The Schneider Electric Altivar Machine ATV320 ATV320U22N4C variable speed drive is designed for controlling asynchronous and synchronous motors in machinery and automation systems. It offers a rated power of 2.2 kW in Heavy Duty service, operates with a three-phase 380 to 500 V AC supply, and features a compact format especially suited for integration into electrical cabinets and machines where advanced motor control is required.
The ATV320U22N4C reference provides a continuous output current of 5.5 A at 4 kHz and supports a transient current of up to 8.3 A for 60 seconds. It includes an EMC C2 filter, Modbus and CANopen communications, multiple safety functions, and different motor control profiles, offering a complete solution for industrial applications and complex machinery.
The Schneider Electric ATV320U22N4C is sized for 2.2 kW motors, equivalent to 3 HP, in Heavy Duty service. Its 380 to 500 V AC supply range allows it to be used on common industrial three-phase networks.
The Altivar Machine ATV320 is designed to control both asynchronous motors and synchronous motors. It offers different control profiles that make it possible to adapt drive behavior to the characteristics of the motor and the application.
For asynchronous motors, it includes, among other options:
For synchronous motors, it provides sensorless vector control, making it easier to use with different motor technologies within the conditions established by Schneider Electric.
The drive provides a wide frequency regulation range, from 0.1 to 599 Hz. The nominal switching frequency is 4 kHz and can be adjusted between 2 and 16 kHz.
When using high switching frequencies, it may be necessary to apply current derating according to the manufacturer's instructions.
The Schneider Electric ATV320 incorporates different functional safety functions directly in the drive, making it easier to integrate into machines with advanced protection requirements.
These functions must be integrated in accordance with the machine safety architecture and Schneider Electric's specific instructions.
The ATV320U22N4C includes Modbus and CANopen communications as standard via an RJ45 connection, making it easy to integrate with PLCs, controllers, and other automation components.
In addition, optional communication modules allow it to be incorporated into different industrial networks:
The drive offers different configurable inputs and outputs to adapt to the machine control system.
It features 6 configurable digital inputs plus the STO safety input. One of the inputs can be configured as a pulse input and another supports use with a PTC probe depending on the configuration.
The ATV320 includes an adjustable PID regulator, allowing control of processes that require maintaining a variable around a setpoint. This function expands its use in machinery and automatic regulation applications.
It also features different acceleration and deceleration ramps, automatic adaptation of the deceleration ramp, and stopping by DC injection.
The drive supports the use of an external braking resistor for applications that require energy dissipation during demanding decelerations. With a braking resistor, it can provide a braking torque of up to approximately 170% for 60 seconds under the conditions indicated by Schneider Electric.
The ATV320U22N4C reference includes a factory-installed Class C2 EMC filter. The drive meets the corresponding electromagnetic compatibility requirements when installation, grounding, wiring, and accessories are carried out in accordance with the manufacturer's recommendations.
The Altivar Machine ATV320 includes different monitoring systems designed to protect both the drive and the motor against abnormal conditions.
These internal functions must be complemented by the external electrical protections required by the installation.
The C in the reference identifies the compact format version. This configuration has dimensions of 140 mm wide, 184 mm high, and 158 mm deep, allowing the drive to be housed in automation cabinets without requiring a particularly bulky format.
The Schneider Electric ATV320U22N4C offers an IP20 protection rating in accordance with EN/IEC 61800-5-1, so it is primarily intended for installation inside a suitable electrical enclosure or cabinet.
Cooling is provided by an integrated fan, with an air flow of approximately 37.7 m³/h.
The drive can operate between -10 and 50 °C without derating. Between 50 and 60 °C, it can continue operating with the current derating specified by Schneider Electric.
The Schneider Electric Altivar Machine ATV320U22N4C 2.2 kW is a compact variable speed drive designed for machinery that requires advanced motor control and broad integration capability. Its 5.5 A output, three-phase 380-500 V supply, synchronous and asynchronous motor control, Modbus and CANopen communications, EMC C2 filter, and STO, SS1, SLS, SMS, and GDL safety functions make it suitable for a wide range of industrial automation applications.
