The Allen-Bradley 1305-BA06A is part of the bulletin 1305 Adjustable AC Drive. Adjustable Frequency AC drives are also known as Variable Frequency Drives (VFD) and Variable Speed Drives (VSD). These terminologies refer to the same device that is primarily used for implementing bacis ON/OFF and modulating speed control as well as implement proper start-up and shutdown of a connected AC motor.

The 1305-BA06A is powered by providing an input voltage of 380-460VAC, 3-phase along a frequency of 50-60 Hz with operational voltage of 340-500VAC, 47-63 Hz. It has an input kVA rating of 4.6 kVA with power factor displacement of 0.8 (lagging). It has an efficiency of 97.5% and power dissipation of 73 Watts.

The output characteristics of the 1305-BA06A include an output current of 6.0 Amperes, output frequency of 0.00 - 400.00 Hz and output power of 2.2 kW or 3 HP.

The 1305-BA06A is provided with I/O terminals that consists of Two (2) Programmable outputs, in One (1) Analog output that delivers output signal of 0-10VDC, Three (3) discrete inputs that are configurable for 2 or 3 wire sensor, Three (3) discrete inputs that may be assigned to Seven (7) preset speeds and Two (2) Accel/Deccel profile, One (1) Momentary Switch for JOG operation, Two (2) Analog Inputs and One (1) Potentiometer input for drive’s speed reference.



Both are obsolete applications that are used for offline and online configuration of the drive, remote operation, testing, parameters compare and drive configuration backup.

The 1305-BA06A comes with an input power of 4.6 KVA and an operational voltage ranging from 340 Volts to 500 Volts. It has a total power dissipation of 73 Watts and a machine efficiency of 97.5%. Additionally, the 1305-BA06A has a NEMA standard 1 certified enclosure, with a surrounding temperature of up to 50 degrees Celsius. It works best at a relative humidity range between 0 and 95% (non-condensing), with a standby temperature of 40-70 degrees Celsius. The 1305-BA06A has an operating vibration of 1g.

This adjustable Frequency AC drive is capable of controlling the starting, stopping, forward and reverse movement, of a motor as well as modulate speed through an external potentiometer 10 Kohms at 1 Watt. The 1305-BA06A is adapted with a 100 K ohm input impedance, at a resolution of 10 bit. The 1305-BA06A also comes with protective features like a DC-monitored voltage and a temperature sensor to prevent exceeding the factory pre-set level. This drive measures 210 millimeters x 195 millimeters x 175 millimeters and weighs around 4.2 kilograms.
