Lenze EVF9336-EVV060 Vector Drive Inverter Unit

Module Feature

EVF9336-EVV060 belongs to Lenze classic 9300 vector series cabinet type high-power frequency inverter. It supports V/F control and closed-loop vector control with encoder feedback, realizes high torque output at low speed. This variant is equipped with EVV060 option configuration, integrated RFI EMC filter, suitable for industrial heavy load continuous operation scenarios. It has rich onboard I/O, CAN system bus, and can expand PROFIBUS, encoder feedback interface. Widely used in extruders, large conveyors, mixers, papermaking and metallurgy main drive systems.

Working principle

Three-phase AC mains input is rectified into DC bus voltage, then IGBT power unit outputs adjustable frequency and adjustable voltage three-phase AC. Closed-loop vector algorithm calculates motor flux and torque separately according to encoder feedback signal, realizes high-precision speed and torque control. Built-in brake circuit interface can match external braking resistor for rapid deceleration.

Onboard components

Three-phase rectifier bridge, IGBT power module, DC bus capacitor bank, drive control motherboard, encoder feedback interface, CAN communication circuit, digital and analog I/O terminal block, EMC filter assembly, cooling fan group, operation panel interface.

LED indicators

Front panel has power, run, fault, alarm LED indicators; the matching operation keypad can display running frequency, current, fault code and parameter group.

Hardware self‑diagnosis

Power-on self-check covers overvoltage, undervoltage, overcurrent, over-temperature, motor overload, encoder signal loss, communication failure. Fault codes are stored in drive memory for query.

Programming software

Parameter configuration, commissioning and fault diagnosis adopt Lenze Engineer software; local parameter modification via EMZ9371BC keypad.
