The thermal relay is activated, and the protection switch is turned off first, and then check whether the power supply line is missing phase; check whether the motor is overloaded, and then power on again after the check. Replace the fuse. Check and repair the spindle motor. The spindle motor is faulty. Check whether the power input terminal is lack of phase.
If there is a lack of phase, use a voltmeter to Tubular Embroidery machine Exporters measure the input power voltage and repair. Check whether the connector on the main shaft control board of the embroidery machine is firmly connected. Replace the spindle control board.
There is a problem with the spindle control board.Computer embroidery machine error display: spindle motor timeout Computerized embroidery machine malfunction inspection, adjustment and judgment methods and troubleshooting methods: If the connector core is damaged, repair and replace the connector core. There is a problem with the main control board, replace the main control board. The 3A fuse on the spindle control board is blown Check whether the 12V power supply of the needle position detection board is normal. Check whether the connector on the needle position detection board of the embroidery machine is firmly connected.
If the ferrule is damaged, replace the damaged ferrule Observe whether the half-turn indicator on the needle position detection board is on, if it is not, measure the DC 12V switching power supply, if there is no output If the embroidery machine is abnormal-repair or replace the DC power supply.
If the problem listed in item 3 above still exists after replacing the needle position detection board, the main control board is faulty-replace the main control board If it is not displayed, or some positions are displayed and some positions are not displayed, the needle position detection Spray Printing Embroidery Machine Manufacturers board is faulty-replace the needle position detection board Error phenomenon of computer embroidery machine color changing error: Inspection, adjustment and judgment methodsTroubleshooting methods: Use the handle to turn the color-changing motor and linkage mechanism to observe whether the needle position indicator light changes accordingly. If it is abnormal, adjust the mechanical part Open the cover of the needle position detection board to see if the mechanical part is normal
