Danfoss VLT Aqua Drive FC 202 – Optimized for Water & Wastewater Applications

The Danfoss VLT Aqua Drive FC 202 is a specialized AC drive designed for water and wastewater systems as well as other variable torque applications.  “Aqua Drive” indicates its primary focus: controlling pumps, blowers, fans, and compressors with maximum efficiency. This drive is built with intelligence tailored to fluid handling, making it ideal for municipal water plants, irrigation systems, industrial pumping stations, and similar uses. It automatically optimizes motor control across all speeds and fluctuating loads common in these environments. For example, the FC-202P90KT4E20H1XGCXXXSXXXXA0BXCXXXXDX has a digital cascade controller for multi-pump systems and can perform functions like “deragging” (an automated cleaning sequence to remove debris from pump impellers) to prevent downtime. The result is smoother operation and extended equipment life in critical infrastructure.

Key Features of the VLT Aqua Drive FC 202:

• Pump-Specific Protections: FC 202’s software includes features to prevent water hammering in pipelines and to avoid sudden pressure spikes. This protection of assets means valves, pipes, and pumps see less stress during stop/start or load changes, reducing maintenance needs. The drive can also detect pump wear or leaks and adjust performance, accordingly, ensuring more reliable, stable operation even if an issue arises. In multi-pump systems, an FC 202 can act as a backup master controller – if one drive or pump fails, another takes over seamlessly to keep your system running.
• Energy Efficiency: Danfoss designed FC 202 for maximum energy savings in variable torque applications. Advanced control algorithms and Automatic Energy Optimization feature continually adjust output to minimize losses. In fact, the VLT Aqua Drive is documented to provide a first-year energy cost savings of 10–30% compared to traditional drive solutions. Over the drive’s life, users benefit from lower electricity usage and reduced cooling requirements. Additionally, a unique thermal management design called back-channel cooling vents about 90% of the drive’s waste heat directly out of the enclosure, rather than into the control room. 
• Electromagnetic Compatibility: To suit modern industrial settings, the VLT Aqua Drive FC 202 comes with integrated RFI filters and DC link chokes as standard. These components drastically reduce electromagnetic interference (EMI) and harmonics fed back to the power grid. As a result, the drive meets strict EMC standards without requiring many external filters. Your sensitive instrumentation and networks are less likely to suffer interference, and utility power quality is protected.

Specifications – FC 202 Aqua Drive:

• Power Range: Three-phase models cover from ~0.25 kW up to 1.4 MW (at higher voltages) in output power, depending on the variant. For instance, standard 380–480 V units span approximately 0.37 kW to 1 MW, while high-voltage 525–690 V units extend up to 1.4 MW. This means the FC 202 can drive everything from small 1/3 HP circulation pumps to giant 1000+ HP pipeline pumps.
• Voltage Ratings: Options include 200–240 V (single-phase up to 22 kW or three-phase up to 150 kW), 380–480 V three-phase (up to 1000 kW), and even 525–600/690 V for larger drives. This flexibility ensures a compatible model for nearly any power system without requiring transformers.
• Overload Capacity: Typically rated for 150% overload for 60 seconds (and even higher short-term overloads) in standard configurations. This allows the drive to handle start-up surges or momentary load spikes (for example, a jam in a pump or rapid changes in flow demand) without tripping. Certain heavy-duty ratings are available if your application demands continuous higher torque.
• Environmental Tolerance: Standard operating temperature is -25°C to +50°C without derating, suitable for both cold pump houses and hot equipment rooms. With proper de-rating or optional cooling, some models can go even higher. The drives also feature intelligent cooling control (fan speed adjusts to load/temperature) to reduce noise and energy use. VLT Aqua Drives are designed to run 24/7 in tough conditions, making them very reliable for critical infrastructure.
• Dimensions: The physical size of FC 202 drives depends on the power rating and enclosure. A smaller unit (e.g., a 5.5 kW / 7.5 HP drive) might be only about 268 x 90 x 205 mm and ~10 kg, which fits easily in a cabinet. On the other end, the largest 1 MW+ units in an IP54/IP55 floor-standing enclosure can be over 1 meter tall (approx. 1027 x 375 x 375 mm) and weigh up to 200–300 kg.

Danfoss VLT FC 302 Automation Drives – Advanced All-Purpose Industrial Drive

The Danfoss VLT Automation Drive family is a versatile AC drive series designed for automation and motion control in industrial settings. It comes in two performance levels – the FC 301 (standard version) and the FC 302 (high dynamic version with extended features). Our focus here is on the VLT FC 302 Automation Drives, which incorporates all the capabilities of the 301 and adds further functionality for demanding applications. The FC 302 is engineered to control both standard asynchronous AC motors and permanent magnet motors with equal finesse. From conveyors, mixers, and packaging lines to cranes, extruders, and marine propulsion, drives such as the FC-302P1K5T5E20H1XXXXXXSXXXXAXBXCXXXXDX can adapt to virtually any fixed or variable torque application. With the FC 302, Danfoss delivers a truly “all-in-one” drive solution that can be tuned to perform optimally in many different contexts – all while maximizing uptime and minimizing life-cycle costs.

