The 1397-B075R drive is an inverter DC drive manufactured by Allen-Bradley. It is part of the Allen-Bradley 1397 series of digital drives which are of the open chassis type and can be mounted in a suitable enclosure as per their design. Its mounting should be in a dry and clean environment and all temperatures around the drive must be maintained between 0 and 55 degrees Celsius or 32 and 131 degrees Fahrenheit. The 1397-B075R drive should be mounted and applied at a standard elevation of 1000 meters or 3300 feet, where it can operate without any deration. In case of any additional 1000 meters or 3300 feet, its current rating must be derated by an additional 3%.

The 1397-B075R inverter DC drive operates with a 75 Horsepower output rating and at 460 Volts AC voltage. The “R” initial at the end of the part number classifies this drive as a regenerative type of drive which is used for reversing applications or used as an inverter DC drive. There are 3 options available for the 1397-B075R drive. These options are: control options ( DS, MB, L10, L11, DB, FS3, FS2, PE, AC and IFB), communication options (1203–GD1, 1203–GD2, 1203–GK1, 1203–GK2 and 1203–GK5), human interface options ( HAB, HAP, HA1 and HA2), and various line voltages for optional cross-references. Both analog inputs and outputs are available in the 1397-B075R drive and of these I/O, 3 are customer inputs and 2 are metering outputs.  The analog inputs are fed directly into the drive by a regulator board terminal strip.
