Technical Specifications

Specifications should be checked against the drive nameplate and applicable technical documentation before installation. Actual operating ratings depend on supply voltage, duty classification, motor characteristics, and installation conditions.

Function and Working Principle

The PowerFlex 700S drive controls the electrical power supplied to a three-phase AC motor. It converts incoming electrical power into a variable-frequency output and adjusts motor operation according to programmed parameters and external control commands.

Its Phase II control architecture is intended for applications requiring more advanced motor-control functions than basic fixed-speed operation.

1. Variable-Frequency Motor Control

An AC motor’s operating speed is closely related to the frequency of its electrical supply. By adjusting output frequency, the drive allows the motor to operate at different speeds according to the requirements of the production process.

For example, a material-handling system may need to accelerate gradually when starting, maintain a stable operating speed during production, and slow down when equipment upstream or downstream changes state.

Variable-frequency control makes these operating transitions possible without relying entirely on mechanical speed-control equipment.

2. Advanced Phase II Control

The 20DB104A0EYNANANE uses the Phase II control configuration of the PowerFlex 700S family. This architecture provides advanced drive-control capabilities for applications where motor performance and system coordination are important.

The drive can be configured according to the connected motor and the requirements of the machine. Correct motor data, parameter settings, and commissioning procedures are necessary to achieve the intended performance.

The control architecture should not be confused with a communication network option. This particular catalog configuration does not include an internal communication module.

3. Incremental Encoder Feedback

The specified configuration includes a standard incremental encoder arrangement. Encoder feedback provides information about motor rotation and speed, allowing the control system to use feedback signals when the application requires more accurate motor regulation.

In an appropriate closed-loop configuration, the drive can compare feedback information with the commanded operating condition and adjust motor control accordingly.

The encoder, wiring, signal type, and feedback settings must be compatible with the drive configuration. A replacement with a different feedback option may require changes to the existing control arrangement.

4. Acceleration and Deceleration Control

The drive supports independently adjustable acceleration and deceleration settings. These parameters determine how quickly the motor moves between operating speeds.

Gradual acceleration can reduce mechanical shock during startup. Controlled deceleration can help coordinate stopping sequences and reduce stress on connected equipment.

The correct settings depend on motor characteristics, load inertia, process timing, and braking requirements. Applications with frequent or rapid deceleration require particular attention to regenerated energy and braking-circuit capacity.

5. Braking Circuit Operation

The specified model includes a braking IGBT but does not include a drive-mounted braking resistor.

The braking IGBT is a switching component used in a braking circuit. It does not independently dissipate regenerated energy. Where the application requires dynamic braking, an appropriate external resistor or another engineered braking solution may be necessary.

The braking arrangement must be selected according to the motor, load inertia, stopping frequency, and manufacturer requirements.

6. EMC Management

The drive includes an EMC filter and common-mode choke. These components help manage electromagnetic interference associated with variable-frequency motor operation.

Correct grounding, cable shielding, conductor routing, and cabinet layout remain essential. The presence of an EMC filter does not eliminate the need for proper installation practices.

Role in Industrial Control Systems

The 20DB104A0EYNANANE can operate as a central motor-control component within a larger industrial automation system. It receives operating commands and speed references while controlling the electrical power delivered to the motor.

PLC-Based Control

A programmable logic controller can coordinate the drive with sensors, actuators, safety interlocks, and other production equipment.

Depending on the system design, the PLC may issue run commands, provide speed references, coordinate acceleration and deceleration, and respond to drive status signals.

Because this model does not include an internal communication module, engineers must verify the available control interfaces and any additional hardware needed for the intended PLC integration.

HMI and Operator Monitoring

A human-machine interface can provide operators with information about motor operation, production status, alarms, and process conditions.

The specified drive configuration has no installed HIM. Local operation, parameter access, and commissioning therefore need to be planned using a compatible interface and the appropriate configuration procedures.

In many installations, the HMI communicates with the PLC, while the PLC manages drive commands and operating sequences.

Encoder-Based Motor Feedback

The standard incremental encoder configuration can support applications that require motor-speed feedback.

The encoder provides information that may be used by the drive’s control system to regulate motor operation. Correct encoder installation and parameter configuration are important for stable feedback performance.

Coordination with Industrial Machinery

The drive can form part of a coordinated motor-control system involving conveyors, pumps, fans, mixers, or other equipment. The PLC and drive work together to align motor operation with production requirements.

This approach allows motor speed and operating sequences to be adjusted as process conditions change.

Industrial Applications

The PowerFlex 700S series is intended for industrial motor-control applications where adjustable speed and advanced control functionality are required. The 20DB104A0EYNANANE’s 40 HP normal-duty and 30 HP heavy-duty ratings make it suitable for appropriately matched motor loads.

