Allen Bradley’s 1395-B80-NE1-P30 part belongs to the family of DC Digital drives. It is a Non-regenerative 460 Volt type drive, with a Horse Power (HP) of 250, which uses a microprocessor to determine firing signals. For 250 HP it has an armature shunt of 1000 A. This unit comes with an adapter board, an interface, a microbus, two ports, and a programming terminal. It has a DC contactor to connect the DC motor to the armature bridge output, and its LCD screen will display the unit’s current running mode, such as “jog” or “run”. With keypads on both versions of the terminal (handheld or door-mounted) to monitor and change real-time parameter values, start and stop the drive, and monitor the unit’s fault information, the 1395-B80-NE1-P30 unit is used mostly in high precision applications such as paper production machines, winders, and crushers.

This unit’s two discrete digital outputs, at 125 Volts AC, have a contact rating of 0.6 A; at 30 Volts DC, its contact rating is 0.2 A. Its four preprogrammed analog to digital inputs are 11-bit; its conversion process provides 4.88 millivolts per bit resolution.

This unit should be stored in a dry and clean place, within an ambient temperature zone of 0 to 65 degrees Celsius (32 to 149 degrees Fahrenheit), within a noncondensing humidity range of % to 95%. Its maximum altitude is around 3,300 feet (or 1,000 meters).

Its output voltage is around 500 Volts DC, with an RS-422 communication port for programming. Its standard acceleration and deceleration are 0.1 seconds up to 6554 seconds and can be independently programmed. Always ensure that the power supply is properly connected, so that constant flux may be fed into the system at all times. Its armature current is usually the current to derive its torque from the motor torque.

This part has been tested under NFPA standards and may be kept in a NEMA Type 1 Enclosure. It has options for speed selections in 6:1, by utilizing various programming commands, and it has dedicated communication options to choose from, such as an interface between the drive and a remote desktop, or something like Ethernet or USB. The 1395-B80-NE1-P30 is designed with universal standards, with most of the settings being the same or similar throughout the world to ensure uniformity. Go through the instruction manual for setup instructions at least once to avoid unintentional damage to the module.
