542: H axis no feedback
A. It may be that the communication line is incorrect, check the production and connection of the communication line.
B. The number of heads set is incorrect, and the number of heads set is more than the actual number of heads, so that the main board cannot query the relevant information of the extra heads.
C. The DIP switch address setting is incorrect.
503: H-axis motor overtime
A. Check whether the connection of the motor and the encoder is normal.
B. The fault caused by the mechanical stall of the motor.
C. The speed of towel embroidery is too high during embroidery, and the load is too heavy, resulting in overcurrent. The speed of towel embroidery should be reduced, and it should not exceed 650 rpm. If the actual speed exceeds the set speed, the spindle speed should be compensated or the transmission gear ratio should be adjusted. .
D. The spindle speed fluctuates too much, and the machine should be run in properly to make the speed stable.
555: Abnormal color change position
A. First check whether the power and ground of the color-changing potentiometer are reversed, that is, in the "color-changing position adjustment" interface, adjust in the upward direction, and the value of the color-changing potentiometer should increase.
B. Use a precision single-turn resistor, install it correctly, and ensure that the signal line of the potentiometer is far away from high-power modules and signal lines such as power supply and motor drive. The value of the potentiometer should float between ±1. Connect 104 capacitors between signal and ground.
C. When the thread loosening position falls from the upper position to the lower position, the shaking ring causes the hook position to be abnormal. Adjust the speed of the shaking ring, the angle of the shaking ring and the machine to ensure that the shaking ring will not cause the ring shuttle to move.

505: thread trimming motor timeout
A. Check if the proximity switch is connected correctly.
B. Whether the thread trimmer motor device works normally, see if there is any difficulty in the movement of the thread trimmer motor.
C. Check whether the installation meets the requirements of one 24V with three headboards.
The looping head does not loop or sometimes does not loop when looping
A. Check whether the communication line is made and connected correctly.
B. Check whether the 5-core and 6-core wiring of the communication line is correct, whether a terminal resistor is added, and it is necessary to ensure that the communication line is far away from high-power modules such as motor drive and power supply.
When embroidering, it can be embroidered for a while, and it can't be embroidered for a while
First check whether the electronic gear ratio is correct. The D/H axis parameters of centralized towel embroidery are not set correctly. At present, the default parameters of the D/H axis driver shipped by the company are PA1/PA2=250/9, and each pulse corresponds to 1 degree and needs to be modified. Into: PA1/PA2=250/10, each pulse corresponds to 0.9 degrees.
D or H axis error reported
If the D or H axis continues to rotate after the error is reported, it is a problem with the installation of the D/H axis origin detection proximity switch. You should check whether the proximity switch is damaged or whether the wiring of the proximity switch is correct.
If the D/H axis does not rotate, there is a problem with the wiring of the D/H axis signal line. You should check whether the D/H axis wiring and the drive are installed correctly.
Bad embroidery at low speed
When the lever is started or the lever is moved slowly, the embroidery is rather wooly. The poor embroidery is due to the timing coordination between the H-axis looping and the spindle at low speed. Modifying the "low-speed looping angle" can solve it.
Falsely reporting disconnection or not reporting disconnection
1. Check whether the broken detection block is flexible, and whether there are false alarms when wired.
2. Check whether the proximity switch is damaged.
3. The default value of the towel "disconnection sensitivity" parameter is "1". If there are many false alarm disconnection times, it can be increased. If no disconnection is reported, you need to first set the "disconnection sensitivity" to 1, and then adjust the disconnection detection Block position.
