Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00356851 (model 33.8105A.1F.60) is a 4.0 kW three-phase AC frequency inverter designed for variable speed control of standard AC induction motors within the Lenze 8100 series family. Operating across a mains supply voltage range of 380 V AC to 480 V AC, this drive delivers a continuous rated output current of 9.5 A and an adjustable output frequency spanning from 0 to 480 Hz. Motor control is maintained using standardized V/f characteristic curves, making it suitable for material handling, conveyor systems, industrial fans, pumps, and packaging machinery.
Field connections for control wiring and signal lines are implemented using a dedicated screw terminal strip for digital and analog I/O. The unit includes an integrated slot for plug-in expansion modules, allowing connectivity via LECOM RS232/RS485 serial communication or PROFIBUS-DP fieldbus interfaces to integrate directly into centralized PLC architectures. Commissioning a replacement unit requires matching motor and application parameters; parameter configuration can be performed using Global Drive Control (GDC) PC software or cloned quickly via the plug-in Lenze Operating Keypad module into the dual non-volatile internal EEPROM storage. ABC Industrial Parts can assist maintenance teams with parameter restoration and spare unit preparation to minimize machine downtime.
Operational monitoring and status feedback are handled through integrated front-panel LEDs alongside hardware signaling options. A green Operating Status LED indicates normal running condition or warnings, while a red Fault Status LED indicates active trip conditions. Detailed trip diagnostics are available through the keypad display, the GDC software error log buffer, or the dedicated TRIP relay contact. When internal hardware errors occur, such as EEPROM memory checksum failures, board-level faults cannot be serviced in the field; replacing the unit or utilising a fully tested exchange drive from ABC Industrial Parts offers a fast path back to operational capability.

Programming and Configuration
Parameter setup and drive configuration on the Lenze 00356851 inverter are carried out using Global Drive Control (GDC) PC software or via the plug-in Lenze Operating Keypad module. GDC software allows online parameterization, tuning of V/f characteristic curves, and access to internal diagnostic memory.
The inverter contains dual non-volatile internal EEPROM storage, enabling two distinct parameter sets to be stored directly on the drive. When installing a replacement unit, the plug-in keypad can be used to copy complete parameter profiles from a running drive and download them directly into the spare unit without requiring a dedicated PC connection.
Communication and System Integration
The Lenze 8100 series 33.8105A.1F.60 frequency inverter features a control terminal strip with screw terminals for hardwired digital inputs, digital outputs, and analog reference signals. Hardware integration with automated systems is further supported by an onboard TRIP relay contact that provides status output signals to higher-level controllers.
For network integration, the drive contains a dedicated LECOM option slot. Depending on application requirements, this slot accepts plug-in LECOM RS232/RS485 modules for point-to-point or multi-drop serial communication, as well as plug-in PROFIBUS-DP fieldbus modules for integration into central PLC automation networks.
Diagnostics and Status Indication
The front panel of the Lenze 00356851 inverter includes visual LED indicators to quickly identify operating conditions. A green LED communicates overall operational status, staying solid during normal running and flashing when a warning threshold is reached. A red LED illuminates solid when a trip fault has occurred, bringing the inverter to a safety stop.
In addition to visual LEDs, diagnostic information can be evaluated using the plug-in Operating Keypad display, which presents active trip error codes. Maintenance personnel can also analyze the error log buffer using Global Drive Control (GDC) software or monitor the status of the hardwired TRIP relay contact.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Operating Status | Green - Solid / Flashing | Solid = Normal operation / ready; Flashing = Warning or operational status |
| Fault Status | Red - Solid | Trip fault present |
Replacement and Spare Part Considerations
When replacing a failed drive in an existing panel, verify that the replacement match carries part number 00356851 and model designation 33.8105A.1F.60. Confirming the rated power (4.0 kW) and supply voltage specifications (380-480 V AC) ensures full hardware compatibility with existing control cabinets, line reactors, and external braking resistors.
Installing a spare 8100 series drive requires transferring application parameters. This can be accomplished by uploading parameter profiles from the original unit via Global Drive Control (GDC) software or by utilizing the Operating Keypad to clone the parameter set into the replacement drive's internal EEPROM. Verify fieldbus node addresses, DIP/rotary switch settings, and module seating on optional LECOM or PROFIBUS communication cards prior to restarting production.
While the 00356851 drive serves as an immediate, direct replacement for legacy installations, long-term system modernization pathways exist. Direct migration strategies are available to modern Lenze 8200 Vector or Lenze i550 series frequency inverters when upgrading machine control architecture.

The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Overcurrent during acceleration | Output current exceeds threshold limit during acceleration phase. | Acceleration time set too short; motor winding or cable short circuit; motor overloaded or stalled. | Increase acceleration time ramp; check motor power wiring and cable insulation; check motor sizing. |
