Product Description:

The Danfoss 131F9966 Drive is a versatile motor control solution. It operates with a 3-phase voltage range of 380–500 V AC. This drive is suited for applications that require consistent performance and effective energy management. It is available in IP20, IP21, IP55, and IP66 enclosures making it suitable for a wide range of conditions.

The 131F9966 has excellent electrical requirements for sustained operation. It has output currents ranging from 1.3 A to 16 A across the 3x380-440 V range and 1.2 A to 14.5 A for 3x441-500 V. It is from the series of VLT FC 302 Automation Drives. The drive has been engineered to fulfill stringent performance standards with a vibration resistance of 1.0 g. It functions well in situations with ambient temperatures ranging from 5% to 93% humidity. It ranges in weight from 4.7 kg to 14.2 kg depending on the enclosure type. The drive has a speed control range of 1:100 in open-loop mode and 1:1,000 in closed-loop mode with excellent accuracy. The speed accuracy in open-loop mode is ±8 rpm (30-4,000 rpm) whereas in closed-loop mode it is ±0.15 rpm (0-6,000 rpm). The drive provides accurate torque control with a maximum inaccuracy of ±5% of rated torque. The system has a response time of ≤ 2 ms and an output frequency resolution of ±0.003 Hz, allowing for more precise motor control.

The VLT FC 302 can accommodate cable lengths of up to 150 m (500 ft) for shielded motor cables and 300 m (1000 ft) for non-shielded cables. The drive delivers output power ranging from 0.5 to 10 hp (0.37-7.5 kW), meeting a wide range of power requirements. At maximum load, the drive has a power loss of only 35-255 W, resulting in an efficiency of 93%-97%. It comes with safety features such as Safe Stop, fault prevention and overcurrent protection, assuring safe and dependable operation in industrial environment.
