More than 4 can not be resolved on the replacement card engraving machine fault diagnosis and troubleshooting
HGV Engraving Machine Faults Judgment and Troubleshooting - High Noise 1-1. Spindle Motor Running Noise - Spindle Bearing Quality Decrease or Damage 1-2. X-Axis Walking Large Noise - X-Direction Motor Bearing Damage or X-Direction Rail Slider Oil-free, dirty, too tight, ball wear, ball drop.
1-3. Normal noise: There is a pause for each step of the stepper motor, and it is normal to have some noise. At a certain frequency, it will also cause the body to resonate and produce significant noise. However, this noise will not affect normal use.
2. The axis is seriously lost. The X, Y, and Z axis stepper motors are each driven by two dedicated chips. For example, if one of the axis drive chips does not adhere to its heat sink, the temperature rise will be too high. The chip temperature exceeding 105 degrees Celsius will automatically protect the breaking current. When the temperature decreases, the current recovers again. Such a cycle continues. At this time, you can hear the vibration sound of the shaft. At this point regardless of the manual or output data, the axis will stop when the time and seriously lost their steps.
4. After the main power is turned on, the inverter is on and the control box is not responding. a. The fuse outside the control box is broken. b. The fuse in the switching power supply is off.
c. Poor contact of the control box three-core power cord plug;
5. After the main power is turned on, the inverter lights, the spindle manual/remote control switch is turned to the right, and the spindle is not responding.
a, The inverter is not in operation; b, The potentiometer is bad; c, The wiring in the inverter controller falls off; d, The cable from the inverter to the spindle motor is not connected or disconnected.
6. After the main power is turned on, turn on the power switch of the control box, the liquid crystal display is normal, the reset light is on, and the X, Y, Z three lights are on, but no response occurs.
37-core cable plug is not inserted;
7. The spindle motor stops suddenly and the inverter displays ERR 01, ie the phase is missing; or the motor is energized with a humming sound, but it does not rotate:
Possible causes 1. Spinning of the lead wire in the spindle motor; Confirmation method: Multi-meter meter spindle motor socket Three-core resistance. Solution: Remove the socket and reweld the open wire.
Possible reason 2. The three-wire cable connector of the spindle motor to the inverter is not connected properly. Solution: Re-plug or reconnect and try again.
Possible reason 3, Spindle motor to frequency converter three-wire cable disconnection, confirm method: Measure the amount of resistance between the two ends of the cable plug, the solution: Connect the disconnection line or replace the line.
8. If the spindle motor stops suddenly, the inverter displays ERR 05, or ERR 07, which is an overvoltage. If ERR 06 or 08 is displayed, it is an undervoltage. Check whether the 220V power supply is normal and stable. Speeding down or shutting down too quickly can also cause excessive internal voltage to cause alarms and shutdowns.
9. The spindle motor suddenly stops and the inverter displays ERR 13 or ERR 09.
ERR 09 is long-term overload, ERR 13 is over-current; Probable causes 1 , large cutters are too deep; Probable causes 2; Inverter is set incorrectly;
10. The spindle motor suddenly stops and the inverter displays ERR 16 . ERR 16 is a short circuit; Probable causes 1 , Short circuit between the three core motors of the spindle motor or a short circuit to the housing. Possible cause 2. Short circuit of the main shaft motor to the inverter tri cable or cable plug;
11. The spindle motor parameters of the machine and the frequency converter set the spindle motor power: 1200W; maximum speed: 42000RPM
Operating voltage at 42000 RPM: 220V
Operating voltage at 24000 RPM: 170V
One: One or three axes do not move or move abnormally 1: The control card is loose or faulty.
