Description
Lenze E84AVSCE7514SXO
Product Introduction
Small motor drives are often replaced on a like-for-like basis, but the voltage class and current rating still need to match the motor and cabinet design. The Lenze E84AVSCE7514SXO belongs to the 8400 StateLine C inverter family and is identified as a 0.75 kW drive with a 2.4 A rated current in the 7514 configuration. Lenze documentation places the E84AVSCE7514 family in the 400/500 V three-phase class.
The 8400 StateLine C platform is intended for variable-speed operation of AC motors, with compact panel-mounted construction for machine and industrial automation applications. The exact SXO suffix should be retained when purchasing a replacement; similar E84AVSCE7514 variants can differ in ordering configuration. This is a legacy drive family, so compatibility should be checked against the motor data, control wiring, parameter set, and installed braking or EMC arrangement rather than by kW rating alone.

Application Scenarios & Pain Points
1. Small industrial motor drives
At 0.75 kW, this drive fits the small-motor segment of the 8400 StateLine C family. Typical machine applications include pumps, fans, conveyors, small process auxiliaries, and other continuously variable-speed loads.

2. Machine automation
The compact 8400 StateLine C architecture was intended for integration into machine control cabinets. Its role is generally to receive a speed or control command from the machine controller and regulate the connected AC motor.
3. Legacy machine replacement
The E84AVSCE7514SXO is particularly relevant when maintaining an installed Lenze 8400 system. Keeping the same family and rating can simplify replacement, but the original parameter set should still be recovered before commissioning.
4. 400/500 V motor systems
The 7514 designation is important. Lenze lists the E84AVSCE7514 as a 0.75 kW, 2.4 A model in the 400/500 V class. The 7512 version is a different configuration, listed at 0.75 kW and 4.0 A. Those two should not be treated as interchangeable simply because both carry the 7514/7512 family size.

The Lenze family documentation distinguishes the StateLine and HighLine variants, while the 7512 and 7514 versions also have different electrical ratings. Confirm the exact application before substituting one for another.
Engineer’s Guide — Field Pitfalls to Avoid
1. Do not confuse E84AVSCE7514 with E84AVSCE7512
This is one of the easiest procurement errors. Both are 0.75 kW drives, but the available specifications identify the 7514 at 2.4 A and the 7512 at 4.0 A. The electrical configuration is therefore not identical.
2. Match the complete suffix
Your supplied number is E84AVSCE7514SXO. Public documentation commonly shortens the family designation to E84AVSCE7514, while equipment records use the longer SXO form. Keep the complete nameplate number in the purchasing record rather than dropping the suffix.
3. Do not size the replacement from motor kW alone
A 0.75 kW motor does not automatically determine the correct drive. Check motor rated current, supply voltage, overload requirement, braking requirements, acceleration/deceleration profile, and control method. The drive’s 2.4 A rating needs to be evaluated against the actual motor and duty.
4. Check the control wiring before removal
For an existing machine, document the digital inputs, analog reference, relay outputs, enable circuit, and any external braking or fault-reset wiring. A replacement drive can have the correct power rating and still fail to operate correctly because the machine-side control interface was wired or parameterized differently.
5. Preserve the parameter set
Do not assume that the factory defaults will reproduce the original machine behavior. Motor nameplate data, minimum/maximum frequency, acceleration/deceleration ramps, current limits, control source, fault behavior, and any application-specific parameters should be recorded before replacing a functioning unit.
6. Verify EMC and installation requirements
The 8400 StateLine C documentation includes specific installation and EMC requirements. Cabinet grounding, cable routing, motor cable length, shielding, and any external EMC filter arrangement should be checked rather than copied from a different drive size. The family is associated with external filter arrangements in Lenze documentation.
FAQ
What is Lenze ?
It is a Lenze 8400 StateLine C frequency inverter rated at 0.75 kW and 2.4 A, in the 400/500 V three-phase class. The complete supplied designation includes the SXO suffix.
What motor size is this Lenze drive designed for?
The family is rated for 0.75 kW motor applications. Actual motor suitability should still be checked against rated current and operating duty rather than using horsepower/kW as the only selection criterion.
What is the difference between and E84AVSCE7512?
Both are 0.75 kW members of the 8400 StateLine C family, but the documented ratings differ: , while E84AVSCE7512 is 4.0 A. They should therefore be treated as different electrical configurations.
Is a servo drive?
It is more accurately classified as a frequency inverter / AC motor drive in the Lenze 8400 StateLine C family. It is intended for variable-speed control of AC motors rather than being identified as a dedicated servo amplifier.
What voltage does the 7514 version use?
The is listed in the 400/500 V three-phase configuration. Lenze documentation shows the 7514 model within the 400 V-class E84AVSCE group.
Can replace another 0.75 kW Lenze drive?
Not automatically. The other drive may use a different voltage class, current rating, control architecture, or feature set. In particular, compare the complete order code and distinguish the 7512, 7514, StateLine C, and HighLine C variants before approving a substitution.
What should be checked before purchasing a replacement?
Confirm the complete nameplate, input voltage, motor rated current, firmware/revision where applicable, control wiring, parameter backup, EMC/filter arrangement, braking requirements, and mechanical installation dimensions. If the available unit is used or refurbished, verify the actual hardware condition and functional test status rather than relying on the listing description.
