⚠️ Notes:
- Terminal definition and parameter codes are incompatible with 8200; parameters must be re-commissioned.

- Mounting dimensions differ slightly; cabinet modification may be required.
- Typical Applications
Small conveyors, fans, pumps, compact packaging machinery, belt conveyors, simple spindle drives.
- General Operation Notes
- This model has no integrated brake transistor. An external brake unit must be used if brake resistors are required.
- An output reactor is recommended for long motor cables to suppress dv/dt and protect motor insulation.
- Factory default mode: V/F control. Activate vector control via parameters if required.

LENZE 8200 Vector Fault Code List (Applicable to E82EV Series including E82EV551_4C)
Display code | Internal No. | Fault Name | Causes & Troubleshooting
Distinguish TRIP faults (locked shutdown) and Warnings (continuous operation)
- Current-Related Faults (Most Common)
| Display Code | Internal No. | Fault Name | Causes & Troubleshooting |
| OC1 | 11 | Hardware Short-Circuit Fault (Hardware Overcurrent) | Inter-phase short circuit in motor cable, shorted motor winding, output earth short circuit; damaged IGBT |
| Troubleshooting: Power on with motor disconnected. If OC1 still occurs → inverter hardware failure; if fault disappears → motor/cable fault | |||
| OC2 | 12 | Earth Fault (Leakage to Ground) | Damaged motor cable contacting ground, breakdown of motor winding insulation; long cables without output reactor |
| OC3 | 13 | Overcurrent during Acceleration | Sudden load change, mechanical seizure, too short acceleration time, incorrect motor parameters |
| OC4 | 14 | Overcurrent during Deceleration | Insufficient deceleration time, high inertia load; DC bus fluctuation triggering overcurrent without brake resistor |
| OC5 | 15 | Overcurrent at Constant Speed | Heavy load fluctuation, seized bearing, motor phase loss, failed motor identification for vector control |
| OC6 | 16 | Motor I²t Overload | Prolonged heavy load, motor thermal overload; mismatched power rating |
| LP1 | 32 / 182 | Motor Phase Loss Detection (Active when C0597 enabled) | Loose wiring, open circuit of one motor phase; false alarm possible for low-power drives under no-load |
| Troubleshooting: Tighten terminals; adjust threshold C0599 |
- DC Bus Voltage Faults
| Display Code | Internal No. | Fault Name | Causes & Troubleshooting |
| LU | — | DC Bus Undervoltage | Low 3-phase supply voltage, input phase loss, poor contactors, voltage drop during power-up |
| ⚠️ E82EV551_4C has no built-in input fuse; prioritize checking upstream circuit breakers and terminals | |||
| OU | — | DC Bus Overvoltage | Rapid deceleration, regenerative energy from high inertia loads; excessive mains voltage; missing brake resistor |
| This model has no integrated brake transistor. An external brake unit + resistor is mandatory for frequent start-stop operation |
III. Overtemperature Faults
| Display Code | Internal No. | Fault Name | Causes & Troubleshooting |
| OH | 50 | Inverter Heatsink Overtemperature | Poor cabinet ventilation, ambient temperature >45℃; dust blocking cooling channels |
| E82EV551_4C adopts natural cooling without fan, highly dependent on ambient cooling conditions | |||
| OH3 | 53 | PTC Motor Overtemperature Trip | Overheated motor PTC thermistor; open/short-circuited PTC wiring; temperature monitoring enabled via C0119 |
| OH51 | 203 | PTC Overtemperature Pre-Warning | Motor temperature approaching protection threshold, advance warning |
| FAn1 | 95 | Fan Fault (Not applicable to this model! E82EV551 has no fan, this code will not appear) | Only applicable to higher-power models equipped with cooling fans |
- Communication Bus Faults (Only with optional communication modules)
| Display Code | Internal No. | Fault Name | Causes & Troubleshooting |
| Ce0 | 60 | LECOM Communication Fault (X500 diagnostic port) | Loose commissioning cable, damaged E82ZBC cable |
| Ce1 | 61 | CAN-IN1 Communication Fault | Faulty CANopen wiring, missing termination resistor, incorrect node address |
| Ce2 | 62 | CAN-IN2 Synchronous Communication Fault | Loss of bus synchronization signal |
| Ce5 | 65 | BUS-OFF Status | Severe bus interference or short circuit; drive automatically disconnects from bus |
| Action: Check shield grounding, 120惟 termination resistor and bus polarity | |||
| Ce6 | 66 | CAN Bus Timeout | No response from master station; communication monitoring time C0126 set too short |
- Parameter & Internal Hardware Faults
| Display Code | Internal No. | Fault Name | Causes & Troubleshooting |
| CCr | 71 | Controller Internal Fault | Severe electromagnetic interference, main control hardware damage |
| Test: Restore factory settings first; replace drive if fault persists | |||
| Pr0 | 75 | Damaged Parameter Set 0 | Parameter modified during power-off, EEPROM abnormality; restore factory settings C0002=10 |
| Pr1～Pr5 | 76～80 | Damaged Parameter Set 1~5 | Corrupted parameter bank; re-download parameters or perform factory reset |
| id1 | 140 | Invalid Motor Identification Data | Motor identification interrupted, motor disconnected; re-run motor identification C0148 |
| H05 | 105 | Hardware Detection Fault | Self-test failure of power board / drive circuit; hardware damage |
- External Control Status & Faults
| Display Code | Fault Name | Description |
| EEr | External Fault (Triggered via digital input) | External emergency stop or external fault terminal activated; check X3 external fault signal |
| QSP | Quick Stop Active | Quick stop terminal enabled; status message, NOT a trip fault |
| inh | Controller Inhibit | Enable condition not satisfied; no trip, drive cannot start |
Important Practical Tips for E82EV551_4C
- Distinguish status vs fault: inh, QSP, DCB are operating statuses, not trip faults and do not require reset. OC/LU/OH/CCr are trip faults requiring manual reset.
- Fault reset methods: RESET key on panel, bus command reset, power cycle.
- Fault history storage: Parameter C0084 Latest Fault, C0087 Previous Fault, C0088 Second Previous Fault for historical fault review.
- No-load test method: Disconnect motor cables and power on, to judge whether the fault originates from the inverter itself or external wiring/motor.
- This model has no built-in brake transistor. If OU overvoltage frequently occurs during deceleration, external brake unit is required.
