Lenze 00450757 E82EV751_4B 0.75 kW Vector Drive
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00450757, model E82EV751_4B, is a 0.75 kW frequency inverter from the Lenze 8200 Vector product family. It is designed for variable-speed control of compatible three-phase motors in 3-phase 400/500 V AC systems, with a 0-400/500 V AC, 3-phase output. The drive has a rated output current of 2.4-2.6 A and supports a maximum periodic output current of 3.6 A, corresponding to 150% overload capacity.
The Lenze 8200 Vector uses a modular construction with a power unit, plug-in function/control module and operating keypad. For replacement work, the voltage class and current rating must match the installed drive, and a compatible function or control module may need to be transferred to the replacement power unit. Parameters can be backed up and restored through the XT Keypad or Lenze Global Drive Control software. Parameter storage uses internal EEPROM or a plug-in EJP memory module, with two parameter sets supported.
The XT Keypad displays error codes and provides local parameterization, while Global Drive Control supports parameterization, commissioning and diagnostics through the appropriate LECOM adapter. During troubleshooting, check the drive's displayed error information and the diagnostic register readout in Global Drive Control before returning a replacement to service. This discontinued frequency inverter is relevant for repair, exchange and spare-part requirements in installed Lenze 8200 Vector systems.

Programming and Configuration
The XT Keypad supports local operation, parameterization and parameter backup or restore. Parameters may be stored in the drive's internal EEPROM or in a plug-in EJP memory module, with two parameter sets supported.
Lenze Global Drive Control software supports parameterization, commissioning, diagnostics and parameter management through the appropriate LECOM adapter. Before commissioning a replacement, transfer the required parameter set and confirm that the installed plug-in function or control module matches the original 8200 Vector configuration.
Diagnostics and Status Indication
The XT Keypad displays error codes for local fault identification. Global Drive Control can be used for parameterization, commissioning and diagnostics, including diagnostic register readout through the appropriate LECOM adapter.
For a replacement drive, review the displayed error information and Global Drive Control diagnostic register before commissioning. Also confirm the voltage class, output-current rating, compatible plug-in function or control module and transferred parameter set.
Replacement and Spare Part Considerations
Use the exact Lenze part number 00450757 and model E82EV751_4B when identifying a replacement. The replacement must match the 3-phase 400/500 V AC voltage class, 0.75 kW rating and 2.4-2.6 A rated output-current range. The original compatible plug-in function or control module may need to be transferred to the replacement power unit.
A spare is not ready for operation until the required parameters and installed configuration have been restored. Parameter sets can be transferred with the XT Keypad or uploaded and downloaded using Global Drive Control and the appropriate LECOM adapter. Check the parameter storage method, including the internal EEPROM or plug-in EJP memory module, during planned maintenance.
The E82EV751_4B is discontinued and is therefore relevant to legacy-system repair, exchange and spare-part requirements. Lenze i500 or i550 products may be considered as successor options, but electrical, mechanical, control and module compatibility must be checked for the specific application before substitution.
Frequently Asked Questions
What is the Lenze 00450757 E82EV751_4B?
It is a 0.75 kW Lenze 8200 Vector frequency inverter for three-phase 400/500 V AC motor systems.
