Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 333643, model code 8102_E.4G.12, is a compact AC frequency inverter from the Lenze 8100 series designed for dynamic speed control of three-phase asynchronous motors. Engineered for panel mounting within control enclosures, this drive operates on a 3-phase mains supply from 400 V to 480 V AC across an operating range of 320 to 528 V AC. It delivers a rated output power of 0.75 kW with a continuous output current of 2.3 A. Built to IP20 protection standards, the inverter supports linear and quadratic V/f characteristic curve control over an output frequency range of 0 to 480 Hz. With adjustable switching frequencies up to 16 kHz, it provides low-noise motor operation suitable for material handling, packaging machinery, pumps, fans, and general industrial plant engineering.
Integrating the 333643 into an existing control system relies on flexible communication options and stored parameter profiles. The drive incorporates a modular extension slot that accepts option modules such as LECOM-A (RS-232), LECOM-B (RS-485), LECOM-LI (fiber optics), or PROFIBUS-DP fieldbus modules (types 2131 and 2133). Drive parameters are maintained in internal non-volatile EEPROM memory. Commissioning a replacement unit requires restoring the motor and application parameters rather than simply attaching power cables. Parameter sets can be backed up and cloned using the plug-in 2102 IB operating module keypad or transferred via Lenze Global Drive Control (GDC) commissioning software. Maintenance technicians working to restore system operation can rely on parameter extraction services from ABC Industrial Parts when parameter transfer from an existing drive or backup file is required.
Real-time operational status and trip states are reported directly via two front-panel LED indicators. A solid green LED indicates an operational state with the controller enabled, while a flashing green LED signifies active controller inhibit. A solid red LED signals an active fault trip, whereas a flashing red LED indicates an active warning or pending trip state. For detailed error analysis, fault codes can be read on the optional 2102 IB keypad or through the GDC diagnostic window, with historical fault events retained in parameter P168. First-line troubleshooting should include verifying three-phase mains supply voltages, checking motor terminals for short circuits or earth faults, and inspecting cabinet ventilation for thermal trips. When internal microcontrollers or control board hardware fail, field servicing of internal components is impractical, and a fully tested replacement unit from ABC Industrial Parts provides a direct route to minimizing downtime.

Programming and Configuration
The Lenze 333643 frequency inverter stores user parameters in internal non-volatile EEPROM memory, securing operational profiles against power loss. Drive setup and parameter editing are performed using either the plug-in 2102 IB operating module keypad or the PC-based Lenze Global Drive Control (GDC) software tool. Key adjustable parameters include acceleration time (P012), deceleration time (P013), and parameter set selection or reset functions (P002).
When commissioning a spare inverter, exact parameter alignment with the original unit is essential for proper motor response and application control logic. The 2102 IB keypad allows direct copying and transfer of full parameter sets between drives, enabling quick cloning on the factory floor. Alternatively, GDC software connects via LECOM communication adapters to upload, archive, and download complete configuration files or restore default factory settings when recovering from configuration errors.
Communication and System Integration
The 333643 inverter features a modular interface slot designed to integrate with fieldbus networks and serial communication adapters. Supported communication interfaces include LECOM-A for RS-232 serial links, LECOM-B for RS-485 multi-drop networks, and LECOM-LI for optical fiber connections. These adapters enable direct point-to-point or networked connection to higher-level controllers and host systems.
For fieldbus-driven automation environments, the drive accommodates PROFIBUS-DP fieldbus modules, including models 2131 and 2133. These interfaces allow full control word transmission, reference value setting, and diagnostic monitoring over PROFIBUS pipelines. Communication status and protocol timeouts can be monitored via connected master units or through the drive's internal diagnostic parameters.
Diagnostics and Status Indication
The front panel of the Lenze 333643 includes two multi-state status LEDs providing visual operational feedback. The green LED indicates drive run status and controller enable conditions, while the red LED alerts operators to active trip conditions or pending warnings. When equipped with the optional 2102 IB operating module, the keypad display presents alphanumeric error codes for precise fault identification, alongside access to the fault history register stored in parameter P168. Diagnostic data can also be monitored remotely via the GDC software diagnostic window.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Operation) | Green - Solid / Flashing | LIT = Controller enabled / operational state. FLASHING = Controller inhibit active (ready for operation). |
| Red LED (Fault/Trip) | Red - Solid / Flashing | LIT = Active fault trip present. FLASHING = Active warning / trip pending. Indicates drive trip state. |
Replacement and Spare Part Considerations
The Lenze 333643 (type 8102_E.4G.12) serves as a direct drop-in replacement for matching 8100 series frequency inverters, eliminating the need for enclosure modification or control panel rewiring. Before installing a replacement drive, verify that the physical panel space, input supply rating (3-phase 400V/480V AC), and rated continuous output current (2.3 A) match the original installation requirements.
Because replacement inverters are typically reset to factory parameter sets, the original configuration must be transferred before placing the replacement unit into operation. This includes setting motor parameters, V/f curve profiles, acceleration/deceleration ramps, and fieldbus communication settings. Transferring the stored parameter profile via a 2102 IB keypad or uploading a GDC software backup ensures seamless integration without disrupting connected control hardware.
