YASKAWA CACR‑SR02AB2ER（SERVOPACK）
Description
1. SAFETY INFORMATION
High voltage: Risk of electric shock. Disconnect power ≥5 min before wiring/inspection.
Grounding: Always connect PE terminal to protective earth.
Overload: Do not exceed rated torque or duty cycle.
No modification: Unauthorized changes void warranty and may cause fire/injury.
Emergency stop: Provide external E‑stop to cut power immediately.

5.2 Basic Operation
Connect power, motor, encoder; verify wiring.
Set parameters（or use defaults）.
Apply PULS+SIGN for position control, or ±10V for speed.
Use FWD/REV to start/stop.
Monitor LED for speed/position or alarms.
6. FAULT CODES & TROUBLESHOOTING
| Code | Fault | Probable Cause | Action |
|---|---|---|---|
| 1 | Overcurrent | Short circuit, overload, wiring error | Check U/V/W; reduce load |
| 2 | Overvoltage | Regen energy too high, surge | Add regen resistor; check input |
| 3 | Undervoltage | Voltage drop, loose terminals | Check supply; tighten connections |
| A | Encoder error | Broken wire, loose connector | Check 5CN; reconnect/replace encoder |
| F | Overheat | Poor ventilation, fan failure | Clean heatsink; check fan |
| B/C | System error | Control board fault | Replace drive |
7. MAINTENANCE
Daily: Check LED, no unusual noise/heat.
Monthly: Clean heatsink/fan; tighten wiring.
Annual: Replace cooling fan（if noisy）; check capacitors.
Lifespan: Electrolytic capacitors ≈5 years; fan ≈3 years.
