20AD027A0AYNAENN

The Allen Bradley 20AD027A0AYNAENN is an advanced variable-frequency AC drive that belongs to the PowerFlex 70 product range. An Ethernet interface is integrated with the drive. The 20AD027A0AYNAENN does not include a built-in internal brake resistor or HMI. The drive supports a standard control algorithm and includes an internal brake IGBT. Rated for 480 Volts AC input, the 20AD027A0AYNAENN provides 27 Amps at 15 kilowatts at the output with 3-phase input which derates to 50% of rated values with 1-phase input. The 20AD027A0AYNAENN supports sensorless vector, Volts per Hertz, and vector control with FORCE Technology. It can be used with an LCD HMI module which is available as an option. The control method supported by the 20AD027A0AYNAENN is a sine coded PWM with a programmable carrier frequency. The output voltage range is from 0 to rated motor voltage. Selectable motor control options include sensorless vector with full tuning, standard V/Hz with a full custom capability and vector control.

The 20AD027A0AYNAENN supports the following stop modes: ramp, coast, DC-brake, fast brake, ramp-to-hold, and S-curve. It also supports two independently programmable acceleration and deceleration times each of which can be programmed from 0 to 3600 seconds in 0.1-second increments. The drive supports Class 10 motor overload protection according to NEC article 30 and over-temperature protection according to NEC article 430.126(A)(2). The D-frame 20AD027A0AYNAENN weighs approximately 20.4 pounds and its NEMA type 1 enclosure has the following dimensions: 350 millimeters in height, 219.9 millimeters in width, and 179.7 millimeters depth. The maximum altitude at which derating does not occur is 3300 feet.
