| Textile -- Common problems of winding machine | |
| Fault phenomenon | Causes and solutions |
| CnErr (communication failure) | ① Two spindles controlled by a single driver report communication failure: 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 There is no communication on one side of the machine or the whole machine: 1. Whether the communication board is connected to the 24V power supply, 2. Whether the wiring between the communication board and the driver is reliable, 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 model of the communication line is correct. ③ Replace the communication cable or communication board. |
| OL fault (motor overload) | ① Check whether the power line and hall line of the motor are connected reliably and correctly, and whether the motor is locked. ② Check the interphase short circuit of motor 3 or the short circuit of motor 3 to the motor housing. ③ Check whether the motor shell is reliably connected with the frame. ④ Replace the motor or driver. |
| SPEEd | ① Check whether the power line and hall line of the motor are connected reliably and correctly, and whether the motor is locked. ② Replace the motor. ③ Replace the drive. |
| YArn (yarn breaking fault) | ① Broken yarn stops, please connect the yarn and restart. (Press the shift key to clear the fault). ② The number of yarn strands is set incorrectly. ③ This fault will be reported when the yarn often jumps out of the yarn breaking sensor. Setting the yarn breaking response time can solve this problem. ④ Alarm during startup, please set the yarn break delay detection time longer. ⑤ Replace the broken yarn sensor. ⑥ Replace the operation box |
| Yarn overlapping and stemming | ① The swing can be increased appropriately. ② Adjustable acceleration and deceleration time, and holding time. |
| Incorrect yarn length | ① Too high slip coefficient between grooved drum and yarn. ② The perimeter of the grooved barrel or the diameter of the grooved barrel is set incorrectly. ③ Motor speed and setting speed are incorrect. ④ Modify the length factor. |
| The whole machine cannot be started | ① Touch screen motor speed is not set ② The machine is locked and needs to be unlocked by the manufacturer |
| Fault phenomenon | Causes and solutions |
| Inaccurate yarn weighing | ① Determine whether the electronic scale and standard weight are accurate: 1. If they are not accurate, calibrate the electronic scale again; 2. If they cannot be calibrated for many times, replace the electronic scale; 3. If the weight value of the electronic scale changes and is unstable, replace the electronic scale. ② The electronic scale is accurate in weighing and inaccurate in weighing: 1. Whether the electronic scale is placed horizontally; 2. Whether the yarn on the scale shakes greatly during the working process; 3. Frequent yarn breakage will also lead to inaccurate weighing. |
