Ensure the EC and FC firmware versions are compatible. Mismatches during individual board replacements can trigger spurious communication timeouts.
The variable frequency drive that regulates power to the hoist motor and manages regenerative braking.
| Blink Count | Error Type | Possible Cause | |-------------|------------|----------------| | 1 | Overcurrent | Short circuit in motor wiring, failed IGBT module | | 2 | Overvoltage | Regenerative power issue, brake resistor failure, mains surge | | 3 | Undervoltage | Low mains supply, blown fuse, DC bus undervoltage | | 4 | Overspeed | Brake slipping, encoder failure, drive parameter mismatch | | 5 | Overtemp | Cooling fan failed, ambient temp too high, overloaded | | 6 | Encoder loss | Loose connection, faulty encoder, broken cable shield | | 7 | Brake feedback | Brake not opening/closing properly, worn contacts or coil | | 8 | Door zone error | Magnet/sensor misalignment, bad door zone switch |
