• I/O layout: Built-in isolated digital input/output for coolant pump, spindle, door safety interlock, limit switch and fixture control

4. Environmental Requirement

• Operating ambient temperature: 5℃ ~ 40℃ inside machine workshop; storage: -20℃ ~ +70℃

• Humidity: 10%~85%RH non-condensation; isolate from cutting fluid mist, corrosive gas and heavy vibration

5. Standard PCB Replacement Procedure (For Yaskawa Control Boards)

1. Cut off total 3-phase AC main power of machine, wait over 15 minutes for servo drive capacitor full discharge before cabinet disassembly.

2. Mark all flat bus cables, DC24V wiring and field I/O cables connected on target PCB (MORI-04/XSU02 etc.) before unplugging connectors.

3. Remove fixed screws of faulty circuit board, install tested replacement board into original cabinet slot and lock fastening screws.

4. Restore all wiring strictly following pre-marked labels, double-check no short-circuit on power terminals.

5. Power on machine, complete CNC self-diagnosis, load original machine parameters, perform single-axis jog test and dry-run of automatic machining program.

6. Common Fault & Troubleshooting

1. CNC alarm 310/322 servo ready error, axes cannot move: Inspect damaged XSU02 servo board, loose flat cable or defective MB20 main control PCB.

2. Emergency stop / safety door interlock invalid: Check blown fuse or burnt relay on MORI-04 I/O board.

3. Axis positioning overshoot during cutting: Troubleshoot aging servo encoder cable or faulty XC001B axis drive board.

4. Spindle/ATC no response: Measure DC24V supply voltage and corresponding I/O channel circuit of control board.
