VLT® AQUA Drive FC 202
Design Guide

4 Product Family Overview

4.1 VLT® Drives
Danfoss offers 3 types of AC drives in different-sized enclosures for a wide range of applications, with power ratings from 0.25–1200
kW (0.34–1350 hp).
Standalone drives (frequency converters)
The Danfoss standalone drives are so robust that they can be mounted outside of cabinets virtually anywhere, even right beside the
motor. Equipped for the toughest of environment, they suit any application.
More uncompromising features:
• Enclosure sizes with protection ratings up to IP66/UL Type 4X.
• Full EMC compliance according to international standards.
• Ruggedized and coated PCBs.
• Wide temperature range, operating from -25 to +55 °C (-13 to 131 °F).
• Motor cable lengths up to 150 m (492 ft) for shielded cables and 300 m (984 ft) for unshielded cables.
Enclosed drives
Danfoss enclosed drives are designed with the installer and operator in mind to save time on installation, commissioning, and main-
tenance. The enclosed drives are designed for full access from the front. After opening the cabinet door, all components can be
reached without removing the drive, even when mounted side by side. Several cooling options, including back-channel cooling,
provide optimum adaption to the installation location and application.
More time-saving features:
• An intuitive user interface with an award-winning local control panel (LCP) and common control platform that streamlines start-
up and operating procedures.
• Robust design and advanced controls make Danfoss drives virtually maintenance free.
System modules
The compact design of the system modules makes them easy to fit even in small spaces. Integrated filters, input fuses, options, and
accessories provide extra capabilities and protection without increasing the enclosure size.
More space-saving features:
• Built-in DC-link reactors for harmonic suppression eliminate the need for higher loss external AC line reactors.
• Optional built-in RFI filters are available throughout the power range.
• Regen terminals are available within the standard enclosures (for enclosure sizes D, E, and F).
• In addition to the many valuable features that the Danfoss drives offers as standard, there are several other control, monitoring,
and power options available in pre-engineered factory configurations.

4.2 Product Overview of the VLT® AQUA Drive FC 202
The VLT AQUA DriveFC 202 is a drive for controlling AC induction motors, permanent magnet synchronous motors, and synchro-
nous reluctance motors (SynRM motors). As other Danfoss AC drives, the VLT AQUA Drive is motor independent, meaning that the
drive can be connected to any brand of motor, thus providing great flexibility when designing an installation.
The FC 202 is designed for water and wastewater applications. The integrated SmartStart wizard and the quick menu Water and
Pumps guide the user through the commissioning process. The range of standard and optional features includes:
• Cascade control
- Cascade for multi-pump operation with run-time balancing of pump running hours. Basic cascade control built in as stand-
ard with a capacity of up to 3 pumps. Systems with multiple variable-speed pumps require the VLT® Extended Cascade Con-
troller MCO 101, the VLT® Advanced Cascade Controller MCO 102, or the license code option for Digital Cascade via built-in
MODBUS.
• Multi-master cascade control
- Redundant cascade system with up to 8 masters per system. If the primary master stops working, a back-up master auto-
matically takes over.
• Dry-run detection
- This feature prevents damage to the pumps by avoiding dry-running and pump overheat.
• End-of-curve detection
