20AD014A3AYNADG0

The Allen-Bradley 20AD014A3AYNADG0 PowerFlex 70 Adjustable Frequency AC Drive is a programmable AC drive with DeviceNet communication capability and enhanced I/O and control designed to provide global motor control solutions in a bulk of applications with torque/speed control. The 20AD014A3AYNADG0 features current limiting control, BUS voltage protection for maximizing operation, a Flying Start, PI control which eliminates the need for additional process loop, Inertia Ride-Through which ensures tripless operation even with prolonged power failure, and slip compensation which provides very accurate speed control and eliminates the need for encoder feedback devices in some applications. The 20AD014A3AYNADG0 is a frame C device with 480 Volts AC voltage, and 14 Amps, 7.5 Kilowatts normal duty output rating, and it has a 2:1 (maximum) recommended drive to power ratio.  The 20AD014A3AYNADG0 offers protection against overheating with a microprocessor, and it protects itself against phase-to-phase, phase-to-ground, and line transient protection by using metal oxide varistors installed across its circuitry. This drive provides control by using a sine-coded pulse width modulated signal with 0.01% digital accuracy, and its output voltage can be adjusted from 0 to the rated motor voltage, depending on the desired application speed.

The 20AD014A3AYNADG0 has enhanced motor control options that are selectable between the Volts per Hertz control, Sensorless Vector control, and the Vector Control method, and it is fitted with a safe torque-off circuit, a state-of-the-art protective circuit that is designed to prevent the torque energy generated by drive from acting upon motors and causing an unintentional start. The 20AD014A3AYNADG0 offers dual acceleration and deceleration times, programmed separately with 0.1-second increments to 3600 seconds (maximum), and based on application needs, it can be programmable for any of the multiple stop modes available. It has DeviceNet communication capability and a full numeric LCD HMI, which provides an easy means of configuration, control, start-up, and transfer of data and seamless integration with the factory processes. The 20AD014A3AYNADG0 is designed for use within a non-condensing 5 to 95% relative humidity condition, and it has a designated 0 to 50 degrees Celsius operating temperature range within a NEMA Type 1 enclosure. It is RCM, CE, ABS KCC, c-UL-us certified, and is shipped with a net weight of 15.0 pounds.
