What Makes This Drive Stand Out

Unlike basic VFDs, the PowerFlex 70 platform supports three distinct control modes — Volts per Hertz, Sensorless Vector, and Vector Control with FORCE Technology. That last option is particularly valuable: it delivers precise torque and speed regulation across a wide range of loads, from simple fans and pumps to more demanding applications like conveyors and extruders.

The drive's Enhanced Control variant provides advanced functionality without requiring external feedback devices. Combined with the built-in Brake IGBT, it handles deceleration more efficiently, reducing the need for additional hardware in many setups.

Enclosure & Mounting

Rated IP20 / NEMA Type 1, the 20AD3P4A0AYNNNC0 is built for panel mounting inside a control cabinet. The blank plate (no HIM installed) keeps the front profile clean, and a Human Interface Module can be added separately if on-drive programming is needed later.

Frame A dimensions make this a space-efficient option when panel real estate is at a premium.

Communication & Network Integration

This drive supports a broad range of industrial communication protocols out of the box. Optional internal communication modules enable fast data exchange over EtherNet/IP, ControlNet, DeviceNet, MODBUS, and PROFIBUS — making it straightforward to integrate into both legacy systems and modern PLC architectures.

Software tools such as DriveExplorer™ and DriveTools™ SP are fully compatible for remote programming, parameter monitoring, and fault diagnostics.

Typical Applications

The PowerFlex 70 series covers a wide range of use cases. The 20AD3P4A0AYNNNC0, with its 2 HP rating and 480V input, is well suited for:

Conveyor belt systems
Pump and fan control
Packaging and material handling equipment
HVAC motor control
Light-duty machine tool applications

Frequently Asked Questions

Q: What is the output current rating of the 20AD3P4A0AYNNNC0?

A: It provides 3.4A continuous output, with short-term ratings of 4.5A for up to 1 minute and 6A for up to 3 seconds.

Q: Does this drive include a Human Interface Module (HIM)?

A: No. The 20AD3P4A0AYNNNC0 ships with a blank plate in place of a HIM. If you require on-drive display and programming capability, a compatible HIM module can be sourced and installed separately.

Q: What control modes are available on this drive?

A: Three modes are supported — Volts/Hertz for simple speed control, Sensorless Vector for improved torque at lower speeds, and Vector Control with FORCE Technology for high-performance applications requiring precise regulation.

Q: Can this drive communicate with a PLC over a network?

A: Yes. With optional communication modules, the drive supports EtherNet/IP, ControlNet, DeviceNet, MODBUS, and PROFIBUS — covering most common industrial network environments.

Q: What is the enclosure rating, and is it suitable for outdoor installation?

A: The drive is rated IP20 / NEMA Type 1, which is designed for indoor panel-mount installation only. For outdoor or washdown environments, a higher-rated enclosure or an enclosed drive variant would be required.

Q: Does the drive include a brake resistor?

A: The brake IGBT is installed internally, but the drive does not include a drive-mounted brake resistor. An external resistor can be connected if the application requires dynamic braking.

Q: What is the horsepower range of the PowerFlex 70 series overall?

A: The PowerFlex 70 family covers 0.5 to 25 HP at 240V AC, 0.5 to 50 HP at 480V AC, and 0.5 to 50 HP at 600V AC — making this specific 2 HP model one of the smaller units in the lineup.

Q: Is this a new or refurbished unit?

A: The unit listed on our site is new and in current stock, ready for immediate dispatch.
