Quick Reference: Power, Voltage and IP Rating
| Parameter | Lenze E82EV302-4C | Lenze E94P050T4NEM |
|---|---|---|
| Drive series | 8200 vector frequency inverter | 9400 HighLine servo drive |
| Supply voltage | 3 AC 400 V class, 50/60 Hz | 3 AC 400 V, 50/60 Hz |
| Voltage tolerance | Typically ±10%, verify nameplate | Typically ±10%, verify nameplate |
| Rated output power | 3.0 kW class | 5.0 kW class |
| Output current | 6.0 A class, verify nameplate | Check full nameplate value |
| IP rating | IP20 | IP20 |
| Motor type | Three-phase asynchronous motor | Servo / synchronous motor |
| Mounting | Inside control cabinet | Inside control cabinet |
| Cooling | Internal fan / heat sink | Forced-air cooling |
These two drives share the same 400 V supply class but serve different power levels and different motor control tasks.
What This Check Confirms
Before installation or replacement, verify three values.
First, voltage. Both drives require a 3-phase 400 V supply. A 230 V single-phase supply will not work.
Second, power. The E82EV302-4C is a 3.0 kW class drive. The E94P050T4NEM is a 5.0 kW class drive. They are not interchangeable for the same motor.
Third, IP rating. Both are IP20. They must be installed inside a protected control cabinet.
If you are using both drives in one panel, the power and voltage check is simple. The load check is different. The E82EV302-4C runs a standard three-phase motor. The E94P050T4NEM typically controls a servo motor with feedback.
Model Code Reading
Lenze model codes carry the main electrical data.
Lenze E82EV302-4C:
– E82 = 8200 vector series
– 302 = 3.0 kW power class
– 4 = 400 V voltage class
– C = version suffix
Lenze E94P050T4NEM:
– E94 = 9400 servo series
– 050 = 5.0 kW power class
– T = three-phase supply
– 4 = 400 V voltage class
– NEM = option / version suffix
Always match the complete nameplate code, not just the short model. Options such as fieldbus module, keypad, brake control, or encoder input change the full order number.
Voltage Check Procedure
Step 1. Read the nameplate on the drive side panel.
Step 2. Confirm input voltage marking: 3 AC 400 V.
Step 3. Check the connected supply. The incoming voltage must be within the drive tolerance.
Step 4. If the supply is 380 V, 400 V, or 415 V, standard industrial systems usually can run. If the supply is 230 V single phase, stop and source the correct drive version.
Step 5. Check the motor and drive voltage class match. A 400 V drive needs a 400 V motor winding configuration.
For multi-drive panels, do not add kW only. Add the actual input currents and size fuses, breakers, and wiring separately for each drive.
Power Check Procedure
Power class is not the only selection factor. Output current is more important.
For the E82EV302-4C, check the motor full load current against the drive output current. If the motor current exceeds the drive rating, the drive will trip on overcurrent or overheat.
For the E94P050T4NEM, the same rule applies. A 5.0 kW class drive cannot automatically run every 5.0 kW motor. The servo motor current, speed range, and dynamic load matter.
If you replace an E82EV302-4C with an E94P050T4NEM, do not assume it is a direct upgrade. The E94P050T4NEM is designed for servo loops. It is not a standard VFD replacement for a simple induction motor conveyor drive.
IP Rating and Installation Limits
Both drives are IP20.
IP20 means:
– Protection against solid objects larger than 12.5 mm
– No protection against water or moisture
These drives are not field-mountable. They belong in a control cabinet.
Recommended installation:
– Cabinet protection: IP54 or higher in normal factory environments
– Ambient temperature: typically 0 °C to 40 °C for continuous rated load
– Derating: reduce output current above 40 °C
– Altitude: derate above 1000 m
– Clearance: 100 mm above and below the drive, 50 mm side clearance
In dusty, humid, or corrosive areas, use cabinet air filtration or sealed cooling.
Pairing E82EV302-4C and E94P050T4NEM
One common machine application: the E82EV302-4C runs the main conveyor or feed roll, while the E94P050T4NEM runs a servo axis for positioning or tension control.
That combination works well because both drives use the same 400 V panel supply. But panel design must cover:
– Separate line protection for each drive
– Separate fuses or MCBs sized to each input current
– Inrush current when energizing both drives
– Heat load from two drives in one cabinet
– Cable spacing between power and encoder cables
Do not share a single motor between these two drives without proper switching and interlock.
Replacement and Buying Checklist
When confirming a replacement, prepare this data:
– Complete drive model code from the nameplate
– Serial number
– Firmware version, if visible
– Mounting dimensions and connector arrangement
– Type of motor connected
– Required option cards: fieldbus, encoder, brake, keypad
For the E82EV302-4C, older 8200 vector units may have different firmware and keypad versions. For the E94P050T4NEM, check the exact option suffix and whether safety functions such as STO are required.
Do not buy on power class alone. A 5.0 kW E94P050T4NEM and a 3.0 kW E82EV302-4C are both 400 V IP20 drives, but they have different control behavior, motor compatibility, and commissioning requirements.
Common Mistakes
| Mistake | Correct action |
|---|---|
| Installing IP20 drives outside a cabinet | Use at least IP54 cabinet |
| Matching kW but ignoring current | Compare output current to motor FLC |
| Supplying 230 V single phase | Use correct 400 V 3-phase supply |
| Replacing E94P050T4NEM with a standard VFD | Verify servo loop and encoder requirement |
| Mixing E82EV302-4C and E94P050T4NEM motor functions | Keep VFD duty and servo duty separate |
FAQ
Can both drives run on the same 400 V supply?
Yes. Both are 3 AC 400 V class. Use separate protection and cable sizing.
What is the IP rating of the E82EV302-4C and E94P050T4NEM?
Both are IP20. Install inside a protected control cabinet.
What is the difference in power rating?
E82EV302-4C is 3.0 kW class. E94P050T4NEM is 5.0 kW class.
Can I replace E82EV302-4C with E94P050T4NEM?
Not directly. The E94P050T4NEM is a servo drive. Confirm motor type, encoder, and control loop first.
Why does the nameplate show a longer code than E82EV302-4C?
Lenze adds suffixes for options such as fieldbus, keypad, and brake control. Always match the full nameplate order code.
Where can I verify exact Lenze drive specifications?
Send the complete nameplate photo and serial number to a qualified industrial automation supplier. The drive model can be checked against Lenze order data.
