The electronic device that captures and regulates the electrical energy sent to the motor is known as a drive. The drive modifies the amount and frequency of energy fed to the motor, which indirectly controls the motor’s speed and torque. Based on the voltage type, the two main categories of drives are; AC drives and DC drives. DC drive is one of the most reliable, efficient, inexpensive, user-friendly, and easy technology to implement. They also have many advantages over AC drives especially for regenerative and higher power applications. They have many industrial uses as they can give us very precise control. While in some applications we can see VFDs and AC drives as an alternative, in applications like cranes, hoists, elevators, spindle drives, winders, paper manufacturing machines, crushers, etc., we still have to use them.

Allen Bradley MicroLogix 1200 PLC PLCs are programmable controllers that are specially designed for applications in the industry. Before the advent of PLC, the industrial control system was a relay contractor system. However, these relay systems had many disadvantages, such as complicated wiring, longer durations for designing and production, problematic maintenance, fewer functionalities, and a variety of adaptations difficulties. PLCs use programmable storage for storing the instruction set of logic, timings, counting, and mathematical operations. They act as a controller in the industrial PC, adapted for control or production operations like assembly lines, fault diagnosis, robotic applications, and the ones which required great precision. There are many industrial component producers who are designing and manufacturing PLCs globally, and because of that, there is intense marketing competition. Two of the big names in this regard are Allen Bradley and Omron. We will be seeing the...

Allen Bradley TLY & TL Servo Motor TL-A220P-HJ32AA For applications where precision, accuracy, and control of rotation are required, servo motors have been used for a long. Servo motors are those kinds of electromechanical tools that have provided the convenience of feedback based on which the user can monitor the movement of the motor degree by degree. According to the user’s application, different servo motors are available: continuous rotation, linear rotation, and positional rotation servo motors. TL series servo motors are low inertia servo motors, which means they can control the load’s velocity very well and help control the load’s acceleration and deceleration. The low inertia feature in these servo motors helps them to preserve their state of uniform motion or state of rest longer. These types of servo motors come with different types of frame sizes. The frames are of metric and NEMA standards to make mounting of these motors easy and compact according to the desired...
The term HIM stands for Human Interface Module. It’s basically a user interface that enables human operators to engage and interact with a drive, machine, or a system. HIMs are commonly used in the industrial context, and you’ll often come across them in industrial environments alongside AC drives or Variable Frequency Drives (VFDs). They allow factory operators to start and stop process cycles, adjust operating set points, and perform other necessary functions required to control and interact with industrial drives. HIMs are also software-based, so they replace physical and hard-wired controls with software control parameters, allowing easier adjustment of drive operating parameters. Thus, with a HIM you can upload individual sets of parameters for your host drive and any other peripherals connected into the HIM. Other functions include: Accepting input data obtained from human operators Processing the input data Data logging Real-time information display of the operating conditions...

The term VFD stands for Variable Frequency Drive. It is a type of motor controller which drives an electric motor by varying the frequency and voltage supplied to that motor. Variable Frequency Drives (VFDs) are also known as AC Drives, Inverters, Variable/Adjustable Speed Drives, Inverters, Variable-Voltage Drives, Microdrives, Frequency Converters, or Variable Frequency Inverters (VFIs). Frequency, given in Hertz (Hz), is directly related to motor speed in revolutions per minute (RPM). Thus, by adjusting the input frequency the motor speed can be varied accordingly. For example, the higher the supply frequency, the more RPMs the motor will exhibit. VFDs are best suited for applications in which an electric motor is not required to run at full speed, as they can ramp down the supply voltage and frequency to meet the requirements of the motor’s load. In case there is a change in the application’s motor speed requirements, the VFD can be set to ramp up or turn down the motor speed as...

PLCs and CNCs are two major categories of digital controllers employed in different industrial control applications. On a surface level, it’s easy to group them together since they are both run by programs, digital processors, and they both interface with input and output devices. For example, if you ask a systems programmer whether a CNC controller can be used in place of a PLC system, the answer could be a frustrating variation of “Yes or No.” It’s therefore important to identify the differences between the two control systems, as discussed in this article. In electrical terms, PLC stands for Programmable Logic Controller. It is a compact, special-purpose computer designed to perform logic operations to control different electro-mechanical systems. Initially, PLCs were developed to perform the functionalities of hard-wired relays in the automotive industry. Today, Programmable Logic Controllers (PLCs) are widely used to automate manufacturing processes, assembly lines, and different...
Both Eaton S801+ and Eaton S811+ industrial soft starters, products of Eaton’s electrical business are very compact and smart electronic devices to smoothly start three-phase induction motors. Both share many common features and are distinct slightly from each other. This article focuses on some of their major characteristics which could be related to their power or control actions, hardware features, and/or environmental specifications with reference to applications, and outlines all similarities as well as differences. Both soft starters S801+ and S811 are very compact so they could be retrofitted in existing wye-delta starters, NEMA (National Electrical Manufacturers Association) and IEC (International Electrotechnical Commission) starters, or other soft starters. As this feature of S801+ and S811+ starters makes replacement of the whole system or structure avoidable, so huge expenses are emitted. This feature makes these soft starters more usable and demanding. Eaton Corporation...
A Soft Starter is a device that provides an alternative startup method to a typical AC motor with fewer power requirements at start-up. It reduces the amount of drawn inrush current and limits the motor starting torque; this helps reduce potentially damaging mechanical and electrical shocks on the motor system. When a soft starter is added to a motor’s circuit, it continuously regulates the motor’s supply voltage during the start-up phase. This means that the motor will gradually adjust to the machine’s load behavior. So, the soft starter provides the motor with a smooth acceleration up to full speed. This improves the operating behavior and lengthens the service life of your motor; it also smooths workflows. As the name suggests, soft starters are mainly used in the start-up phase of electric motors or other mechanical operating equipment. But they can also be used to stop, accelerate, reverse and protect such equipment. Moreover, they are used to reduce motor heating in case of...
