Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00355565 (model designation 33.8104-E) is a 2.2 kW AC frequency inverter engineered for precise motor speed control within the Lenze 8100 Series. Powered by either a single-phase or three-phase 230 V AC supply (180 to 264 V AC), the drive provides a three-phase output up to 9.5 A continuous current across an adjustable output frequency range of 0 to 480 Hz. Housed in an IP20 enclosure, the 33.8104-E integrates a Class E EMC filter that provides internal radio interference suppression to meet European electromagnetic compatibility requirements without requiring external filter modules.
Integration into automated machinery relies on terminal I/O combined with serial communication options. The drive features four programmable digital inputs, one digital status output, a multi-function analog input (0–10 V or 0–20 mA), and one analog output (0–10 V). To put a spare inverter into service, operational parameters stored in non-volatile EEPROM memory must be matched to the system using front keypad programming or transferred via Lenze Global Drive Control (GDC) software over an optional LECOM-A (RS232 module 2102IB / 33.2102) or LECOM-B (RS485) module. ABC Industrial Parts supports parameter backup extraction and spare-part commissioning to ensure smooth replacement in operating production lines.
System status monitoring and fault isolation are handled via an onboard 4-digit 7-segment LED display, which shows operational frequency, parameter numbers, and active TRIP error codes. Fault codes indicate specific trip conditions such as power stage short circuits (OC1), ground faults (OC2), overloads (OC5), DC link overvoltage (OU), DC link undervoltage (LU), heat sink overtemperature (OH), and serial communication faults (CE0). Initial troubleshooting involves verifying line voltages, checking motor insulation, cleaning heat sink cooling fins, and validating interface connections. When power stage or internal controller failures occur, field repair is not feasible, making a fully tested replacement or repair through ABC Industrial Parts the most practical solution to restore operation.

Programming and Configuration
Parameterization of the Lenze 00355565 inverter is executed directly using the front keypad or through Lenze Global Drive Control (GDC) software. Key configurable parameters include V/f characteristic curve selection (linear or quadratic), slip compensation, torque boost, acceleration/deceleration ramp times, and terminal I/O assignments.
The drive utilizes non-volatile EEPROM memory to preserve parameter configurations permanently, even during power interruptions. When installing a replacement unit, parameter sets can be entered manually via the keypad or extracted and uploaded via GDC software to ensure identical operation to the original drive.
Communication and System Integration
The 33.8104-E frequency inverter integrates with control hardware through dedicated control terminals and serial interface accessories. Hardwired control relies on four programmable digital inputs, one digital status output, a multi-function analog input (0–10 V or 0–20 mA), and an analog output (0–10 V).
To enable network integration or software diagnostics, optional plug-in communication adapters are available. The LECOM-A RS232 module (2102IB / 33.2102) connects directly to diagnostic computers, while the LECOM-B RS485 adapter supports multi-drop serial networking with supervisory PLCs and host controllers.
Diagnostics and Status Indication
Real-time operational monitoring is provided by the integrated 4-digit 7-segment display located on the front panel. During standard operation, the display outputs the active output frequency and selected parameter values. When a fault occurs, the display automatically switches to display active TRIP codes for rapid error identification.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| 4-digit 7-segment LED display | Active Display | Displays output frequency, current parameter numbers/values, and active TRIP error codes. |
Replacement and Spare Part Considerations
When replacing a Lenze 00355565 drive, verify that the replacement match matches the 33.8104-E model designation. It is vital to confirm the 2.2 kW power rating, 9.5 A current output, 230 V AC supply range, and the Class E filter designation to ensure compliance with system wiring and EMC standards.
Replacement drives are not plug-and-play. Parameter settings stored in the original unit's EEPROM memory must be loaded into the spare drive before running the motor. If the faulty unit allows communication, parameter sets can be downloaded using Global Drive Control software via a LECOM adapter; otherwise, parameter parameters must be manually entered according to machine records.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short circuit | Short circuit on motor output or earth fault detected during operation or acceleration. | Short circuit in motor winding or motor cable, insulation breakdown to ground. | Check motor cable and motor insulation resistance. If fault occurs without motor connected, internal power stage is damaged and unit must be returned for repair or replaced. |
| OC2 | Earth fault | Ground fault on motor side. | Motor cable or motor winding has ground contact. | Check motor cabling and motor for ground faults. |
| OC5 | Overload / I x t limitation | Drive current overload threshold exceeded. | Acceleration time too short, motor mechanically overloaded or blocked. | Increase acceleration time, reduce load, check motor sizing. |
| OU | DC link overvoltage | DC bus voltage exceeds maximum limit. | Deceleration time too short, excessive regenerative energy from motor, supply voltage too high. | Extend deceleration time, fit external brake module/resistor, check line voltage. |
| LU | DC link undervoltage | DC bus voltage dropped below minimum threshold. | Mains supply voltage too low, phase failure, power interruption. | Check mains line voltage, line fuses, and wiring connections. |
| OH | Heat sink overtemperature | Heat sink temperature exceeded limit (> 85 °C). | Ambient temperature too high, cooling fan defective or clogged, insufficient clearance. | Clean heat sink fins, check cooling fan, ensure adequate cabinet ventilation. |
| OH4 | Motor overtemperature | Motor thermistor (PTC) triggered. | Motor overloaded, motor cooling insufficient. | Allow motor to cool down, reduce load, check motor ventilation. |
| EEr | EEPROM memory fault | Checksum error in non-volatile parameter memory. | EEPROM corruption or hardware failure. | Perform factory parameter reset. If fault persists, non-volatile memory hardware failure requires unit repair or replacement. |
| Er | Control electronics error | Internal hardware or micro-controller fault. | Internal electronic component failure. | Cycle mains power. If fault persists, internal hardware defect requires returning unit for service or replacement. |
| LP | Mains phase failure | Loss of one phase on AC input supply. | Blown fuse on input phase, loose supply wire. | Check input power fuses and line supply wiring. |
| CE0 | Communication error | Interruption in serial LECOM interface communication. | Communication cable disconnected, baud rate error, master offline. | Check LECOM cable connections, baud rate parameters, and master controller status. |
Frequently Asked Questions
How are parameters transferred to a replacement Lenze 00355565 inverter?
Parameters can be entered manually using the keypad or downloaded electronically using Lenze Global Drive Control (GDC) software via a LECOM-A (RS232) or LECOM-B (RS485) communication module. Settings are saved in non-volatile EEPROM memory.
