Product details

Product Overview

Model E82EV751K4C040 is a Lenze 8200 vector frequency inverter. It is a panel-mounted E-design unit.
It drives a 0.75 kW four-pole asynchronous motor. Rated output current is 2.4 A at 8 kHz.
This variant includes an integrated EMC filter and Safe Torque Off (STO). The STO function supports safer machine stops.
Control modes cover V/f linear and quadratic, vector control, and sensorless torque control. One drive fits many load types.
The unit has no onboard fieldbus. You add fieldbus or extra I/O with plug-in option modules.
Lenze lists the 8200 vector as a legacy product. The official migration path is the i950 series.
There is no drop-in same-order-code replacement. Plan the migration before you standardise spares.
This drive suits retrofits, spare-part stock, and small machines that already use the 8200 vector family.

Interference immunity: the integrated EMC filter supports compliant installation in industrial cabinets.

Installation Guide

Mount the drive vertically in a cabinet. Keep the heatsink airflow clear.
Use push-through mounting when you need IP41 protection.
Wire supply to the 3/PE terminals. Check 320 to 550 V AC before power-up.
Connect the motor to U, V, W. Match the motor nameplate to the 0.75 kW rating.
Wire control signals to X3. Shield analog cables and bond the shield at one end.
Keep motor cables short. Separate power and signal routes inside the cabinet.
For STO wiring, follow the Lenze terminal assignment for the x4x variant. Test the stop function before production.
Derate output above +40 °C by 2.5 % per °C. Do not exceed +55 °C.

Commissioning and Maintenance

Set motor data first: voltage, current, frequency, and speed.
Choose V/f for simple fans and pumps. Choose vector control for higher starting torque.
Set the switching frequency to 8 kHz for a balance of noise and loss. Raise it only when motor noise matters.
Use the noise-optimised setting when acoustic noise is a concern.
Record parameter sets after commissioning. Keep a copy for every machine.
Clean the heatsink on a fixed schedule. Check fan operation and terminal torque.
Service is straightforward: the drive uses plug-in option modules and standard control terminals.
Order spare option modules early. The family is legacy, so lead times can vary.

Compatibility Notes

Works with standard four-pole three-phase asynchronous motors rated 0.75 kW.
Fieldbus and extra I/O come from 8200 vector plug-in modules. Examples include E82ZAFSC010 and E82ZAFAC010.
The drive has no integrated fieldbus or Ethernet port. Plan the network option at order time.
For new projects, Lenze points to the i950 series. The i950 emulates 8200 vector behaviour with the i950 PROFIBUS module and the L_ICIP library.
There is no drop-in same-order-code replacement. Check wiring and parameter mapping before you swap.
Legacy status is OFFICIAL_VERIFIED as of October 2026.

Certifications and Compliance

Protection rating IP20 per EN 60529; IP41 with push-through mounting.
Climatic class 3K3 per EN 50178.
Integrated EMC filter supports filtered installation in industrial environments.
Safe Torque Off supports machine safety concepts in the x4x variant. Confirm your safety level with a qualified engineer.
Always check local rules for electrical installation and machine safety.

Expert Review

The 8200 vector earned its place in small machines. It is simple to wire and easy to understand.
The 0.75 kW size covers conveyors, fans, and small pumps with little effort.
The STO variant adds real value for machine builders who need a safe stop without extra hardware.
Watch the legacy status. Buy spares now, and plan the i950 path for new builds.
The 2.4 A rating and 1.8 x overload cover most light-duty starts without oversizing.

Manager’s Insight

Keep this unit for retrofit and spare-part demand. That is where it pays back fastest.
Do not design new machines around the 8200 vector. Use the i950 and reuse the parameter logic.
Stock the E82ZAFSC010 I/O module with the drive. Missing modules delay startups.
Set a clear derating rule above +40 °C. Heat is the main cause of early failure.
Document every parameter set. Repeat service calls drop when records are complete.

Best Fit: Equipment and Applications

Conveyors and material handling lines with light loads.
Fans and pumps using V/f quadratic control for energy savings.
Small packaging machines that need vector control and a safe stop.
Machine retrofits that already use the 8200 vector family.
Spare-part stock for plants that run legacy Lenze drives.
Not ideal for new fieldbus-heavy designs. Choose the i950 for those projects.

FAQ

Does this drive include a fieldbus port?
No. It has no onboard fieldbus. You add one with a plug-in option module.
Can I replace an old 8200 vector with this exact model?
Yes, if the old unit carries the same order code. Lenze confirms there is no generic drop-in replacement across the family.
What motor should I pair with it?
A four-pole three-phase asynchronous motor rated 0.75 kW. Match the nameplate current to 2.4 A.
How much overload can it handle?
3.6 A for 60 s, or 1.8 x rated torque for 60 s when the ratings match.
Is the STO function ready to use?
The x4x variant includes STO. Wire it per the Lenze terminal plan and test it before production.
What happens above +40 °C?
Derate by 2.5 % per °C. The maximum operating temperature is +55 °C.
Can I mount it through the cabinet wall?
Yes. Push-through thermally separated mounting raises protection to IP41.
From experience, what fails first?
Heat and dirty heatsinks. Clean the cooling path on a fixed schedule and keep cabinet filters fresh.
What should I check before power-up?
Supply voltage, motor wiring, shield bonding, and STO wiring. Then run a no-load test.
Is a manual available?
Yes. Lenze keeps 8200 vector documentation online. Keep a copy with the machine file.
Why is the series marked legacy?
Lenze has moved to newer drive generations. The 8200 vector stays supported through documentation and the i950 migration path.
Do you ship fast?
Yes. Orders ship within 12 to 24 hours. We use FedEx, UPS, and DHL.

Buying Guide

Confirm the order code first. The x4x position marks the STO variant.
Check your motor current. Stay at or below 2.4 A continuous.
Decide on fieldbus now. Add the right plug-in module with the drive order.
Measure cabinet temperature. Plan derating above +40 °C.
For new machines, compare the i950 before you commit to a legacy platform.
Buy one spare per critical machine. Legacy stock shrinks over time.
Ask us for a parameter checklist with your order. We include it on request.
