Product Description:
The Danfoss 134F3021 offers reliable performance. The unit operates reliably even in extreme situations. This is part of VLT FC 360 Automation Drive which is specifically designed for industrial automation systems.
The 134F3021 drive uses Voltage Vector Control+ and Flux Basic to operate at various speeds. The drive has a power rating of 22 kW. The ambient operating temperature varies from -10 °C to +50 °C at full load. The drive dimensions are 440 mm height, 185 mm width, and 242 mm depth. Forced air cooling is used to ensure stable performance. It has wall mounting capabilities and is cabinet compatible. The drive has six adjustable digital inputs with PNP or NPN options. The RS485, Modbus RTU, and FC Protocols provide communication versatility. The overload capacity provides for 110% of typical duty. It can also handle 150-160% overload for one minute, depending on the settings. The J5 enclosure offers IP20 protection. There are two speed control modes of open-loop and closed-loop. Torque control works in both open and closed loop modes. The drive accepts 380-480 V AC 3-phase input at 50/60 Hz frequency. The system has an output frequency of up to 590 Hz. Short-circuit, overload, ground fault and motor thermal safety are all protective characteristics. The ground leakage current surpasses 3.5 mA that necessitate stronger earthing.
The Danfoss 134F3021 achieves an efficiency of about 98%. The built-in brake chopper supports dynamic braking with additional resistors. Acoustic noise levels stay below 72 decibels (A). Relative humidity operation ranges from 5 to 95% non-condensing. Storage temperatures range from -25 to +65 degrees Celsius. Derating allows operation at temperatures as high as +55 °C. The unit can work up to 2000 meters without derating.
