Guangshu CNC system GSK980M display garbled code fault repair.
Fault symptom 1: The system display screen automatically resets.
The machine tool works for a long time, the system overheats, so that the reset chip is damaged or unstable, and the replacement of the reset chip or the replacement of the motherboard 928tc is 809ic, and 980t is damaged by 810ic.
Fault symptom 2: The display screen is blue.
Frequently replace the motherboard with a blue screen, faulty display circuit or IC component.
Occasionally, there is a blue screen, the system overheats, or a dead loop program causes the system to reboot.
The brightness of the display screen is not adjusted, refer to the manual, and adjust the brightness.
Fault phenomenon 3: The display screen is garbled.
Cause of failure and treatment method:
If the internal connector of the system motherboard is faulty or the internal connector is in poor contact, replace the motherboard or send it to the factory for repair, if the internal connector is in poor contact, open the system and reconnect the connectors.
Fault symptom 4: The system does not display.
Cause of failure and treatment method:
The input voltage is abnormal, the system can not get the normal voltage check the 220V voltage input contact of the system to see if the 220V voltage is normal, if it is normal, then check whether the components of the power supply circuit are damaged, whether the contact between the contacts is good, and check whether the external voltage is stable.
If the power box is faulty, the power box voltage has no output, check whether the power box voltage is +5V, +12V, +24V, 12V is normal, if it is abnormal, the power box needs to be sent to the factory for maintenance.
The internal components of the system are short-circuited, resulting in abnormal voltage, and are sent to the factory for maintenance.
Check whether the external connection or threaded encoder is lowered by the +5V voltage, check the insulation of the circuit to the ground of the machine tool, and check whether the encoder plug is flooded or short-circuited by oil.
The internal display line is poorly contacted, open the system cover, and plug the connector from the reconnection.
Fault phenomenon 5: crash.
Cause of failure and treatment method:
Crash caused by 928tc program full (v2.)13v2.23 version) press the Enter and reset buttons at the same time, power on; Put the reset button first, wait for a while, and then put the enter key; Enter M8000, press Enter, and then"Enter 0 and press Enter";Repeat the input"0, Enter"six to eight times; Go to the program area, delete redundant programs, and free up space.
Crash caused by 928tc program full (v3.)Version 0) press the Enter and reset buttons at the same time, power on; Put the reset button first, wait for a while, and then put the enter key; Press 0,1,3,4, enter; Enter M8000, press Enter, press 1, then press the spindle high and low gear conversion key, Enter; And then"Enter 0 and press Enter";Note that this operation will delete all existing programs to free up space, so please make a backup.
External input and output lines, external cycle start buttons and other lines can cause the system to be in a state of panic Check the loop, eliminate the short circuit, and replace the components that cause the short circuit.
