Installation Guide

• Mount the module in a DC-bus cabinet. Use the 507 installation backplane.
• Connect the DC-bus supply within 260 V to 775 V range. Check polarity.
• Wire the motor according to the 3 kW / 8.8 A rating. Use shielded cables.
• Insert extension modules into the two available slots. Tighten screws firmly.
• Connect CANopen via the built-in port. Set node ID and baud rate.
• For diagnostics, plug the USB adapter (E94AZCUS) into the diagnostic interface.
• Respect IP20 protection. Install in a clean, dry control cabinet.
• Ensure adequate ventilation. Observe derating above 45 °C or 1000 m altitude.

Commissioning & Maintenance

• Use Lenze engineering software for parameter setup. Auto-tune the motor.
• Check all connections before power-on. Verify DC-bus voltage.

Expert Review

The E94AMHE0074 stands out for its 3× overload capacity and flexible extension slots. Field engineers appreciate the built-in CANopen port, which cuts wiring time. The wide DC-bus range (260-775 V) suits both 400 V and 480 V systems. Cooling design keeps the 190 W power loss manageable. However, users must remember the 2.5 %/°C derating above 45 °C. The IP20 rating limits use to clean cabinets. Overall, this module delivers reliable performance for multi-axis servo applications.

Manager’s Insight

We see strong demand for Lenze 9400 HighLine modules in packaging and printing machinery. The E94AMHE0074 balances power (3 kW) and compact size (90 mm width). Clients often pair it with safety modules in the second slot. Lead times stay short because we stock this item. Remember: order the USB adapter separately for diagnostics. For high-altitude sites, derate current by 5 % per 1000 m above sea level. This module reduces cabinet space by 30 % compared to older designs.

Best Fit Devices & Applications

• Packaging machines: high cycle rates need 3× overload.
• Printing presses: precise speed control with CANopen.
• Material handling: conveyors and hoists with 4-pole motors.
• Textile machinery: multi-axis synchronization.
• Woodworking equipment: compact cabinet integration.
• Robotic cells: auxiliary axis control.

FAQ

Q: Can I use this module with a 480 V DC-bus?
A: Yes. The input range is 260 V to 775 V DC. 480 V DC falls comfortably inside. Just observe the +0 % tolerance.

Q: What is the maximum short-term current?
A: The module delivers 21 A for short periods. This supports acceleration peaks. Overload factor is 3×.

Q: Do I need an external CANopen card?
A: No. CANopen is built into the HighLine board. Use the on-board port. For other protocols, add an E94AYC… module.

Q: How do I connect a PC for setup?
A: Use the USB diagnostic adapter E94AZCUS. Plug it into the diagnostic interface. The adapter is not included.

Q: What happens above 45 °C?
A: Derate the rated output current by 2.5 % per °C. At 55 °C, you lose 25 % current. Plan cooling accordingly.

Q: Is this module compatible with a 9300 series drive?
A: No. The 9400 HighLine Multi Drive uses different bus mechanics. Do not mix series.

Q: What is the warranty period?
A: Every unit carries a 12-month warranty. Covers manufacturing defects. Shipping damage is excluded.

Q: How fast do you ship?
A: Orders leave our warehouse within 12-24 hours. We use FedEx, UPS, or DHL. You get tracking.

Q: Can I use this module at 3000 m altitude?
A: Yes, but derate current by 5 % per 1000 m above 1000 m. At 3000 m, derate by 10 %. Ensure extra cooling.

Q: Where can I get technical support?
A: Email sales@powergearx.com or message +86 18030005825 on WhatsApp. Response within one business day.
