Overview Manuals Specifications Safety & Compliance Compatibility & Interoperability Applications

Features:

  • Extreme Overtorque for Heavy Loads
  • Integrated Safety (Power Removal)
  • Flexible High-Frequency Output
The Schneider Electric ATV71HU40N4Z delivers a massive 220% transient overtorque for 2 seconds. This feature ensures that your conveyor or hoist can break away stuck loads or overcome sudden peak demands without tripping, reducing unexpected downtime in critical lifting operations.

Eliminate the need for external contactors with the built-in Power Removal function of the Schneider Electric ATV71HU40N4Z. This safety input prevents the drive from generating torque to the motor, conforming to ISO 13849-1 standards, allowing for safe machine cleaning and maintenance directly from the drive terminal.

Achieve near-silent motor operation by increasing the switching frequency up to 16 kHz on the Schneider Electric ATV71HU40N4Z. This is ideal for office-environment machinery or textile applications where audible noise is a concern, though users must apply a current derating factor as per the technical manual.

The ATV71HU40N4Z Schneider Electric Variable Speed Drive may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Schneider Electric ATV71HU40N4Z represents the pinnacle of the Altivar 71 range, engineered specifically for asynchronous and synchronous motors in high-power applications. Unlike standard drives, this model provides a massive 220% transient overtorque capability, ensuring that heavy loads are moved safely and efficiently even in the harshest industrial environments. Its compact design (155mm width) allows for easy integration into existing motor control centers.

Equipped with advanced sensorless flux vector control (SFVC), the Schneider Electric ATV71HU40N4Z offers precise speed and torque regulation without the need for an encoder. The drive supports a wide output frequency range of 0.1 to 599 Hz and features a configurable switching frequency up to 16 kHz (with derating). Whether you are operating a crane or an extruder, this drive maintains +/- 0.01% speed accuracy in closed-loop mode, guaranteeing smooth operation and reduced mechanical stress on your equipment.

Safety and connectivity are at the forefront of the Schneider Electric ATV71HU40N4Z. It comes standard with integrated "Power Removal" (Safe Torque Off) terminals, allowing for safe machine maintenance without disconnecting the main power supply. Furthermore, with native Modbus and CANopen protocols, this drive easily communicates with your PLC or building management system, reducing wiring costs and improving diagnostic capabilities.

Technical notes
The Schneider Electric ATV71HU40N4Z is unique in its class for offering a built-in EMC filter and Class 1 safety functions (Power Removal) in a standard IP20 housing. Users should note that while the drive supports a 16 kHz switching frequency for silent motor operation, a current derating is required above 4 kHz. For optimal longevity, installation requires vertical mounting with specific clearance to maintain the ambient temperature range of -10°C to 50°C without derating.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Does the Schneider Electric ATV71HU40N4Z require an external filter to pass CE compliance?
No. This specific "N4Z" variant includes an integrated EMC filter. The Schneider Electric ATV71HU40N4Z meets EN 55011 Class A, standard for industrial environments, saving you the cost of an external filter and the labor to install it.
How does the Schneider Electric ATV71HU40N4Z help with diagnosing a motor failure?
It features a dedicated PTC probe input (via L16). If your motor overheats, the Schneider Electric ATV71HU40N4Z reads the resistance change instantly and shuts down with a specific thermal fault code, saving your motor windings. It also provides a red LED indicator for immediate visual drive status.
Can the Schneider Electric ATV71HU40N4Z run in a dusty environment without an expensive cabinet?
Yes, partially. The base unit is rated IP20 (top), but the documentation confirms that by removing the protective blanking cover and installing it in a specific metal enclosure (Type B/C mounting), you can achieve effective protection against dust and dripping water without requiring a full IP54 drive replacement.
What specific problem does the Schneider Electric ATV71HU40N4Z solve in real-world applications?
The main issue it resolves is motor stalling under sudden heavy loads. Unlike standard drives that trip on overcurrent, the Schneider Electric ATV71HU40N4Z maintains control with 220% torque, ensuring that lifting equipment or mixers don't stop mid-cycle when encountering a material jam.
