E94AMHE0044 Lenze Servo Axis Module CANopen DC-Bus Cabinet Drive

E94AMHE0044 Lenze 9400 HighLine Multi Drive Axis Module

The E94AMHE0044 is a Lenze axis module in the Servo Drives 9400 HighLine Multi Drive series. It mounts in a DC-bus cabinet. It drives a 1.5 kW 4-pole asynchronous motor in the 400 V class. Rated output current is 5 A at 4 kHz. Peak current is 7.5 A. Short-term current reaches 16 A. The overload factor is 4. CANopen is built in. Two slots add function modules. This module suits compact multi-axis machines that need more power than the 0.75 kW class.

Expert Review

The E94AMHE0044 adds real power in the same slim body. It doubles the motor rating of the 0.75 kW class. The 16 A short-term current covers tough starts. The 4x overload factor keeps peaks safe. Built-in CANopen saves wiring time. Two slots keep room for growth. Plan for derating above +45 °C. Cabinet airflow is the main design point. This is a strong choice for mid-size asynchronous motor control.

Manager’s Insight

This unit moves fast in multi-axis retrofit work. Buyers like the Lenze build and the active 9400 lifecycle. Keep spare E94AYC modules in stock. Offer the E94AZCUS adapter as an add-on.
