The Allen-Bradley 1395-173973 drive is a microprocessor which is available in the armature, regenerative, four-quadrant, and two-quadrant field orientations. The other features in 1395-173973 include a fused AC input and a DC contactor. It has programmable functions which include presser and job speeds, independent acceleration, and a tapered current limit. Its protective features include feedback loss, field economy, field loss, instantaneous overcurrent, and motor overload protection. Also, there is an interface which controls signals and it is used to transfer information from one device to another.

The 1395-173973 has programmable terminals which are used to monitor its operation. The programmable terminals are offered in two packages which are door-mounted and digital handheld terminals. Moreover, the 1395-173973 has an AC line reactor which is used to protect the power bridge from rapid rate current changes. Additionally, the 1395-173973 has the AC current feedback which is used to provide current feedback information to the Switcher/PSI board. The PSI/Switcher board is useful because it rectifies the scales and the feedback scales because the DC voltage represents the current feedback. The signals are then sent to the Main Control Board.

The other important feature that the 1395-173973 has is surge suppression which refers to a power board which protects the armature power bridge from line surges and line voltage spikes. Also, there is the line reactor which plays a major role in protecting the power bridge SCRs from the rapid rate of the current changes. The 1395-173973 has voltage transient protection which protects the SCRs against voltage transients. The 1395-173973 has the main control board which controls all its functions.
