Allen Bradley 20AB070F0AYNANC0

The Allen-Bradley 20AB070F0AYNANC0 PowerFlex AC Drive is a variable frequency drive that has IGBT braking and Enhanced Vector control used for motor control in industrial applications with the need for torque and speed control. The drive features a flange mounting option for mounting heatsink through the back of its NEMA Type 4X and 12 enclosure, and it supports the Zero Stacking, which reduces operation space when drives are mounted side by side, and it also works at an ambient temperature of up to 122 °F. It has EMC filtering and an integral dynamic brake transistor option which proves an easy means of switching on the regenerative power with lower cost. The 20AB070F0AYNANC0 has a 3-phase operating voltage of 240V AC with an output current of 78.2A and an output power rating of 18.5kW (25HP). It is a Frame E drive with –10% minimum and +10% maximum input tolerance level at 47 to 63Hz, and an operation power factor of 0.98 across entire the speed range. Its operating efficiency is 97.5%, with a maximum short-circuit rating of 200,000A, and it offers 285V AC and 138V AC over and under voltage AC trips, respectively. The drive has a factory-fitted heatsink thermistor which provides microprocessor over temperature trips and control and it has a digitally controlled overcurrent trip with limits of 20 to 160% of the drive’s rated current. Its maximum power loss ride-thru time is 15ms with a full load, and its Logic ride-thru time is 2s.

The 20AB070F0AYNANC0 provides a transient line protection of up to 6000V, and it provides a ground fault trip as well as phase-to-phase protection by using its Metal Oxide Varistor. The drive, like most Allen-Bradley PowerFlex Drives, employs the Flux Vector Control, the Sensorless Vector Control, and the Standard Volt per Hertz Selectable Motor Control, and it uses a Sine Code PWM, with a programmable 2 to 12 KHz carrier range for control. It has a programmable output range of 0 to 400Hz, with a selectable voltage range of 0 to the rated motor voltage, and it is capable of producing a ±0.5% speed regulation across a 40: 1-speed range in Open-Loop applications using Slip compensation. The drive has several stop modes (Ramp, Coast, DC-Brake, Ramp-to-Hold, and S-curve), with 2 selectable, independent Acceleration and Deceleration times, and the kit has an overload capacity of 1150% for 60s and 150% for 3s. The 20AB070F0AYNANC0, unlike most drives in the series, does not come with a Human Interface Module, and it does not support communication ports. It has a NEMA Type 12 rated heatsink enclosure, with an operating temperature range of 32 to 104 °F, at a non-condensing 5 to 95% humidity range, and it can be installed at a height of 1000m above sea level. The 20AB070F0AYNANC0 has a net weight of 18.6Kg and approximate dimensions of 280.3mm x 555.8mm x 207.1mm.
