Frequently Asked Questions

Does the E94ASHE0134 support standard Ethernet communication protocols?

Yes, the 9400-Series supports Ethernet-based communication through the use of specific communication modules. You should verify the specific module requirement based on your network architecture (e.g., Profinet vs. EtherCAT).

Can this drive be used for safety-critical applications?

The 9400-Series is designed to support integrated safety functions. However, the specific safety level depends on the hardware configuration and the safety modules installed. Always ensure that safety systems are certified to your local regulatory requirements.

How is the drive configured and parameterized?

The drive is configured using the Lenze engineering software suite. This allows for parameterization, commissioning, and detailed diagnostic monitoring of motion profiles via a PC connection to the drive's communication port.

Engineering Integration and Operational Protocols

• Shielding Requirements: Due to the high-speed switching frequencies used in 9400-Series servo drives, proper EMC shielding is vital. Use only shielded motor cables with a 360-degree connection to the PE ground at the drive entrance to mitigate high-frequency interference.
• Cabinet Cooling: With a rated output of 5.5 kW, ensure that the control cabinet is sized for adequate airflow. Mount the drive vertically with at least 100 mm of clearance above and below the unit to allow for unimpeded heat dissipation from the integrated heatsinks.
• DC Bus Sharing: The 9400-Series supports DC bus sharing for multi-axis configurations. When implementing this, ensure that the common DC bus is properly fused and that total regenerative energy is managed by a centralized braking resistor or a feed-in/regenerative power supply module.
• Safety Commissioning: Always perform a dry-run test without the motor load coupled to the mechanical system during the initial commissioning phase to verify motion direction and limit switch logic.
