PowerFlex®700L Liquid-cooled AC drives are responsive, high performance, regenerative industrial drives for installations requiring a compact footprint. The PowerFlex 700L drive offers two versions of control: either the PowerFlex 700 Vector Control or the PowerFlex 700S Phase II Control. This provides the PowerFlex 700L drive with exceptional and proven performance as well as the same interface, communications capabilities and programming tools of the air-cooled drives. The many features allow you to easily configure the drive for most application needs. Ratings presently available include:•268...960 Hp (200...715 kW) at 400V AC•300...1150 Hp (224...860 kW) at 480V AC•465...870 Hp (345...650 kW) at 600V AC•475...881 Hp (355...657 kW) at 690V ACKey Features/BenefitsSpace Saving FeaturesThe PowerFlex 700L AC drive features a patented liquid-cooled heatsink design to transfer over 80% of the drive heat loss to the liquid coolant, resulting in the best drive power-to-size ratio in the market. The integral active converter and line filter translate to a fully regenerative drive that's over 60% smaller than typical air-cooled drives.Integrated Line Regenerative Braking For Precise Control and Energy Savings•The Liquid-cooled AC drive features regenerative braking which is ideal for precise, high-response speed and position control, continuous holdback, rapid deceleration and stopping of high inertia loads. Instead of wasting energy with resistor braking technology, regenerative braking actually puts the energy back into the system to be used by other equipment.•Regenerative braking eliminates the need for large resistor banks. These resistors banks can create a lot of heat and must frequently be cleaned.Improved Power Quality with Regenerative Rectifier•Compact and cost-effective means to achieve compliance with CE and IEEE 519 harmonic limits.•Actively controls power factor regardless of motor speed which reduces input line currents and minimizes the size of upstream devices.•Input Voltage Boost•Integrated active converter and line-side filter allow ‘input voltage boost’ to protect your system from power disturbances.•Maintains consistent system performance in the event of power dips or other power quality issues.•Provides full 480V AC to the motor even when operating on 380V AC power lines.Frame 2Frame 3B (shown with enclosure doors open)

Rockwell Automation Publication 20L-TD001E-EN-P - March 20203PowerFlex 700L Liquid-cooled AC DrivesFlexible Control Platforms•Designed for applications with requirements ranging from the simplest speed control to the most demanding torque control, the PowerFlex 700L drive is available with either PowerFlex 700 Vector Control or PowerFlex 700S Control.•Outstanding open or closed loop speed regulation for applications ranging from fans and pumps to precise winder control.•Excellent torque production and tight torque regulation for demanding applications like extruders, web process, and test stands.•Fast update times of torque inputs are suitable for high performance applications.•All of this flexibility is possible through multiple control modes: V/Hz control, Sensorless Vector, Vector Control with FORCE™ Technology, and Permanent Magnet Control (700S control only).•Safe Torque Off Option (available with the PowerFlex 700S Control option), the first offering available within the DriveGuard™ series of safety solutions, prevents a drive from delivering rotational energy to motors by integrating a safety circuit with the drive's power switching signals. This solution meets EN13849-1, Category 3.Packaging Options•The PowerFlex 700L frame 2 is an IP00 (Open Style) panel mount drive that can be mounted in a variety of enclosures.•The PowerFlex 700L frame 3A and 3B are available in a IP20 (NEMA 1) Rittal enclosure that includes the input circuit breaker.•The majority of heat lost from the drive is transferred to the liquid coolant. Therefore, other enclosure options such as IP54 (NEMA/UL Type 12) or IP66 (NEMA/UL Type 4X) can be used and placed directly into dusty, dirty, and outdoor environments. Contact your local Rockwell Automation drive center for these packaging options.Cooling Loop OptionsA liquid-to-liquid or liquid-to-air heat exchanger, or a chiller can be used with the PowerFlex 700L drive. See page 43 for more information.Communication and Human Interface OptionsPremier Integration with PowerFlex Drives and RSLogix 5000 SoftwareFor simplified AC drive start-up and reduced development time, we've integrated Allen-Bradley PowerFlex drive configuration with RSLogix™ 5000 software. This single-software approach simplifies parameter and tag programming while still allowing stand-alone drive software tool use on the factory floor.Communication ModulesDPI communication modules provide fast and efficient control and/or data exchange over:•DeviceNet™ interface•ControlNet™ interface•EtherNet/IP™ interface•Serial communications
