Installation Guide

• Mount the module on the 507 installation backplane inside the cabinet.
• Keep the IP20 enclosure closed during operation.
• Connect the DC bus within 260 V to 775 V. Check polarity first.
• Use shielded motor cables. Keep them short and well grounded.
• Route CANopen wiring away from motor power cables.
• Respect clearance above and below the module for airflow.
• Derate current 2.5 % per °C when cabinet air exceeds +45 °C.
• Derate current 5 % per 1000 m above 1000 m site altitude.
• Tighten terminals to the torque stated in the Lenze manual.
• Verify PE bonding before you apply DC-bus power.

Commissioning and Maintenance

• Use the USB diagnostic port with the E94AZCUS adapter for setup.
• Lenze engineering tools load parameters quickly over this port.
• Set motor data and switching frequency before the first run.
• Run an autotune cycle to match the 4-pole motor.
• Check CANopen node ID and baud rate twice before power-up.
• Monitor DC-bus current and heatsink temperature during trials.
• Clean air filters on a fixed schedule. Dust raises internal temperature.
• Inspect fan and cable shields every six months.
• Replace worn fans early. Heat is the main lifetime factor.
• Store spare modules in a dry place within -25 °C to +60 °C.

FAQ

• Q: Can I use this module with a synchronous servo motor?
• A: It is specified for 4-pole asynchronous motors in the 400 V class. Check motor data before you buy.
• Q: What is the maximum DC-bus voltage?
• A: The range is 260 V to 775 V DC. Stay inside it at all times.
• Q: How do I connect a laptop for setup?
• A: Use the USB diagnostic port with the E94AZCUS adapter. The Lenze tool finds the drive quickly.
• Q: Does it support EtherCAT or PROFINET out of the box?
• A: No. CANopen is on board. Add an E94AYC module for other protocols.
• Q: What happens above +45 °C cabinet temperature?
• A: Derate rated output current by 2.5 % per °C. Ignoring this shortens module life.
• Q: How fast do you ship?
• A: We dispatch in 12 to 24 hours on business days via FedEx, UPS or DHL.
• Q: Is a warranty included?
• A: Yes, 12 months cover material and workmanship.
• Q: From experience, what fails first on these modules?
• A: Cooling fans and dirty filters. Clean filters monthly and replace fans early.
• Q: Any tip before I swap a module between machines?
• A: Match firmware and parameter sets first. Mismatches cause most startup faults.
• Q: How do I choose the right variant?
• A: Match rated current to motor current, then confirm DC-bus voltage and needed protocol slots.
• Q: Can I parallel two modules on one motor?
• A: No. Use one module per motor and size it for the load.

Buying Guide

• Start with motor current, not just kW rating.
• Confirm the DC-bus voltage in your existing cabinet.
• List the protocols you need today and next year.
• Count free E94AYC slots in your design.
• Check cabinet air temperature and plan derating.
• Check site altitude for highland installations.
• Order the E94AZCUS adapter if you lack one.
• Ask us for a firmware check before shipping. It avoids surprises.
