The VLT AQUA Drive FC 202 combines motor control with functions developed for water and wastewater systems, including pressure regulation, pump sequencing, and low-demand operation. The VLT AutomationDrive FC 302 provides configurable speed and torque control for machinery, with support for multiple motor technologies, motor feedback, and application-specific braking requirements.
Danfoss VLT AQUA Drive FC 202
The FC 202 series regulates pump operation by connecting motor speed to the requirements of the water system. In closed-loop operation, its internal PID controller compares a process measurement, such as pressure or flow, with the required setpoint and adjusts motor output accordingly. Feedback handling supports single-zone control and more complex arrangements using multiple feedback signals. These signals can be averaged, combined, or selected by their minimum or maximum value, allowing the control response to reflect conditions across different measurement points.
Pump-specific functions address changing demand and operating conditions. Sleep mode stops the motor after demand remains low for a configured period and restarts it when the wake-up requirement is reached. Available functions also include dry-run detection, low-flow detection, end-of-curve detection, pipe fill mode, and deragging. Cascade control and motor alternation support systems with multiple pumps, with the available arrangement depending on the controller configuration and installed options. SmartStart and the Water and Pumps quick menu organize the initial application settings.
The control interface includes two analog inputs configurable for 0–10 V or 0/4–20 mA, along with RS485 serial communication. Optional interfaces include PROFIBUS, PROFINET, EtherNet/IP, and Modbus TCP for integration with plant controls. Automatic Motor Adaptation measures motor electrical characteristics to improve the drive’s motor model, while the electronic thermal relay estimates asynchronous motor heating from current, frequency, and operating time. Enclosure selection is also configuration-specific, with IP20, IP55, and IP66 versions addressing different installation requirements.
Part number | Typical motor shaft power | Input supply | Continuous output current | Enclosure |
5.5 kW | Three-phase, 380–480 VAC | 13 A / 11 A | IP55 | |
30 kW, normal overload | Three-phase, 380–480 VAC | 61 A / 52 A, normal overload | IP20 |
Danfoss VLT AutomationDrive FC 302
The FC 302 series supports induction motors, surface and interior permanent magnet motors, synchronous reluctance motors, and permanent magnet assisted synchronous reluctance motors. Its control platform includes VVC+ and flux control, with operating modes that use either a calculated motor model or measured motor feedback. Sensorless control supports applications without a shaft feedback device, while closed-loop flux control uses feedback to regulate motor behavior more closely. The required motor technology, speed range, and torque response determine the appropriate control configuration.
Overload capacity is particularly relevant where machinery must accelerate a load or accommodate temporary increases in torque. For the 380–500 VAC configurations, high-overload classifications are 160% for 0.37–22 kW and 150% for 30–75 kW, for one minute in a ten-minute cycle. Programmable torque and current limits provide additional control over loading. Brake-chopper versions can direct regenerated energy into a suitable external brake resistor during deceleration, while mechanical brake control functions coordinate drive operation with an external holding brake.
The FC 302 can be expanded through communication, feedback, I/O, and safety options. Encoder and resolver interfaces must be selected to match the connected feedback device, while network options establish the required connection to the machine controller. Integrated Motion Controller functionality adds positioning, homing, and synchronization on configurations equipped with the appropriate software. The S067 software designation identifies the IMC configuration, making software selection an essential consideration when the application requires position control.
