of back-twisting, which eventually leads to core breakage and failure.

3. Cables must be laid side by side in the towing brackets. Isolating pieces should be used to separate cables as far as possible. The gap between cable and isolator, separator or its adjacent cables should be at least 10% in diameter.

4. The cables should be installed symmetrically according to the weight and size of the cables. The larger diameter cables should be placed outside. Smaller and lighter cables should be placed inside. Cables can also be placed from inside to outside in order of decreasing size. One cable should be laid on the other cable without the use of isolation panels.

5. For vertical suspension tow chains, more free space must be left in the vertical bracket because the cable will be lengthened during operation. After a short period of operation, it is necessary to check whether the cables are running along the central area and adjust them if necessary.

6. For self-supported drag chain structure, cables are fastened to moving points and fixed points. It is necessary to use the appropriate cable support provided by the towing chain supplier. When operating at high acceleration, the applicability of cable strapping is very limited. It should be prevented to tie multiple cables together. Cables should not be fixed or tied to the movable parts of the tow chain in any way. The gap between fixed point and bending motion should be wide enough.

7. For sliding towing chains, we suggest that cables should only be fixed on moving points. A small cable protection area needs to be set at the fixed point.(refer to the assembly instructions of the drag chain supplier).

8. Make sure that the cable moves along the center area under the required bending radius. Do not apply tension to the cable (do not pull too tight), otherwise the friction inside the tow chain will lead to cable sheath wear;Do not let the cable loose too much in the tow chain, otherwise it will easily lead to wear and tear between the cable and the inner wall of the tow chain, or entanglement with other cables.

9. If the cable is not running smoothly, you can check whether there is any distortion along the longitudinal axis during operation. The cable should rotate slowly at a fixed point until it runs smoothly.

10. In view of the absolute size of cables and towing chains, their length variation characteristics are quite different. In the first few hours of operation, the cable stretched naturally. For towing chains, it takes many hours to run this phenomenon. Such a big difference can be solved by regularly checking the installation location of cables. We recommend regular inspections, once every three months in the first year of operation, and then at each maintenance time.
The contents include checking whether the cable is completely free to move within its proper bending radius and adjusting it if necessary.

4.1.2 Specification for machine tool wiring

1. Wiring specification for power supply

(1) Strong electricity

  • Strong and weak electricity is strictly separated.

The power line is selected according to the size of the power line diameter. The attached is the cable diameter and power comparison table.

  • Strong current plus short-circuit protector, filter and other auxiliary devices.

(2) Weak current (take DC24V as an example)

  • The power positive and negative pole wiring colors are distinguished, for example:
    The red line is connected to the positive pole, and the blue line is connected to the negative pole.
  • Larger interference loads, such as servo and solenoid valves, are supplied separately from the controller.

2. Specification for earth wire connection

  • The ground wire adopts standard yellow green double color line.
  • There are some high frequency signals (PWM, pulse, encoder, capacitance signal, etc.) in the laser cutting machine tool. It is suggested to use multi-point grounding.
  • Galvanized earthing screws for machine tools and earthing with special earthing wires. The resistance between the grounded metal main body and the main grounding point should not exceed 0.1 ohms.

3. Specification for signal (control) wiring

  • Signal line color: Such as black.
  • The signal line is selected according to the power size.
  • DC 24V solenoid valve is recommended. Absorption circuit is added at both ends of solenoid valve, that is, a continuous current diode (attention direction, current resistance value, voltage resistance value) is connected in parallel at both ends of solenoid valve, as shown in the following figure:
  • It is recommended that the digital signal (PWM) shield layer be grounded at two ends and the analog signal (DA) shield layer be grounded at one end.
    Single ended grounding can avoid low frequency current noise on shielding layer. Double-terminal grounding can effectively eliminate high-frequency interference. If the transmission cable is long, multi-point grounding is recommended to ensure that the shielding layer is equipotential.
  • The resistance of the cutting head connected by the amplifier to the shell of themachine tool is not more than 1, and the resistance of the grounding point to the electric cabinet is not more than 6.

4. Other specifications

  • Each wire is marked and marked clearly and accurately.
  • Line and line are arranged in parallel. No crossover is allowed. The arrangement of wiring harness and line pipe should be straight.
  • When choosing Friendess wires, choose the appropriate type of wire according to the layout space, do not accumulate hovering.
  • All wiring must be reliable and not loosen to prevent ignition.
  • Wiring avoids formation of loops and prevents antenna effects. A current loop consisting of a signal source, a transmission line, a load is equivalent to a magnetic field antenna. As shown in the figure below, the wrong way is on the left side and the right connection is on the right.
  • The recommended connection is star-structure connection, and serial connections are not recommended.

Chapter 5 FAQ

5.1 Host unable to enter system

  1. Check whether the power port of the host and display is loose, and whether the 24V voltage is normal?
  2. If the host can turn on, check whether the display power is loose or not. Is the voltage normal?
  3. If the display is normal, the system cannot be entered, and the system may get virus. Following the following procedures:
    • Use win+R to manually boot explorer.exe loading;
    • Restart host to see if it is normal to enter the host interface.
    • If you enter the host interface, please use antivirus software to remove the virus. If you are still unable to enter, please restore the system.

5.2 Touch screen does not display

  1. Check whether the display power supply port is loose, and the 24V voltage is normal?
  2. Check if the BClink interface is inserted.
