E82EV251K2C200 Lenze 8200 Vector Drive, RS232/485, Brake Chopper

E82EV251K2C200 Lenze 8200 vector Frequency Inverter

E82EV251K2C200 is a Lenze 8200 vector built-in vector-controlled frequency inverter. It drives a 0.25 kW 4-pole asynchronous motor in the 230 V class. The unit delivers 1.7 A nominal output current at 8 kHz. It handles 0…650 Hz output frequency. This drive fits compact machines that need reliable speed and torque control. The C2xx variant ships without an integrated EMC filter. A built-in brake transistor is included. The 8200 vector family is a legacy line. Lenze confirms a migration path to the i950 series. The i950 emulates 8200 vector behaviour through the i950 PROFIBUS module and the L_ICIP library.

Key Advantages

• Proven vector control for steady torque at low speed.
• 1.8 x rated torque overload for 60 s handles tough starts.
• Built-in brake chopper cuts panel space and wiring.
• Flexible bus options cover most factory networks.
• Clear migration path to the i950 keeps your design future-proof.

Installation Guide

• Mount the drive vertically on a flat panel. Keep the IP20 enclosure inside a cabinet.
• Reserve free space above and below for airflow. Heat rises, so never block the top.
• Use the single-phase 180…264 V AC supply for this 230 V class unit.
• Add an external EMC filter. This C2xx variant has no integrated filter.
• Tighten power terminals to the torque in the Lenze manual.
• Connect the brake resistor to the built-in chopper when you need fast stops.
• Keep motor cables short and screened. This lowers noise on the RS232/485 bus.
• Set the switching frequency to 8 kHz as a safe default. Raise it only when motor noise matters.

Commissioning and Maintenance

• Enter motor data from the nameplate. The drive then tunes itself to the motor.
• Use the Lenze keypad or a PC tool for fast parameter setup.
• Check the 1.8 x torque overload setting for your load cycle.
• Clean the heatsink every few months in dusty rooms. Dust blocks cooling.
• Inspect fan and terminal screws at each service visit.
• Log DC bus values to spot a weak brake resistor early.
• Keep spare plug-in modules on hand. Swap time is only minutes.

Compatibility Notes

• Works with standard 4-pole asynchronous motors in the 230 V class.
• Fits Lenze system bus networks out of the box.
• Adds PROFIBUS DP, CANopen, DeviceNet, INTERBUS or AS-Interface through plug-in modules.
• Two control interface slots allow mixed setups on one drive.
• No drop-in same-order-code replacement exists for newer drive lines.
• Official migration path: i950 with PROFIBUS module and L_ICIP library. Lenze AKB articles 321231 and 316137 cover this path for 8200 vector, 9300, 8400 and 9400.
• DC supply is not allowed on E82EV251/371 units. Check your unit code first.

Certifications and Compliance

Expert Review

The E82EV251K2C200 is a solid pick for small conveyors, pumps and fans that run on 230 V single phase. Vector control keeps torque steady at low speed. The built-in brake chopper saves panel space. The main limit is the missing EMC filter. Budget for an external filter and cabinet space. Buyers who plan a new line should compare the i950 path before locking in this legacy model.

Manager’s Insight

This drive sells well as a like-for-like spare. Plants with 8200 vector machines keep one on the shelf. Order the exact code E82EV251K2C200 to avoid wiring changes. For new builds, we advise the i950 with a PROFIBUS module. It copies 8200 vector behaviour and stays supported longer.

Best Fit Applications

• Small conveyors and packaging lines
• Pumps and fans with light variable loads
• Textile and woodworking machines
• Retrofit and spare-part service for 8200 vector panels
• Machines that need quick braking with a resistor

FAQ

• Does this unit include an EMC filter?
  No. The C2xx variant ships without one. Add an external filter to meet EMC limits.
• Can I use it on a 3-phase supply?
  This model is for single-phase 180…264 V AC. Check the 3-phase versions for three-phase mains.
• What overload can it take?
  It delivers 1.8 x rated torque for 60 s. Size the motor with that in mind.
• Is a brake resistor built in?
  The brake transistor is built in. The resistor itself is external.
• Can I feed it from a DC bus?
  Yes on most units at 260…370 V DC. The E82EV251 and E82EV371 units are excluded.
• How do I move to a newer drive?
  Lenze confirms the i950 emulates 8200 vector behaviour via the i950 PROFIBUS module and L_ICIP library.
• How fast do you ship?
  Orders leave in 12-24 hours by FedEx, UPS or DHL.
• What is the warranty?
  12 months from delivery.
• Experience tip: my motor hums at low speed.
  Lower the switching frequency to 4 kHz and re-run motor identification. Hum often drops.
• Experience tip: trips on start.
  Check the overload setting against the 2.5 A for 60 s limit. A cold motor also needs more ramp time.
• Buying guide: spare or new build?
  Match the full code for spares. For new builds, price the i950 kit with its bus module first.
• Buying guide: which bus module?
  Pick the module your PLC already uses. One module type per network keeps spares simple.
