The Allen-Bradley 20AB028F0AYNANC0 PowerFlex 70 Digital AC Drive is a flange-mounted variable frequency drive in the Allen-Bradley PowerFlex 70 Series, which provides enhanced motor control in most industrial applications. This drive, which comes with an IP20 (NEMA Type 1) enclosed front chassis and IP66 (NEMA Type 4x/12) enclosed rear heatsink, is designed to provide instant performance in a variety of applications, and it features selectable motor control methods for outstanding control and performance. The 20AB028F0AYNANC0 has a 3-phase (6-pulse) AC input voltage of 240 Volts at 60 Hertz, and 28 Amps and 7.5 kW (10 Horsepower) output rating. It also has -/+10% voltage tolerance at 47 to 63 Hertz, with a displacement power factor of 0.98 across entire speed range, and it has an operational efficiency of 97.5%. This drive has 200,000 Amps rated short-circuit protection, with a >2:1 drive-to-motor ratio, and it provides voltage trips of up to 285 Volts and 138 Volts (for both overvoltage and under voltage). The 20AB028F0AYNANC0, like all drives in the series, has programmable over temperature trips at the heatsink, and it also has a digitally controlled overcurrent trip, with limits within 20% to 160% of the drive’s rated output current. This drive provides 6000 Volts max. line transient protection, with Ground Fault plus phase-to-phase protection at the outputs, and this drive is designed to ride thru 15 milliseconds of power loss.
The 20AB028F0AYNANC0 provides enhanced motor control using the SVC (sensorless vector control) and this drive provides output control using the Sinusoidal PWM signal that is programmable with 4 KHz (default) carrier frequency. It has a selectable output voltage between 0 and the rated motor voltage, with a programmable output frequency range of 0 to 400 Hertz, and it offers 0.5% frequency control in vector control mode across an 80: 1-speed range. It also provides 0.1% speed regulation in vector mode across a 120: 1-speed range, with +/-10% torque regulation, and unlike many drives in the Powerflex series, it does not come with a feedback device. This drive has different Acceleration and Deceleration times programmable from 0 to 3600 seconds, with an intermittent overload capacity of 115% for 60 seconds and 150% for 3 seconds, and it provides electronic motor overload protection. The 20AB028F0AYNANC0, unlike some drives in the series, does not have a Safe Torque-off feature, but it supports IGBT braking and EMC-rated filtering. It has a working temperature range of 32 to 122 degrees Fahrenheit without de-rating, with a storage range of –40 to 158 degrees Fahrenheit, and it has a non-condensing relative humidity range of 5 to 95%. The 20AB028F0AYNANC0 has a total operational heat loss of 318.5W, and it is designed to resist an operational shock of 15G and a vibration of 1G.