1. Material Handling Systems

Material-handling equipment often requires controlled acceleration, stable running speed, and predictable stopping behavior.

The drive can regulate compatible conveyor motors and support coordination between different sections of a production or transportation line. Encoder feedback may be useful where motor-speed regulation is important to the process.

2. Industrial Pumps

Industrial pumping systems may operate under changing flow or pressure requirements. A variable frequency drive can adjust motor speed to match process demand in suitable applications.

The drive must be selected according to pump characteristics, motor current, fluid conditions, and the required operating range.

3. Fans and Blowers

Large ventilation and air-handling systems may require adjustable airflow according to production conditions or environmental requirements.

Variable-speed control can provide operational flexibility and may reduce energy consumption when the fan operates below its maximum speed for extended periods.

4. Mixers and Processing Equipment

Mixers and process machines often experience changing mechanical loads. A suitable drive can regulate motor operation and support controlled acceleration and deceleration.

The required torque, starting conditions, and operating duty should be assessed before selecting the drive.

5. Manufacturing and Production Machinery

The PowerFlex 700S can be used in manufacturing equipment where motor control is closely coordinated with automated production sequences.

Applications may include material-processing machinery, machine auxiliaries, industrial transport systems, and other equipment requiring controlled AC motor operation.

The final selection should be based on the motor nameplate, load profile, feedback requirements, and available control interfaces.

Installation and System Integration

Correct installation is necessary for safe operation and reliable motor control. The 20DB104A0EYNANANE should be installed by qualified personnel familiar with industrial drive systems and applicable electrical standards.

1. Verify the Input Power Supply

Confirm that the incoming supply matches the drive’s 240 V AC three-phase rating and the applicable 208 V configuration.

Check supply frequency, phase arrangement, protective-device requirements, and grounding before connecting the drive.

The 104 A output rating and the normal-duty and heavy-duty power ratings should be considered when selecting the motor. A drive should not be selected solely according to the motor’s horsepower.

2. Confirm Mounting Space

The supplied dimensions are 339.9 × 644.5 × 275.4 mm, with a listed weight of 37.19 kg.

Allow additional space for cooling airflow, power and control wiring, maintenance access, and safe installation. Confirm the manufacturer’s dimensional drawing before preparing the cabinet or mounting structure.

The IP20 / NEMA Type 1 configuration is intended for protected installation conditions. It does not provide unrestricted protection against water, conductive dust, or corrosive contaminants.

3. Power Wiring and Grounding

Power wiring, motor wiring, control wiring, and grounding must follow the applicable installation instructions.

Use conductors and protective devices rated for the electrical characteristics of the system. Keep control and feedback cables appropriately separated from power cables to reduce interference.

Before installation or maintenance, isolate the power supply and follow the required lockout and verification procedures.

4. Encoder Installation

Since this configuration includes a standard incremental encoder arrangement, verify the encoder type, supply requirements, signal connections, and cable specifications.

Incorrect feedback wiring or incompatible encoder signals can affect motor-control performance and may prevent the drive from operating as intended.

Check the encoder configuration and related parameters during commissioning.

5. Braking System Design

The drive includes a braking IGBT but does not include an internal drive-mounted braking resistor.

For applications involving rapid stopping, frequent deceleration, or high-inertia loads, calculate the braking requirements and determine whether an external braking resistor is necessary.

The resistor must be compatible with the drive and selected according to the manufacturer’s electrical and thermal requirements. Do not assume that the braking IGBT alone provides complete braking-energy dissipation.

6. Parameter Configuration and Commissioning

Configure the motor nameplate data, control mode, speed references, feedback settings, acceleration and deceleration times, and protection parameters.

Test the complete system under controlled conditions. Verify motor direction, speed response, feedback operation, stopping behavior, interlocks, and fault handling.

Record the final parameter settings for future maintenance and replacement work.

Compatible System Components

The 20DB104A0EYNANANE is generally installed as part of a larger industrial motor-control system. The following components may be used depending on the application design.

These components are examples of equipment used in a complete system. They are not necessarily included with the drive.

Alternative Models and Replacement Considerations

The PowerFlex 700S 20D family has been discontinued. Replacement planning should therefore consider both the original electrical ratings and the control configuration.

Before choosing a replacement, compare:

• Input voltage and phase configuration.
• Continuous output current.
• Normal-duty and heavy-duty ratings.
• Motor voltage and current requirements.
• Phase II control functionality.
• Incremental encoder feedback compatibility.
• Braking IGBT and resistor arrangements.
• EMC filter and common-mode choke configuration.
• PLC control and communication requirements.
• Physical dimensions and cabinet cooling requirements.
• Parameter migration and commissioning requirements.

A replacement with a similar horsepower rating is not automatically interchangeable. Changes in control architecture, encoder feedback, communication hardware, and terminal assignments may require modifications to the existing system.
