Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 33.8106E, designated by model number EVF8106-E, is a 2.2 kW (3 HP) frequency inverter belonging to the Lenze Global Drive 8100E product family. Operating from a nominal 230 V AC supply across an input range of 180 V AC to 264 V AC, this drive delivers up to 9.5 A of continuous output current to regulate speed and torque in three-phase AC induction motors. Housed in an IP20 enclosure, the unit features an output frequency range of 0 to 480 Hz, making it capable of handling standard industrial motor tasks as well as high-speed applications. Dual control functionality allows users to choose between standard V/f characteristic control and open-loop vector control for enhanced torque performance at lower operating speeds.
Integrating a replacement inverter into an established machine system requires precise alignment of physical connections and parameter configurations. The 33.8106E incorporates an integrated terminal strip for digital inputs, analog reference signals (0–10 V or 0–20 mA), and programmable relay outputs, alongside an option card header for modular communication cards. Configuration parameters are stored in non-volatile internal EEPROM memory capable of retaining four independent parameter sets. When installing a replacement unit, settings can be transferred using an optional 8101 operating keypad module or via Lenze Global Drive Control (GDC) engineering software. Assistance with configuration transfer and parameter extraction from donor hardware can be facilitated through ABC Industrial Parts when putting a spare drive into service.
Operational diagnostics are displayed directly on the drive via an integrated dual-color Red/Green OPERATING / TRIP LED that indicates run states, warning status, and fault conditions. Detailed troubleshooting and TRIP fault history logs are accessible via parameter code C0161 using the 8101 keypad or GDC software. First-line field checks should verify main supply voltage stability, motor cable integrity, and fieldbus connections. When severe fault indications such as output short circuits (OC1), ground faults (OC2), or EEPROM memory errors (EE) persist after external wiring and settings are verified, internal power stage or control board component failure is indicated. As internal circuit board issues are not field-serviceable, acquiring a tested exchange unit or utilizing repair services via ABC Industrial Parts offers a fast path back to active production.

Programming and Configuration
Parameter setting and drive commissioning on the Lenze 33.8106E frequency inverter can be carried out locally using the plug-in 8101 Operating Module keypad or remotely through Lenze Global Drive Control (GDC) PC software. The inverter contains internal EEPROM memory engineered to store up to four complete parameter sets, providing flexible memory management for machines requiring multiple operating routines.
During routine replacement or setup, parameter sets stored on the drive can be duplicated or backed up to prevent configuration loss. If parameter data becomes corrupted or unreadable, executing parameter code C0002 resets the inverter to factory defaults, permitting clean parameter reentry for motor parameters, control modes, and ramp times.
Communication and System Integration
The 33.8106E inverter incorporates a integrated terminal strip providing physical I/O interfaces for process control. This includes configurable digital inputs for startup and control commands, analog inputs supporting 0 to 10 V or 0 to 20 mA reference signals, and programmable relay contacts for operational feedback.
For integration into broader fieldbus networks, the drive includes a modular expansion slot that accepts plug-in communication modules. Supported protocols include PROFIBUS-DP, CANopen, and LECOM serial interface modules such as the EMF2102IB (RS-232/RS-485). Network integration allows status word monitoring and remote parameter adjustments directly from a master PLC.
Diagnostics and Status Indication
Drive diagnostic state on the Lenze 33.8106E is indicated via an integrated dual-color Red/Green OPERATING / TRIP LED. Solid and flashing illumination patterns inform technicians of current drive activity, warning conditions, or active TRIP system shutdowns.
Advanced diagnostic inspection is available using parameter code C0161, which provides a TRIP fault history log. Status word conditions can also be read online via Global Drive Control (GDC) software or on the display of an attached 8101 keypad module.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| OPERATING / TRIP LED | Red/Green - Solid / Flashing | Indicates drive operating state, warning conditions, or TRIP status |
Replacement and Spare Part Considerations
Before installing a spare Lenze 33.8106E frequency inverter, confirm that the part number matches EVF8106-E and that the unit matches the 230 V AC input supply and 9.5 A current capacity requirements. Installing an unconfigured drive directly out of storage will result in system operational errors.
Ensure that parameter files stored in the original drive's EEPROM are cloned using an 8101 operating keypad or re-loaded from GDC software backups. If fieldbus connectivity is used, physically transfer the communication option module (e.g., PROFIBUS-DP, CANopen, or LECOM) from the old inverter to the replacement unit to preserve network settings.
In system retrofits or modernization scenarios, the Lenze i510 and i550 series inverters function as modern migration successors to the Global Drive 8100E line. Note that upgrading to an i510 or i550 unit requires re-mapping physical terminal connections and re-entering motor parameters within the newer software environment.
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 / Instantaneous overcurrent | Output current exceeded peak safety limit due to short circuit or severe earth fault. | Short circuit in motor cable or motor winding; earth fault; acceleration time too short. | Check motor and motor cable for short circuit or earth fault. Check ramp settings. If error persists with motor disconnected, internal power section failure — return unit for repair. |
| OC2 | Earth fault | Ground fault detected on inverter output terminals. | Insulation breakdown in motor or cable to earth. | Check motor insulation resistance and wiring. If fault occurs with cables disconnected, internal hardware fault — send drive for repair. |
| OC5 | Drive overload (I x t) | Drive continuous output current exceeded rating for extended period. | Mechanical overload; motor under-dimensioned; prolonged low speed operation under high load. | Reduce mechanical load; check motor sizing and duty cycle. |
| OU | DC bus overvoltage | DC bus voltage exceeded upper limit. | Deceleration ramp too short; excessive regenerative energy from load. | Extend deceleration time; install braking chopper / resistor if applicable. |
| LU | DC bus undervoltage | DC bus voltage dropped below minimum threshold. | Mains supply voltage drop or failure; phase loss; mains input fuse blown. | Check mains voltage supply and input wiring/fuses. |
| OH | Heatsink overtemperature | Inverter heatsink temperature exceeded maximum limit. | Inadequate cooling; ambient temperature too high; fan defective or clogged. | Clean heatsink cooling fins; verify enclosure ventilation; check cooling fan operation. |
| OH4 | Motor overtemperature | Motor PTC sensor triggered or motor thermal model reached trip point. | Motor thermal overload; inadequate motor cooling; PTC sensor cable damaged. | Allow motor to cool; check mechanical load; check motor PTC thermistor circuit. |
| EE | EEPROM memory error | Internal EEPROM memory read/write check failed during operation or startup. | Data corruption in non-volatile memory; internal control board fault. | Reload factory default settings (C0002) and reconfigure parameters. If error persists, internal control hardware fault — unit requires replacement or service. |
| CE0 | Communication error | Interruption in fieldbus or LECOM communication interface. | Loose connector cable; communication timeout; module failure. | Check fieldbus wiring, bus termination, and communication module connection. |
