---

1. Basic Product Information

---

2. Product Introduction

The 20G11ND2P1JA0NNNNN is a compact industrial AC variable frequency drive belonging to the PowerFlex 755 series.

It is designed for three-phase AC motor control and is particularly suitable for machinery requiring adjustable motor speed, controlled acceleration and deceleration, network communication, motor protection, diagnostic information, and flexible control functions.

The drive has a 480 VAC three-phase input and a 2.1 A output-current rating. Its compact Frame 2 construction makes it suitable for applications where the available cabinet space is limited but advanced drive functionality is still required.

Unlike a basic standalone frequency converter, this drive is intended to operate as part of a larger industrial automation system. The embedded EtherNet/IP communication capability allows the drive to exchange control and diagnostic information with an industrial controller.

The drive also incorporates an internal dynamic-braking transistor, which makes it particularly useful for applications where controlled deceleration is required.

---

The product belongs to the PowerFlex 755 series.

The PowerFlex 755 platform is designed for applications where flexibility, networking, advanced motor control, diagnostics and optional expansion are important.

The series covers a broad range of industrial motor-control requirements, from relatively small motors through much larger industrial machines.

---

4. Model Number Interpretation

The complete catalog number is:

20G11ND2P1JA0NNNNN

The catalog number contains several configuration identifiers.

The 2P1 portion is especially important because it identifies the small current class of the drive.

The drive is therefore intended for relatively small motors, while still providing the more advanced control and communication capabilities associated with the PowerFlex 755 platform.

---

5. Main Electrical Parameters

---

6. Motor Capacity

The drive has a nominal 1 HP normal-duty capacity.

For a small industrial motor, this provides enough capacity for applications such as compact conveyors, small pumps, small fans, blowers, packaging machinery, feeders and other low-power rotating equipment.

The actual motor should not be selected from horsepower alone.

The motor nameplate current should be checked carefully because the motor’s actual operating current is the most useful value when matching the motor to the drive.

---

7. Physical Dimensions

The approximate physical dimensions are:

16.7 in high × 5.3 in wide × 8.35 in deep

Converted to metric units, this is approximately:

424 mm × 135 mm × 212 mm

The dimensions above represent the approximate drive body envelope.

For cabinet design, additional space should be allowed for power cables, control wiring, communication wiring, airflow and maintenance access.

---

8. Product Weight

The approximate product weight is:

7.1 kg

A commonly listed shipping/product reference weight is approximately 15.5 lb, which corresponds to about 7.1 kg.

The actual shipment weight may be higher depending on packaging, documentation and accessories.

---

9. Enclosure and Protection

The drive is an IP20/IP00, NEMA/UL Open Type product.

This means it is generally intended to be installed inside a suitable electrical cabinet or enclosure.

It should not normally be treated as a weatherproof or washdown-rated standalone device.

A suitable cabinet should provide protection against:

• Water
• Excessive dust
• Conductive contamination
• Chemical contamination
• Mechanical damage
• Foreign objects
• Excessive humidity

The final protection level of the complete system depends on the enclosure used by the installer.

---

10. Cooling System

The product uses forced-air cooling.

During operation, the power semiconductor components generate heat. The internal cooling system moves air through the drive to remove this heat.

For reliable operation, cabinet design should consider:

• Ambient temperature
• Cabinet temperature
• Air circulation
• Ventilation
• Drive loading
• Heat generated by neighboring components
• Filter cleanliness
• Installation clearance

For installations containing several drives, the combined heat dissipation of all equipment should be considered.

---

11. Embedded EtherNet/IP

One of the strongest features of the 20G11ND2P1JA0NNNNN is its embedded EtherNet/IP capability.

This allows the drive to be integrated into an industrial automation network.

Instead of using separate hardwired connections for every basic function, a controller can exchange information with the drive over the industrial Ethernet network.

Typical information includes:

This makes the drive particularly suitable for automated machinery.

---

12. Dynamic Braking

The product includes an internal dynamic-braking transistor.

Dynamic braking is useful when the driven machine has rotating inertia and needs controlled deceleration.

During deceleration, the motor can return energy to the drive’s DC bus. If the DC-bus voltage rises sufficiently, a braking circuit can direct the excess energy to a properly selected braking resistor.

This can provide:

• Faster stopping
• Controlled deceleration
• Better handling of high-inertia loads
• Improved machine cycle control
• Reduced dependence on mechanical braking

Typical applications include:

• Small conveyors
• Feed mechanisms
• Packaging equipment
• Rotating machinery
• Small material-handling equipment
• Machines requiring frequent stopping

The braking resistor must be selected according to the actual braking energy and duty cycle.

---

13. EMC Filtering

The J configuration indicates the filtered/CM-jumper-installed arrangement.

EMC filtering is useful for controlling high-frequency electrical noise associated with variable frequency drive operation.

Good EMC performance also depends on installation practices.

Important factors include:

• Motor cable construction
• Cable shielding
• Grounding
• Cable length
• Cable routing
• Cabinet grounding
• Separation between control and power cables
• Proper termination

The drive’s internal filtering should therefore be considered one part of the overall EMC design.

---

14. Motor Control
