Product Description:
The 131B1240 is a drive produced by Danfoss for the VLT FC 301 Automation Drives series. Within an automated plant, the unit modulates the frequency applied to induction motors so that speed and torque match real-time load demands, improving energy use and extending mechanical life. Its role fits directly into conveyor, pump, and fan systems where precise but adaptable motion is required. The drive regulates motor operation in response to process commands, allowing connected equipment to run at speeds appropriate for changing production conditions.
This model accepts a mains supply of 380–480 VAC, so it connects directly to typical industrial distribution networks without a transformer. The inverter can deliver up to 1.5 kW of electrical output, equivalent to 2.0 HP at the motor shaft, which places it in the lower-middle power range for process equipment. The unit operates with three-phase power; a balanced input reduces ripple on the DC bus and keeps motor current symmetrical. An IP20 chassis enclosure shields internal boards from accidental contact while still allowing cabinet ventilation. Normal cabinet mounting for A, B, and C frame sizes aligns the heat sink with common back-panel patterns, minimizing the need for extra mounting hardware.
Electromagnetic compatibility is supported by the integrated RFI Class A1/B filter, which limits conducted noise on supply lines and can reduce the need for an external filter. Users program and monitor parameters through the Numerical Local Control Panel, which presents key values without a graphic display while retaining direct access to operating settings. Dynamic deceleration is aided by the built-in brake chopper; excess regenerative energy is routed to an external resistor rather than returned to the mains. Cable terminations pass through standard gland plates to support organized routing within the control cabinet. The drive has an uncoated printed circuit board, so installation conditions should protect its electronics from excessive moisture and airborne contaminants. Ventilation around the chassis and heat sink should remain unobstructed to support proper thermal performance during continuous operation.