Key Features of the VLT Automation Drive FC 302:

• High Performance Motor Control: The FC 302 employs sophisticated control algorithms, including flux vector control and sensorless vector control, to achieve precise speed and torque regulation across the entire speed range. It can even control motors at near-zero speed with high torque repeatability, which is critical for positioning and synchronization tasks. Unlike basic drives, the FC 302 also has a dedicated permanent magnet (PM) motor control mode, enabling use with high-efficiency PM or brushless servo motors. This flexibility means you can standardize FC 302s for different motor types in your facility. The drive’s smart logic controller and optional Motion Control Option (MCO) modules allow it to handle complex tasks like electronic shaft synchronization, positioning sequences, and cyclic load sharing without an external PLC in some cases. In short, precision and adaptability are hallmarks of FC 302’s motor control.
• Expanded I/O and Safety Functions: Compared to the FC 301, the FC 302 comes with additional built-in I/O and safety features to meet modern automation standards. For example, the FC 302 has a sixth digital input that doubles as a safe torque off (STO) / safe stop input. This SIL2/SIL3-rated safety feature lets you integrate the drive into emergency stop circuits – cutting motor power almost instantly when triggered, to help protect personnel and equipment. The drive also provides dual configurable relay outputs (versus a single relay in the FC 301) for more flexible monitoring or fault indication schemes. Analog inputs on the FC 302 support bipolar signals (-10 to +10 V). By contrast, the simpler FC 301 inputs are 0-10 V only. All these enhancements in the FC 302 translate to greater integration capability – the drive can be the central hub of motor control, safety interlocks, and feedback devices on your equipment.
• Communication and Networking: Like most Danfoss drives, the VLT Automation Drive is connectivity friendly. The FC 302 supports a wide array of industrial communication protocols right out of the box, ensuring it can integrate into your existing automation system with ease. Standard fieldbus options include PROFIBUS, DeviceNet, and CANopen, and on the Ethernet side it can speak PROFINET, EtherNet/IP, and Modbus TCP among others. Additionally, all FC 302 drives come with a built-in RS-485 serial port (Modbus RTU) for basic communications and easy PC configuration via Danfoss’s MCT 10 software. This rich connectivity ensures the FC 302 can be a team player in networked automation, enabling features like remote monitoring, parameterization, and even cloud-based diagnostics (with external IIoT gateways). You can have multiple drives share load or speed settings over a network and integrate the VFD’s status into SCADA or MES systems for smarter control of your operations.
• Energy Efficiency and Thermal Design: The FC 302 is built with efficiency in mind, both in how it drives the motor and how it manages its own power usage. It inherits Danfoss’s Automatic Energy Optimization (AEO) function that dynamically minimizes motor magnetization current to reduce energy draw when full torque isn’t needed. It also features an over-voltage control that can extend deceleration times to avoid wasting energy as heat in braking resistors (great for high-inertia loads that need to slow down without a big resistor). In terms of cooling, many FC 302 units use the same back-channel cooling concept as the Aqua series, exhausting most heat directly outside the panel. On smaller models, natural convection cooling is often sufficient, meaning fewer or no fans, less noise, and reduced maintenance. Larger units come with easily replaceable fans and intelligent fan control to optimize cooling. As a result, the FC 302 boasts low overall lifetime costs – high efficiency and less strain on components mean you save on energy and the drive lasts longer with minimal servicing. Danfoss VLT drives are known for running for many years in the field, and the FC 302 is no exception.
• Range of Sizes and Power: The FC 302 series covers a vast power range, allowing one drive platform to be used for both small machinery and very large industrial motors. Models start around 0.25 kW (1/3 HP) for the low-voltage 240 V units and go up to ~1.2 MW (1200 kW) for the highest 690 V versions in heavy-duty use. A common subset is the three-phase 380–480 V line, which spans roughly 0.75 kW to 315 kW in normal duty ratings. For example, an FC-302P2K2T5E20H1 part number corresponds to a 2.2 kW (3 HP, 380–480 V) drive, while FC-302P5K5T5E20H1BXXXXXSXXXXAXBXCXXXXDX is a 5.5 kW (7.5 HP) model – and the series continues through 11 kW, 22 kW, 55 kW, 90 kW, etc., up to the hundreds of kW. Despite the wide span, all these drives share a common interface and programming style, making it simple to scale up or down as your needs change.
