Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00386351 (type EVF8102-A, ordering designation 33.8102A.2A.60) is a compact 0.75 kW frequency inverter from the Lenze 8100 Series, engineered for speed regulation of standard three-phase AC induction motors. Designed for cabinet panel mounting, this drive operates on a single-phase or three-phase 230 V AC mains connection within an acceptable voltage window of 180 V AC to 264 V AC. It provides a continuous output current of 4.0 A at 230 V AC, supporting motor output frequencies from 0 Hz up to 480 Hz with an adjustable switching frequency up to 8 kHz to minimize motor noise. The drive is widely deployed across packaging machinery, material handling systems, textile equipment, conveyor drives, pumps, fans, and machine tool spindles.
Control integration is supported by four programmable digital inputs, one transistor digital output, one analog setpoint input supporting 0-10 V or 0/4-20 mA signals, and one 0-10 V analog monitor output. Built-in network connectivity is expandable via a dedicated communication slot that accepts modular LECOM fieldbus adapters for RS232, RS485, or fiber optic interfaces. Commissioning a spare drive requires restoring the application parameter set stored in non-volatile internal EEPROM memory. Parameter transfers and drive setup can be accomplished using the plug-in EMF2101IB operating keypad module or Lenze Global Drive Control (GDC) engineering software. ABC Industrial Parts can assist maintenance teams with pre-tested replacement units and parameter backup migration to minimize installation downtime.
Front-panel status LEDs provide immediate operational status, featuring a green LED for mains voltage and drive readiness alongside a red TRIP LED indicating active fault states. Detailed diagnostic codes and parameter monitoring are accessible through the optional EMF2101IB keypad or via GDC software over a LECOM communication link. Recommended maintenance checks include verifying mains voltage, checking motor winding resistance and cable insulation, ensuring heatsink airflow, and inspecting fieldbus cabling. Persistent hardware faults or unrecoverable EEPROM checksum errors require specialized repair or unit exchange, where ABC Industrial Parts provides efficient replacement options to keep production lines running.

Programming and Configuration
Parameterization of the Lenze 00386351 EVF8102-A frequency inverter is carried out using Lenze Global Drive Control (GDC) software or the optional EMF2101IB plug-in keypad module. Operating parameters control motor acceleration ramps, current limits, switching frequency adjustments up to 8 kHz, and I/O signal mapping. Drive configurations are held securely in non-volatile internal EEPROM memory, safeguarding parameters against power supply loss.
When commissioning a spare inverter, the stored parameter set must be transferred to match the operational settings of the driven equipment. Users can upload parameter files via GDC software using a LECOM communication adapter or directly save and copy parameters using the memory function on the EMF2101IB operating keypad module. This eliminates manual parameter entry and reduces replacement errors.
Communication and System Integration
The EVF8102-A provides onboard hardwired control terminals and a modular communication slot for direct integration into machine control architectures. Physical connections include four digital inputs, one digital transistor output, one analog setpoint input supporting voltage (0-10 V) or current (0/4-20 mA) modes, and one 0-10 V analog monitor output.
For serial fieldbus communications, the dedicated interface slot accommodates LECOM modular communication adapters. Depending on the installed LECOM module, the drive can interface over RS232, RS485, or optical fiber communication lines, enabling direct connections to higher-level controllers or monitoring PCs running Global Drive Control software.
Diagnostics and Status Indication
The front face of the EVF8102-A frequency inverter features status LEDs for quick visually accessible system status checks. A solid green Ready/Mains LED indicates that mains voltage is present within the valid 180 V to 264 V AC operating window and the inverter is ready for operation. A solid red Fault (TRIP) LED indicates that an active protection or fault condition has triggered a drive shutdown.
Detailed fault codes and operational diagnostics can be monitored using the plug-in EMF2101IB keypad module or via LECOM communication connected to GDC software. Transistor and relay trip outputs can also be wired to upstream controllers to signal fault states automatically.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready / Mains | Green - Solid | Mains voltage present and drive is ready for operation |
| Fault (TRIP) | Red - Solid | Drive active fault condition detected |
Replacement and Spare Part Considerations
When selecting a spare unit for the Lenze 00386351 EVF8102-A drive, match both the part number 00386351 and model type EVF8102-A (or 33.8102A.2A.60) to ensure exact mechanical and electrical interchangeability. Confirm that the replacement drive rated output matches 0.75 kW and 4.0 A continuous output current.
Because the EVF8102-A relies on stored configuration parameters in EEPROM memory, a replacement drive will not operate correctly out of the box without parameter transfer. Always backup settings from the failed unit using the EMF2101IB keypad or Global Drive Control software prior to decommissioning, then download the backup file into the replacement inverter.
While Lenze has introduced modern drive families such as the i510 and i550 series as long-term replacement paths, utilizing an exact Lenze 8100 Series replacement drive avoids control cabinet retrofits, rewiring, or PLC communication modifications.
