The Allen-Bradley 1397-B030R-HA2 Digital DC Drive is a variable speed DC regenerative drive in the Allen-Bradley 1397 family of adjustable speed drives, which provides digital motor control in a variety of applications requiring excellent speed control. It makes use of a state-of-the-art digital current regulator and of speed regulator algorithms which provide repeated and precise DC motor control, and it also features programmable adjustments, stop modes, and set points, and it can provide full torque at a stall. The 1397-B030R-HA2 has a drive rating of 22kW (30HP), at an operating line input voltage of 460V AC, and it has an AC line input current of 45A. The 1397-B030R-HA2, unlike most Digital drives, it provides speed control via armature-controlled output voltage, which directly correlates with the motor speed, and it provides an armature output voltage of 500V DC with 300V DC Field voltage. It also offers a 52A Armature output current, with a 10A Field output current, and it provides an output overload capacity of up to 150% of the rated full load for 60s, and of 200% for 13s. It has an input tolerance of -/+10% at 48 to 62Hz, with a rated displacement power factor of 0.88, and its control efficiency is 98.0%.

The 1397-B030R-HA2 offers an adjustable speed range between 0 and the rated motor speed, over a 100: 1-speed range, and it also offers a 2 to 3% speed change with a 95% load, via the Armature speed regulation with w/IR compensation. The 1397-B030R-HA2 has 10 Digital 24V DC control inputs, 3 Fixed 115V AC/30V DC contact outputs, 2 programmable Reference inputs, 1 Analog 10 to 250V DC Tachometer input, and 2 programmable AND non-isolated -+10V DC analog output (Analog Output1, and Analog Output2). It is configured using a HIM module with an LCD, a digital pot, and Programmer/Controller capability, which also displays diagnostic information in plain text format, and it offers 2 separate and programmable Acceleration and Deceleration times. The 1397-B030R-HA2 has a maximum operating temperature limit of 55°C (131°F) without de-rating in an open chassis, and it is operable at an altitude of 1000m without de-rating. It is CE, UL, and CSA certified, and it weighs 30.8Kg (68.0lb) with approximate dimensions of 477.5mm x 300.0mm x 270.5mm (18.80in x 11.81in x 10.65in).
