Industry Applications
Its 5.5 kW output and 0.1…599 Hz frequency range allow precise speed control for asynchronous motors in open or closed loop. The integrated CANopen and Modbus interfaces simplify integration into existing automation networks, reducing commissioning time.
Installation & Setup Guidance
Mount the drive vertically within ±10 degrees to ensure proper cooling. Use shielded cable up to 50 m or unshielded up to 100 m for motor connections. The IP20 rating requires installation in a clean, dry enclosure. Connect power to terminals L1/R, L2/S, L3/T and motor to U/T1, V/T2, W/T3. Tighten power terminals to 3 N.m. Configure control via the Modbus or CANopen port using the built-in RJ45 connectors.
Maintenance & Reliability
Inspect the drive periodically for dust buildup on the heat sink. Operating ambient temperature should remain between -10 and 50°C to avoid derating. The drive includes thermal protection for both the motor and drive itself, reducing unplanned downtime. With an IP20 enclosure, ensure the environment is free from excessive moisture and conductive dust.
Compatibility & Integration
The ATV71HU55N4Z supports both Modbus and CANopen protocols via RJ45 and SUB-D 9 connectors. It is compatible with a wide range of option cards including Profibus DP, EtherNet/IP, and DeviceNet. This flexibility allows seamless integration into new or existing control systems.
Selection Guide & Purchasing Advice
When selecting a variable speed drive, verify voltage, power, and communication requirements. The ATV71HU55N4Z is a solid choice for 5.5 kW three-phase motors.
