6SE7023-4EP70-Z Siemens | 34A Motion Control Frequency Inverter

Siemens 6SE7023-4EP70-Z | SIMOVERT MASTERDRIVES Motion Control 15kW Drive

The Siemens 6SE7023-4EP70-Z is a high-performance frequency converter from the esteemed SIMOVERT MASTERDRIVES family, specifically engineered for advanced motion control. This 15 kW drive unit provides the precise torque regulation and dynamic response necessary for complex industrial automation tasks. Because it utilizes field-oriented vector control technology, it maintains absolute speed stability even under fluctuating load conditions. The "Z" designation indicates a factory-customized configuration, often including specialized software or hardware options for unique machine requirements. Moreover, the unit delivers a robust 34 Amp nominal current, making it a powerhouse for medium-scale industrial motors. This drive remains a vital asset for facilities that prioritize the proven reliability of Siemens legacy infrastructure.

Maintaining productivity in high-speed manufacturing environments requires drive hardware that can operate continuously without thermal degradation. This converter features a compact, cabinet-mountable design with an integrated cooling system to ensure long-term electronic health. Furthermore, the 6SE7023-4EP70-Z offers comprehensive protection against earth faults, short circuits, and thermal overloads to safeguard your motor investments. Although Siemens has moved toward the SINAMICS series for new installations, this MASTERDRIVES unit is essential for maintaining legacy lines. Therefore, sourcing this original Siemens component is the most effective way to ensure your machinery continues to meet production quotas.

Technical Specifications

Frequently Asked Questions (FAQ)

What does the "Z" suffix represent in this specific model?

The "Z" signifies that the unit was built with specific factory-installed options or customized firmware for a particular application.

Can this drive be used as a direct replacement for an older 6SE7023-4EP70 without the Z?

In most cases yes, but you must verify that the internal option boards match your existing system configuration exactly.

Does this unit support EnDat or resolver feedback for servo motors?

The base unit requires specific encoder or resolver interface cards to be installed in the option slots for feedback.

How do I handle an "Overtemperature" fault on this 15 kW module?

You should immediately inspect the internal cooling fan for dust accumulation and ensure the cabinet ventilation meets Siemens' airflow standards.
