Lenze E82EV402K4C 8200 vector Frequency Inverter 4.0 kW 400 V

Lenze 8200 vector at 4.0 kW, 400 V

If a 4.0 kW (5.4 hp) induction motor has to run from a 3/PE 400 V supply, the Lenze E82EV402K4C is the 8200 vector frequency inverter that the catalogue assigns to that rating. The base controller holds the power stage; function modules and a keypad are added to it. Note that the 8200 vector sits under previous products on the Lenze website. Ratings come from the 11/02 Lenze catalogue, an older edition, and should be verified with the supplier before an order is placed.

Technical specifications

Reading the type code E82EV402K4C

Breaking the code down: E82EV means 8200 vector base controller; 402 stands for the 4.0 kW rating; K4C is the 400 V supply class. The stem alone does not say whether an EMC filter is built in: suffix 0xx does, 2xx does not, and the catalogue prints both.

Choosing and installing this size

Most installations combine it with function module E82ZAFSC010 as the I/O interface and may add the EMZ9371BC keypad. Always compare the motor’s rated current with 9.5 A, because kW alone can mislead. Raising the chopper frequency to 16 kHz limits the current to 6.1 A. A mains choke is optional and lowers the mains current to 8.8 A. Above +40 degrees C reduce the rated current by 2.5% per degree, and above 1000 m altitude by 5% per 1000 m. Install it in vertical position and leave a 100 mm gap above and below the housing.

The catalogue’s control data apply to every size. The controller offers V/f characteristic control, linear or quadratic, as well as vector control with torque provision. Maximum torque is 1.8 times the rated motor torque for 60 s when the motor rating equals the drive rating. In sensorless speed control the setting range is 1:50 related to 50 Hz and rated torque, with an accuracy of plus or minus 0.5 percent and a minimum output frequency of 1.0 Hz. Digital setpoints are accurate to plus or minus 0.005 Hz, and the analog inputs use a 10-bit converter. At 4.0 kW these figures combine with the 9.5 A rating above.

Where it sits in the range

Neighbours in the 400 V class are given by the type tables: the next size down is 3.0 kW (E82EV302K4C) and the next size up is 5.5 kW (E82EV552K4C).

Documentation and quotation

Ratings, mounting drawings and accessories are in the attached Lenze catalogue, edition 11/02, which should be checked against the nameplate. More inverters are shown in AC Drives. Quote requests need the whole part number with suffix, the voltage and motor nameplate details; availability should be confirmed before ordering.
