Lenze E84AVSCE2234VX0 8400 StateLine C Frequency Inverter Unit

Module Feature

E84AVSCE2234VX0 is a rack-mounted variable frequency drive of Lenze L-force 8400 StateLine C series.

It is built with conformal coated circuit board for dusty, humid industrial environments. It supports asynchronous motor vector control and V/F control. Integrated EMC filter, brake chopper interface and STO safe torque off are standard. It has internal function block for simple logic without external PLC, supports preset speeds and PID closed-loop process control. It is widely stocked as spare for material handling, water treatment, packaging machine and HVAC control cabinets.

Working principle

Three-phase AC input is rectified to DC bus, then IGBT inverter outputs adjustable voltage and frequency.

The main control board samples voltage, current and motor status continuously, adjusts output according to setpoint. Regenerative energy during deceleration can be dissipated via external braking resistor. The STO circuit cuts off drive pulse safely for emergency stop requirements. It monitors overcurrent, overvoltage, overheat, earth fault and motor loss, and sends alarm via digital output or fieldbus.

Onboard components

Input rectifier assembly, IGBT power module, coated main control PCB, voltage & current sensing circuit, built-in EMC filter, cooling fan, front keypad, STO safety circuit and metal chassis.

LED indicators

Front LEDs indicate power, run, fault, alarm and communication status.

Hardware self‑diagnosis

Drive continuously monitors heat sink temperature, DC bus voltage, output current and STO circuit integrity. Parameters can be modified on local keypad or PC software.

Programming software

Lenze EZ-Software / L-force Engineer, used for motor parameter setup, I/O mapping, communication configuration, fault trace and firmware upgrade.
