The 1397-B030N DC Digital Drive is a Non-Regenerative Digital DC drive by Allen-Bradley used for motor control, in industrial applications where torque control and speed control are required. It is a variable speed drive, with an IP00 (NEMA Open) enclosure, and with 10 fixed digital inputs, and 2 fixed analog inputs. It has an operational voltage of 460V AC at 50/60Hz, with an operational power of 22kW (30HP), and the drive offers a maximum short-circuit rating of 5000A. The drive has an AC Line input power of 40KVA, and it has an armature line voltage of 500V DC, with a field voltage of 300V DC. The 1397-B030N has a 1 motor service factor (SF), and it can provide 150% overload for 1 minute, at a full load rating, and 200% overload for 13s at full load rating. The drive is designed to sustain a minimum load of 5% of the drive’s full load, with 97.5% drive efficiency, and a standard displacement power factor of 0.88 (88%).

The 1397-B030N provides a 2 to 3% digital speed change with a 95% load for armature voltage control, and it also has a 1% digital speed change in closed loop applications, using a DC Tach feedback device. It provides an adjustable speed control from 0 to the rated motor speed, over a 100: 1-speed range, based on top motor speed and tachometer, and it offers a drive plus motor efficiency of 85%. The 1397-B030N drive has 2 fixed ±10V DC analog inputs with 4 to 20mA, and 0 to 10V DC ratings, configured for 12-bit plus sign at full range, and it has 2 configurable, metering analog outputs, with ±10V DC output voltage at 4mA. The drive also has 10 fixed 24V DC digital inputs, and 3 fixed 24V DC digital outputs, and the drive features Motor Overload Protection, with under and over-voltage protection. It has operating temperature limits between 0° and 55°C (32°F and 131°F) at 5 to 95% non-condensing relative humidity, and the drive can be used at a maximum elevation of 3300ft. The 1397-B030N has a total shipping volume of 477.5mm x 225mm x 300mm, and it weighs approximately 30.8Kg.
