The 1336-MOD-E1 is a programming Terminal; a microprocessor controlled, high-performance adjustable frequency drive, which is manufactured by Allen-Bradley and belongs to the Allen-Bradley 1336 Drives series. This device has an estimated shipping size of  4 x 1 x 10’ inches (10 x 3 x 25 centimeters) and a weight of 0 pounds 8 ounces (0.23 kilograms). The 1336-MOD-E1 has input voltage ranging from 380, 415, 460, 500, 575, and 600 Volts. It also has enclosure types, including IP20 NEMA Type 1, IP00 Open style, IP56 NEMA Type 4, and IP54 NEMA Type 12, and adjustable output voltages and frequencies. It is conveniently digitally programmed from a local or remote-control panel or a communications port and has the ability to self-check itself with every power-up, which is continuous during operation.

The 1336-MOD-E1 is basically designed to control three-phase induction motors in critical industrial applications. This drive can also produce a three-phases, Pulse Width Modulation (PWM), adjustable frequency output that can be supplied to an adjustable motor speed. The output voltage of this drive is actually a function of output frequency and is adjusted so as to match the motor parameters to find the optimum and effective motor performance. The 1336-MOD-E1 is a Variable Speed Drive (VSD) with industrial electric motors control, which adjusts motors speed externally. It is used in process control and helps save energy in plants that use many powerful electric motors. The use of this device in process control matches the motor speed to the required operations; this actually compensates for deviations in the process’s variables. The 13336-MOD-E1 drive is available in different sizes, ranging from about 5 to 4000 Horsepower (HP), and various speeds up to 3600 RPM.  This module comes with reduced operating costs and low maintenance, which are as a result of transferring torque from motors to the driven mechanism across an air gap without shaft-to-shaft physical connection preferably known as a disconnected connection. This connection reduces vibrations that increase the lifespan of the module’s seal and bearing.
