Product Description

Lenze E84AVTCE3714VX0 — 8400 TopLine C Frequency Inverter, 0.37 kW

When an application demands more than simple speed control — when positioning accuracy, dynamic torque response, or synchronized multi-axis motion is part of the brief — the choice of inverter matters. The E84AVTCE3714VX0 sits at the top of the Lenze 8400 family as a TopLine C variant, bringing servo-quality drive behavior to a compact 0.37 kW unit built for three-phase 400/500V installation.

TopLine C: The Top of the 8400 Family

The Lenze 8400 series spans four tiers — BaseLine, StateLine, HighLine, and TopLine — each offering progressively more capability. The TopLine C is the highest-performing variant, and the feature set that separates it from the others comes into focus immediately:

An integrated resolver input supports the standard feedback interface of Lenze servo motors without requiring an additional encoder feedback card. This is significant — it means servo-grade closed-loop speed and torque control is available natively, without third-party adapters or extra hardware spend. Beyond the resolver, the TopLine accepts multiple encoder types including incremental encoders and absolute position measurement systems, expanding the range of motors and feedback devices it can work with.

The drive also implements electrical shaft and electronic gearbox functions internally. These replace what would otherwise require separate motion controllers — two or more axes can be synchronized to run at precise speed ratios, or one axis can follow another's position profile, all within the inverter's own processor without external coordination logic.

0–1000 Hz Output Frequency — Why It Matters

Most general-purpose inverters top out at 300–600 Hz output frequency. The 8400 TopLine C reaches 1000 Hz, which opens the door to applications that standard drives simply cannot address: high-speed spindles, special-purpose motors with high pole pair counts, and precision positioning applications where rapid frequency response directly translates to control bandwidth.

For a 0.37 kW unit, this output range means the drive is equally at home running a small servo motor at very high speed or providing precise low-speed torque control at the other end of the spectrum.

CANopen On Board — Optional Fieldbus Expansion

Every 8400 TopLine C includes CANopen as a standard on-board communication interface, requiring no additional communication module for systems built on CAN-based networks. When the machine architecture calls for a different fieldbus, optional communication modules add EtherCAT, EtherNet/IP, POWERLINK, PROFIBUS, or PROFINET support — and the mechanical footprint of the base unit doesn't change regardless of which module is fitted.

This modular approach to communication is one of the practical strengths of the 8400 platform: the same base drive can be configured for virtually any industrial network environment in use today.

Installation and Cabinet Design

The E84AVTCE3714VX0 is an installation-mount unit designed for control cabinet integration, with an IP20 open-style enclosure. At the 0.37 kW power rating, the physical dimensions are compact — the smallest frame size in the 8400 range — and the drive supports side-by-side installation without air gaps between units at this size, allowing dense multi-drive cabinet layouts.

DC bus connection between adjacent drives is also supported, which enables braking energy from decelerating axes to be fed directly to accelerating axes on the same bus, reducing total energy draw and minimizing the need for braking resistors in systems with multiple coordinated drives.

Where This Drive Gets Used

The combination of servo control quality, integrated resolver input, 1000 Hz output capability, and built-in axis synchronization functions makes the TopLine C a natural fit for:

Handling and pick-and-place systems requiring precise positioning
Travelling drives and gantry axes in intralogistics and warehouse systems
Hoist and lifting drives demanding dynamic torque control
Rotary indexing and assembly machines with multi-axis synchronization
Packaging machinery requiring coordinated electronic shafts or gearbox functions
High-speed spindle drives and precision machining applications

Frequently Asked Questions

Q: What is the difference between the E84AVTCE3714VX0 and other E84AVTCE3714 variants like SX0 or SB0?

A: All E84AVTCE3714 variants share the same 0.37 kW, 400/500V, TopLine C power stage. The suffix characters change specific options. The VX0 uses a standard installation mount design without safety engineering under standard ambient conditions, with output frequency capability up to 1000 Hz. The SX0 is similarly a standard unit without safety engineering. The SB0 adds the STO (Safe Torque Off) safety function. The "V" position in the VX0 suffix relates to the specific version identifier in Lenze's ordering system — always verify the exact suffix when replacing an existing unit to ensure a like-for-like match.

Q: Does the E84AVTCE3714VX0 require a separate encoder card for servo motor control?

A: No. The 8400 TopLine C includes an integrated resolver input as standard, which directly supports Lenze servo motors with resolver feedback without any additional hardware. For motors using incremental or absolute encoders, the multiple encoder inputs on the TopLine C terminal strip handle those signal types natively as well.

Q: What fieldbus communication does this drive support?

A: CANopen is integrated on-board as standard. Additional fieldbuses — EtherCAT, EtherNet/IP, POWERLINK, PROFIBUS, and PROFINET — are available via optional plug-in communication modules that attach to the front of the drive.

Q: Can multiple E84AVTCE3714VX0 units be mounted side by side in a cabinet?

A: Yes. At the 0.37 kW size, adjacent installation without air gaps is supported, allowing compact multi-drive arrangements. The drives also support DC bus coupling between adjacent units, enabling energy recovery from decelerating drives to power accelerating drives on the same bus.

Q: What is the maximum output frequency?

A: The 8400 TopLine C reaches a maximum output frequency of 1000 Hz, compared to 300–600 Hz typical of standard frequency inverters. This extended range supports high-speed spindle and specialized motor applications in addition to standard variable-speed drives.

Q: How does the electronic gearbox function work?

A: The integrated electronic gearbox allows this drive's motor to follow the speed of a master axis at a defined ratio — without any external motion controller. The ratio is set via parameters, and the drive handles the synchronization internally. This replaces mechanical gearboxes or external PLC-based ratio control in many applications.

Q: What programming tools are used with this drive?

A: The 8400 TopLine C is configured and commissioned using Lenze's »EASY Starter« software tool, which provides guided parameter setup, diagnostics, and live monitoring. The drive also has an integrated keypad for basic parameter access directly on the device.

Q: What does "Brand New 1pc" mean for this listing?

A: The unit is factory-new, genuine Lenze manufacture, unused and in original packaging. One piece is available in current inventory for immediate dispatch — not refurbished, not tested-used, not cosmetically repackaged surplus.
