Product Description:
The 131X6122 is an AC variable frequency drive built by Danfoss for centrifugal pumps and fans in process lines. It belongs to the FC 111 Flow Drives series, a subset of VLT products optimized for flow-dependent loads. By modulating the stator frequency supplied to an induction motor, the unit lets control systems match pump speed to real-time demand, lowering energy consumption and reducing water hammer without requiring mechanical throttles.
The drive delivers a continuous output of 18.5 kW, which is the maximum mechanical power it can transfer to the motor shaft under normal ambient conditions. Supply terminals accept three-phase mains at 3 × 380–480 V AC, so the drive installs directly on standard industrial networks without transformers. Its housing carries an IP20 rating when mounted on the supplied back plate, limiting installation to clean electrical cabinets while allowing heat to dissipate through natural convection. A reinforced coating on the control boards guards against conductive dust and humidity that often accumulate around pump stations. Because the unit is supplied without a brake unit, braking energy must be managed by the motor load or an external resistor if rapid deceleration is required. Local setup through front-panel keys is not possible because the drive does not include an LCP; parameter entry must be completed through a remote panel or serial link.
Within the VLT Flow Drives product group, model designation 111 indicates support for proportional-integral control functions and preconfigured macros for liquid-handling equipment. Cabinet layouts can be adapted because the drive has no factory-installed power input switchgear, allowing disconnects and circuit protection to be sized according to national codes and motor full-load current. Application-specific process menus support operation in booster sets, irrigation skids, and wastewater aeration blowers. These menus provide settings for flow-related applications without requiring mechanical control devices. External protective components can be selected according to the electrical requirements of the installation, while the remote interface provides access to operating parameters and process controls.
