Lenze E84AVSCE3734VX0 8400 Drive Unit

Module Feature

E84AVSCE3734VX0 belongs to Lenze 8400 StateLine C vector inverter series.

It supports V/F control and sensorless vector control, provides stable torque output at low speed. It has built-in application function blocks, optional CANopen and PROFIBUS communication modules. This drive is widely used in packaging machinery, conveying lines, fans and pumps in factory automation.

Working principle

Three-phase AC power is rectified into DC bus voltage, and the IGBT power stage outputs adjustable PWM AC.

The microprocessor executes vector algorithm to realize closed-loop current and speed control. It integrates multi-protection logic including overcurrent, overvoltage, phase loss, overload and overtemperature, and outputs fault signals to upper control system.

Onboard components

Rectifier bridge, IGBT power module, DC bus capacitors, current sampling circuit, control mainboard, cooling fan, terminal block and expansion slot.

LED indicators

Front LEDs show power supply, running status, alarm warning and fault code indication.

Hardware self‑diagnosis

Power-on self-test and continuous monitoring detect phase failure, overheating, DC bus out of range and communication error, fault information can be checked by local panel or engineering software.

Programming software

Lenze L-force Engineer, used for motor identification, parameter setting, logic configuration and fault record reading.
