Product Description:
Danfoss is a known manufacturer of industrial automation products which includes variable frequency drives. The 131N9312 VLT FC 302 Automation Drive is one of its reliable solutions for motor control applications. This drive supports a supply voltage range of 380 to 500 VAC. It operates at a supply frequency of 50 or 60 Hz with ±5% tolerance.
The maximum temporary imbalance between mains phases of the 131N9312 VLT FC 302 Automation Drive is 3.0% of the rated supply. The true power factor is nominally equal to or greater than 0.9 at rated load. The displacement power factor remains near unity, typically above 0.98. The VLT FC 302 Automation Drive offers an output frequency range of 0 to 590 Hz. When operating in flux mode, the frequency range is limited to 0 to 300 Hz. Ramp times are adjustable between 0.01 and 3600 seconds. The drive delivers a high starting torque of up to 160% for 60 seconds. Torque rise time is 1 millisecond in flux mode and 10 milliseconds in VVC mode. It complies with overvoltage category III and pollution degree 2 according to EN60664-1 standards. The drive can operate in environments with relative humidity from 5% to 95%. It meets Class 3K3 for humidity and Class 3C3 for aggressive gases. The unit is tested for vibrations up to 0.7 g.
The 131N9312 VLT FC 302 Automation Drive supports six programmable digital inputs with logic types PNP or NPN. Each input requires a minimum pulse width of 4.5 milliseconds. The drive is classified under energy efficiency class IE2. It conforms to IEC/EN 61800-3 EMC emission standards. The maximum allowable motor cable length is 150 meters.
Frequently Asked Questions about 131N9312:
Q: Why is a 1 ms torque rise time in flux mode beneficial?
A: The 1 ms torque rise time in flux mode enables extremely fast dynamic motor response. This is essential in high-speed automation where precision and reaction time are critical.
Q: How does the 0.7 g vibration tolerance impact performance?
A: The 0.7 g vibration resistance allows the drive to maintain stable performance in machinery with significant mechanical movement. It ensures reliable operation in high-vibration environments like conveyor systems or compressors.
Q: What is the benefit of supporting both PNP and NPN logic types?
A: The Danfoss 131N9312 VLT FC 302 supports both PNP and NPN digital inputs, allowing compatibility with a wider range of sensors and control systems. This flexibility simplifies integration into different industrial control panels.
Q: Why is the displacement power factor close to unity significant?
A: The displacement power factor above 0.98 reduces the reactive current drawn from the supply. This improves overall energy efficiency and reduces strain on upstream components.
Q: How does the adjustable ramp time from 0.01 to 3600 seconds help in operations?
A: The wide ramp time range allows smooth acceleration and deceleration tailored to specific load requirements. It helps reduce mechanical stress and extend equipment life.
