Yaskawa CACR‑SR02AB1ER‑Y1（SERVOPACK）
Description
1. SAFETY INFORMATION
High voltage warning: Risk of electric shock. Disconnect power before wiring/inspection.
Grounding: Always ground the drive and motor to avoid electric shock.
Overload/overheat: Do not exceed rated torque/duty cycle. Allow cooling time.
No modification: Do not modify the drive; voids warranty and may cause fire/injury.
Emergency stop: Provide external E‑stop circuit for immediate power cut.

6. FAULT CODES & TROUBLESHOOTING
表格
| Code | Fault | Probable Cause | Corrective Action |
|---|---|---|---|
| 1 | Overcurrent | Short circuit, motor overload, wiring error | Check U/V/W wiring; reduce load; check motor insulation |
| 2 | Overvoltage | Regenerative energy too high, input surge | Add regen resistor; check input voltage |
| 3 | Undervoltage | Input voltage drop, loose connection | Check power supply; tighten terminals |
| A | Encoder error | Broken wire, loose connector, encoder damage | Check 5CN wiring; reconnect; replace encoder |
| F | Overheat | Poor ventilation, fan failure, overload | Clean heat sink; check fan; reduce duty cycle |
| 4–7 | Reserved | — | — |
| B/C | System error | Control board failure | Replace drive |
7. MAINTENANCE
Daily：Check LED status, no unusual noise/heat.
Monthly：Clean heat sink/fan; check wiring tightness.
Annual：Replace cooling fan（if noisy）; check capacitor aging.
Lifespan：Electrolytic capacitors ≈5 years; fan ≈3 years.
