ATV930U22N4 Variable Speed Drive 2.2kW 400-480V Brake Chopper IP21

The ATV930U22N4 is a compact three-phase variable speed drive designed for precise speed, torque and process control in industrial machinery. It provides a rated output of 2.2 kW under normal-duty conditions or 1.5 kW under heavy-duty conditions.

Compared with higher-power drive models, this unit combines a narrower 144 mm enclosure with a lighter 4.5 kg construction, making it suitable for control cabinets where installation space is limited. Its 5.6 A normal-duty output is well suited to pumps, fans and other variable-torque loads, while the 4 A heavy-duty rating supports machinery requiring greater short-term overload capability.

An integrated brake chopper enables connection to a correctly selected external braking resistor when faster deceleration or controlled stopping is required. Built-in Ethernet and serial communication interfaces simplify connection to programmable controllers, monitoring systems and industrial networks.

Key Features

• 2.2 kW output for normal-duty applications
• 1.5 kW rating for heavy-duty machinery
• 5.6 A continuous normal-duty output current
• 4 A continuous heavy-duty output current
• Compact 144 mm wide wall-mounted enclosure
• Integrated brake chopper for dynamic braking applications
• Adjustable output frequency from 0.1 to 599 Hz
• Integrated EMC filter for reduced conducted interference
• Built-in EtherNet/IP, Modbus TCP and Modbus serial communication
• Safe Torque Off function rated to SIL 3
• Control support for asynchronous and synchronous motors
• IP21 enclosure for protected cabinet installations

Normal Duty and Heavy Duty Difference

Normal-duty mode is intended for applications with moderate overload requirements. Heavy-duty mode provides greater short-term overload capacity but requires the connected motor power to be limited to 1.5 kW.

Communication Interfaces

The drive includes the following communication protocols as standard:

• EtherNet/IP
• Modbus TCP
• Modbus serial through an RS-485 interface

Two RJ45 connectors are provided for Ethernet communication, together with one RJ45 connector for serial communication. Other industrial network protocols require a compatible optional communication module and should not be listed as built-in features.

Typical Applications

• Centrifugal pumps
• Ventilation and extraction fans
• Small conveyor systems
• Mixers and agitators
• Packaging machinery
• Material handling equipment
• Water treatment equipment
• Process control machinery
• Industrial utility systems
• Compact automation cabinets

Installation and Selection Notes

Install the drive vertically to maintain the correct cooling airflow. Recommended clearance should be maintained above and below the enclosure, particularly when multiple drives are installed in the same cabinet.

Select the operating mode according to the motor rating and load characteristics. A 2.2 kW motor can be used in normal-duty operation, while heavy-duty applications should use a motor rated at no more than 1.5 kW.

The integrated brake chopper does not replace the external braking resistor. When dynamic braking is required, resistor resistance, power rating and duty cycle must be calculated according to the motor inertia and stopping frequency.

Verify the supply voltage, motor current, grounding method, enclosure ventilation and protective devices before commissioning.

Frequently Asked Questions

1. What is the rated motor power of ATV930U22N4?

The rated motor power is 2.2 kW in normal-duty operation and 1.5 kW in heavy-duty operation.

2. What input power supply does this drive require?

It requires a three-phase 380–480 V AC power supply with a frequency of 50–60 Hz.

3. What is the continuous output current?

The continuous output current is 5.6 A in normal-duty mode and 4 A in heavy-duty mode at a 4 kHz switching frequency.

4. Why is the heavy-duty power rating lower?

Heavy-duty operation provides greater overload capacity. To maintain safe thermal performance, the connected motor power is reduced from 2.2 kW to 1.5 kW.

5. Does this drive include a brake chopper?

Yes. An integrated brake chopper is provided for applications requiring dynamic braking.

6. Is a braking resistor included?

No. A compatible external braking resistor must be selected separately according to the required stopping time and braking cycle.

7. Which communication protocols are built in?

EtherNet/IP, Modbus TCP and Modbus serial communication are built in.

8. Can it control permanent magnet motors?

Yes. It supports asynchronous motors, permanent magnet synchronous motors and synchronous reluctance motors when correctly configured.

9. What are the drive dimensions?

The enclosure measures approximately 144 mm wide, 350 mm high and 206 mm deep.

10. Can it be installed outdoors?

The standard enclosure is rated IP21 and is primarily intended for indoor cabinet installation. Outdoor use requires a properly rated external enclosure.

11. What is the maximum output frequency?

The adjustable output frequency range is 0.1–599 Hz. The permitted motor operating frequency must still follow the motor manufacturer’s limits.

12. Does it support a safety shutdown function?

Yes. It includes a Safe Torque Off function rated to SIL 3 when installed and configured according to the applicable safety requirements.
