LENZE E94AMHE0244 Servo Drive Servo Control in stock

The Lenze E94AMHE0244 is a specific model of a sophisticated servo drive. Let's break down everything you need to know about it.

The E94AMHE0244 is part of Lenze's 9400 HighLine series of servo inverters. This is a top-tier, high-performance servo drive designed for demanding motion control applications.

E94AMHE: Indicates the series (9400) and the product line (HighLine).

0244: This is the crucial part of the model number, indicating the drive's power rating.

02: Typically refers to a 200V class power supply (common single-phase/three-phase 200-240V AC).

44: Indicates the output current rating. In this case, 44 Amps RMS.

In simple terms, this is a powerful and precise "brain" for a servo motor, capable of controlling its position, speed, and torque with high accuracy and dynamics.

Key Features and Characteristics

High Performance: Designed for applications requiring very fast response times, high dynamics (rapid acceleration/deceleration), and precise positioning.

High Overload Capability: Servo drives are built to handle short-term peak currents much higher than their continuous rating. This allows the connected motor to deliver high torque for brief moments (e.g., to overcome inertia during startup or for a pressing operation).

Integrated Safety Functions (Safe Torque Off - STO): Like most modern drives, it includes integrated safety features to disable the power output to the motor, which is crucial for protecting personnel during maintenance or in case of a fault.

Fieldbus Connectivity: It supports various industrial communication protocols (like CANopen, PROFIBUS, PROFINET, EtherCAT, etc.) via plug-in option modules. This allows it to communicate seamlessly with a higher-level PLC (Programmable Logic Controller).

Advanced Control Functions: It goes beyond simple motion control, offering features like:

Gearing: Electronically linking the motion of one axis to another.

Camming: Creating a complex relationship between master and slave positions.

Position Control: Executing complex moves from an internal sequence.

Typical Applications

This drive is used in high-power, high-precision automation machinery. Common examples include:

Packaging Machines: High-speed filling, labeling, and palletizing systems.

Printing and Converting Machines: Where precise registration and web tension control are critical.

Material Handling: Robotic arms, automated guided vehicles (AGVs), and pick-and-place systems.

Machine Tools: CNC milling machines, lathes, etc.

Large-scale Automation: Any application where a standard inverter or a smaller servo drive is not powerful enough.
