Product Review
Core Specifications
This unit belongs to Lenze 8200 Vector series. Its rated power reaches 5.5 kW for general industrial drive.
It accepts 3-phase 380–480V AC input at 50/60Hz. The output current is 13A with maximum 19.5A.
It supports V/f control and vector control modes. It offers 150% overload capacity for 60 seconds.
The inverter is rated IP20. Its overall dimension is 200×175×190 mm and total weight is about 3 kg.
It is equipped with built-in brake transistor and RS485 interface for basic communication.
It also provides four sets of parameter groups and integrated PID controller.
Key Advantages
Vector control delivers high torque at low speed for smooth heavy-load startup.
Compact structure fits installation in cabinets with limited inner space.
It allows expansion of communication modules to connect with various automation systems.
Multiple protection functions secure the inverter and connected motors during operation.
Industrial grade design ensures stable performance for long-term continuous running.
Limitations
This model has no built-in EMC filter. Extra filter is required for strong interference environments.
Dust, oil and high ambient temperature will shorten its service life obviously.
Module-level faults demand professional tools and firmware support for effective repair.
Typical Applications
It is widely used to drive conveyors, fans, pumps and packaging machinery on production lines.
Usage Guide
Pre-installation Checks
Keep ambient temperature between 0°C and 40°C. Avoid dust, moisture and corrosive gas.
Install the unit vertically. Reserve over 100 mm clearance on top and bottom for heat dissipation.
Verify 3-phase input voltage within 380–480V range and balanced power supply.
Standard Wiring
Connect main power lines L1, L2, L3 to AC power source. Link U, V, W terminals to motor.
Fasten PE terminal for reliable protective grounding. Wire digital and analog I/O as required.
Use single-end shielding for signal cables. Connect RS485 terminals for communication links.
Commissioning Steps
Power on the inverter first. Enter menu to set motor nameplate parameters.
Run automatic motor tuning to optimize vector control performance.
Set acceleration and deceleration time as well as operating frequency limits.
Configure I/O and communication parameters, then save all settings.
Run the motor with no load. Check rotation direction, speed, temperature and noise.
Maintenance & Repair Methods
Regular Maintenance
Clean heat sink and cooling fan with dry compressed air every month.
Retighten all terminals of main circuit and control circuit regularly.
Test insulation resistance of motor and cables. The value shall be above 1 MΩ.
Replace cooling fan timely if it makes abnormal noise or stops working.
Check DC bus capacitors quarterly. Replace bulged or leaking capacitors at once.
Back up key parameters via keypad or L-force Engineer software periodically.
Common Faults & Solutions
OL1 / OL2 Overload
Possible causes include excessive load or improper motor parameters.
Extend acceleration time and redo motor tuning to solve the problem.
OH / OH4 Overheating
Poor ventilation, high ambient temperature or faulty fan will trigger this alarm.
Clean dust and improve heat dissipation. Replace damaged cooling fan.
OU1 / OU2 Overvoltage
High input voltage or frequent brake operation leads to overvoltage.
Adjust power supply or install external brake resistor for long cable runs.
LU Undervoltage
Power phase loss, low voltage or aging capacitors cause undervoltage faults.
Inspect power lines and replace degraded DC bus capacitors.
CE Communication Error
Wrong wiring, defective module or conflicting address breaks communication.
Check cable connection, replace faulty module and reset communication address.
LP1 Motor Phase Loss
Loose terminals, broken wires or damaged contactor result in phase loss.
Inspect the whole motor circuit and fasten all loose connections.
FAn1 Fan Fault
Fan stall or broken internal wire activates fan protection alarm.
Check wiring and replace the faulty cooling fan directly.
Safety Warnings
Do not disassemble power modules or mainboard without professional training.
DC bus capacitors retain high voltage. Cut off power fully before any maintenance.
