| Textile -- Common problems of electric control system of winder | |
| Fault phenomenon | Causes and solutions |
| The starting motor does not rotate | ① Check whether the driver motor power line, motor hall line and hall sensor are correctly plugged. ② When the brake is lowered, the hall sensor lamp does not light up: 1. Check whether the distance between the hall sensor and the magnet is too far, and whether the magnet is displaced, which causes no sensing. 2. Replace hall sensor. 3. Replace the drive. ③ Whether the encoder can be started after removal: 1. If it can be started, reset the up and down travel of the tension rod. 2. Unable to start, eliminate the cause of encoder. ④ Replace the motor or driver. ⑤ The whole machine starts slowly: 1. Confirm whether the speed of the acquisition host is used, whether the speed parameters of the acquisition host are set correctly, and whether the wire drawing machine runs at a low speed. 2. The starting speed is set very low. ⑥ The whole machine cannot be started: the machine is locked and needs to be unlocked by the manufacturer. |
| Tension up and down travel cannot be set | ① Check whether the encoder is properly inserted. ② Check whether the distance between magnet and encoder is less than 4mm (non-contact encoder). ③ Replace encoder or driver. |
| OL fault (motor overload) | ① Check whether the motor wiring is correct ② Check motor 3 for interphase short circuit or 3 for short circuit to motor housing ③ Check whether the motor shell is reliably connected to the frame ④ Replace the motor or driver |
| OC fault (motor overcurrent) | ① Check whether the motor wiring is correct ② Check whether the motor is locked ③ Replace the motor or driver |
| No communication with the drive | ① No communication in individual spindle position: 1. Check whether the communication line is plugged in properly, 2. Check whether the communication line sequence is correct, and 3. Replace the driver or communication line. ② All drivers controlled by one communication port of the whole machine or communication board have no communication: 1. Whether the communication board is connected to 24V power supply; 2. Whether the communication board and the driver are connected reliably, 3. Whether the AB wiring sequence is correct, 4. Replace the communication line, 5. Replace the communication board |
| No communication on touch screen | ① Whether the communication board is connected to 24V power supply ② Check whether the communication line between the touch screen and the communication board is connected reliably and whether the communication line model is correct ③ Replace the communication cable or communication board |
