Wysong circuit board
 |
Wysong 4003‑302 is an X/Y axis control board used in CNC shears and other industrial cutting machines. Common failures include burnt or tripped protection fuses on the power input, degraded MOSFETs or driver ICs that cause loss of motor current, and intermittent I/O faults where encoder signals are lost or misread. First‑check diagnostics: verify 24 VDC supply voltage and continuity to the board’s power terminals; inspect for visible component damage (burn marks, swollen capacitors) and test key MOSFETs with a multimeter; review any error codes displayed on the machine’s HMI for motor driver or encoder faults.[oss-gpt-20b] |
