The Schleicher ATV320U22N4C is widely applied in industrial automation systems where precise motor speed regulation is essential for process efficiency. In manufacturing lines, material handling systems, and complex machinery, stable motor performance directly impacts productivity and system reliability. By supporting a voltage range of 380 to 500 V and heavy-duty motor loads up to 2.2 kW, the drive provides adaptable performance for various industrial applications. Its compact structure allows integration into control panels where space efficiency is critical. This makes it suitable for both new installations and system upgrades.
From a functional perspective, the Schleicher ATV320U22N4C delivers accurate motor control through defined output current and frequency regulation. The drive ensures smooth operation with a switching frequency of 4 kHz and controlled output characteristics. It also supports dynamic load conditions through transient overtorque capability, helping maintain process stability during sudden changes. The inclusion of multiple discrete inputs and outputs enables flexible control system design. These features allow seamless integration into automated production environments.
In industrial use cases, the Schleicher ATV320U22N4C supports applications requiring reliable speed control, controlled braking, and electrical noise reduction. DC injection braking provides precise stopping control, improving machine safety and positioning accuracy. The built-in EMC filter helps maintain stable operation in electrically noisy environments common in industrial facilities. Wide temperature tolerance ensures reliable performance in both harsh and standard conditions. Overall, the drive enhances operational efficiency, system flexibility, and long-term equipment reliability.
The ATV320U22N4C Schleicher Variable Speed Drive may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Heavy-Duty Reference Continuous Output Current: Provides up to 5.5 A of continuous output current at a default switching frequency of 4 kHz, fully utilizing the potential of heavy-duty motors.
- Transient High-Current Extremely Fast Peak Response: Supports providing up to 8.3 A of overload transient current within 60 seconds, relying on onboard high-speed computing units to eliminate stall caused by sudden external disturbances.
- High-Protection Chemical Anti-Corrosion Coating: The circuit board surface is coated with a hard anti-corrosion paint, achieving Class 3C3 tolerance as specified in IEC 60721-3-3, allowing the equipment to operate without an airtight cabinet in high-sulfur, heavy chemical salt spray environments.
- Seamless Modular Network Expansion: Natively provides Modbus RTU and CANopen interfaces, and supports horizontal expansion to EtherCAT, Profinet, EtherNet/IP, and DeviceNet industrial buses via plug-in cards.
- Extreme Grid Distortion Tolerance and Current Limiting: Supports robust operation in harsh voltage grids ranging from 380V to 500V (variation range -15% to +10%), and can withstand expected short-circuit current (Isc) surges up to 5 kA.
- Overvoltage Grid Phase Break Instantaneous Degradation Protection: Hardware components integrate fast-response input phase break detection, activating emergency degradation logic in the event of a sudden phase failure to prevent permanent breakdown of bus capacitors.
- High-Density, Compact, Spacing-Free Installation: Optimized heat dissipation design allows for side-by-side, zero-gap, tight mounting without the need for a ventilation cover, significantly reducing the physical space required by the control cabinet.
- High Mechanical Stress Vibration-Resistant Self-Isolating Structure: The overall frame meets vibration stress specifications of 10 m/s² (13Hz to 200Hz range), specifically designed to withstand the intense transient vibrations caused by heavy-duty construction machinery operation.
- High-precision multi-material quantitative packaging machinery: Deployed in fully automated packaging and boxing production lines, utilizing the high static speed accuracy and closed-loop torque of the frequency converter at low speeds to prevent overfilling due to excessive inertia during material weighing.
- High-load unbalanced dehydration in industrial washing machines: Integrated into the frequency converter control of heavy-duty commercial washing equipment, utilizing 170% to 200% transient over-torque output to forcibly overcome the huge eccentric reaction force caused by uneven distribution of clothes in the early stages of high-speed dehydration.
- Multi-segment speed control for metal material cutting and forming: Applied to automated metal sawing machines or drilling centers, multiple operating speeds are preset through the module's built-in SoMove configuration software, enabling adaptive switching of cutting rates for materials of different hardness.
- Automatic opening and closing control of safety protection doors: In large gantry machining centers or mechanical partition doors, the inverter's native safety door locking (Guard Door Locking - GDL) function ensures that the electromagnetic lock is released to safely open the door only after the motor is completely disconnected from power and the spindle has completely stopped, protecting operator safety.
