20AC011A3AYNAENN

The Allen-Bradley 20AC011A3AYNAENN is an adjustable frequency AC drive which provides out-of-the-box motor speed control solutions that are applicable in different industrial fields. This drive, which is a member of the PowerFlex 70 family of AC digital drives, has microprocessor-based functions with built-in protection. The 20AC011A3AYNAENN should be connected over a fuse to an input voltage of 400 Volts AC (3-phase) at 50 Hertz. The drive comes with a power rating of 5.5 kW (7.5 Horsepower), and a rated output current of 11.5 Amps. The Allen-Bradley 20AC011A3AYNAENN AC drive has 3 solutions for motor control. It can use FORCE control, standard V/Hz control with both variable and constant torque outputs, and the SVC algorithm which provides 100% torque even when the motor stalls.

The unit has a power factor of 0.98, with an efficiency rating of 97.5%. It supports Ethernet connections, and it has an intermittent current limit capability of 20 to 160%. The Allen-Bradley 20AC011A3AYNAENN is enclosed in an IP20 rated housing. It is equipped with fixed terminals to which the cables to the motor, supply cables, and signaling cables are connected. The distance between the drive and the motor must be kept as short as possible. All cables connected to motors have line-to-line and line-to-ground capacitance. If the cable is longer than this capacitance is greater. The problem with the cable capacitance is that the charging current in the cable capacitance will induce spikes in the output of AC drives. This is especially unwanted effect at higher voltages. These voltage spikes are the main reason for fast AC drive deterioration in some systems.
