Description
Core Product Summary
The Lenze E84AVSCE3712SX0 is a 0.37 kW frequency inverter from the Lenze 8400 StateLine C range. It is a vector-controlled inverter for industrial speed-control applications, supplied from a 1/N/PE AC 230/240 V network and configured for installation mounting.
The drive provides a rated output current of 2.4 A and an output-frequency range of 0–599 Hz. Its product designation identifies a standard industrial environment version without integrated drive-based safety technology. CANopen is available on board, while the MCI slot accepts a Lenze communication module for fieldbus integration. Parameters are retained on the removable memory module, and commissioning can be performed locally through the diagnostic interface or through Lenze engineering software.

Detailed Product Overview
The Lenze E84AVSCE3712SX0 belongs to the 8400 StateLine C family of vector-controlled frequency inverters. It is intended for speed control and simple motion-control tasks in industrial machinery, where a compact 230 V single-phase supply is available. The model code identifies a 0.37 kW device in the 230/240 V voltage class, with standard industrial environmental protection and no integrated safety technology.
For integration, the inverter provides conventional hardwired control interfaces as well as CANopen communication. The control section includes digital inputs and outputs, an analog input and output, and a relay output. The factory pre-assignment uses the analog input for the main speed setpoint, digital inputs for functions such as fixed speed setpoints, DC-injection braking, and direction reversal, and the relay output for an error-pending status signal. These assignments can be reconfigured through the drive parameter set.
The unit has an integrated brake-management function and supports the Lenze “VFC eco” energy-saving function. It is suitable for drive tasks with or without speed feedback. The MCI communication slot allows a Lenze communication module to be fitted for protocols beyond the on-board CANopen interface, including EtherCAT, EtherNet/IP, POWERLINK, PROFIBUS, and PROFINET, subject to the appropriate module and system configuration.
Parameterization is stored in the removable memory module. This allows drive settings to be retained independently of mains power and transferred between compatible 8400 StateLine C units during maintenance or replacement work. Commissioning can be carried out with the Lenze keypad connected to diagnostic interface X6, with the EASY Starter software, or with Lenze Engineer. A USB diagnostic adapter and connecting cable are among the documented commissioning accessories.
The E84AVSCE3712SX0 is an installation-type IP20 device and must be installed in an appropriate electrical enclosure or control cabinet. It is a component for incorporation into a machine or electrical system rather than a standalone consumer appliance. Installation, protective earthing, EMC measures, cable sizing, fusing, and cooling must follow the applicable Lenze mounting and hardware documentation and local electrical regulations. Power terminals can remain live for several minutes after mains disconnection because of capacitor discharge, so isolation and discharge-time precautions are required before working on the power connections.
