The "dead" state of the computerized embroidery machine is: the needle bar is stuck in place (the embroidery frame does not move) while the computerized embroidery machine is working, and the lever stops, the buttons fail, or the machine stops in a certain state and cannot perform any operations, etc. . The crashes are caused by the following reasons:
1. interference
Interference source from the neutral line: The interference of the system power supply mainly comes from the neutral line. If the user cannot provide a standard and reliable neutral line, the interference from the neutral line will occur immediately. In the design of the electronic control power supply, we have avoided the possible interference caused by the neutral line in the three-phase 380V power supply system, but in the case of using 220V power supply, because the neutral line must be used, such as the neutral line is unreasonable and the line If the diameter is not enough, it may cause interference to the system. Therefore, the customer must be required to provide a standard and reasonable neutral wire.
Other interference: The computerized embroidery machine is a complex system that combines electronic control and machinery with multiple execution components. In order to avoid mutual interference between components and ensure the stable and safe work of the system, we have adopted complete shielding measures to achieve effective For shielding, the customer must be required to provide a standard ground wire. If there is no ground connection, the system may crash.
2. Signal cables and connectors are loose
After the machine has been transported for a long distance or operated for a long time, it may cause the cable to loosen or the connector cannot be contacted*. In this way, it may cause a crash during system communication. Although this situation is extremely rare, it should be used during machine maintenance and repair. Pay attention to the inspection of the connector.
3. The number of stitches stored in the memory exceeds the allowable value
When there are too many patterns entered and the memory capacity is insufficient, the system may crash. At this time, please check the number of needles in the memory, save the temporarily unused patterns to the floppy disk, clear the unused patterns, and ensure the running space of the memory to eliminate the crash
