This video demonstrates two new functions added to the SZGH 880TC CNC lathe controller — parameter modification history and key test — designed to improve traceability, maintenance efficiency and on-site diagnostics.
New functions explained:
✅ Parameter Modification History — every parameter change is automatically recorded with a timestamp; maintenance engineers can instantly review what was changed, when and by whom; eliminates guesswork when diagnosing machine faults caused by incorrect parameter settings; critical for multi-shift factories and CNC retrofit projects
✅ Key Test Function — verify every physical button and key on the controller panel in real time; instantly confirm whether a key press is registered by the system; speeds up fault diagnosis for unresponsive keys, panel damage or wiring issues during commissioning and after-sales service
Why these functions matter:
Faster fault diagnosis — no more manual parameter comparison; history log shows exactly what changed before a fault occurred
Safer parameter management — track unauthorized or accidental parameter changes across operators and shifts
Reliable panel verification — confirm full keypad functionality before machine delivery or after any panel repair
