Considerations for buying automated parts

What are automated parts used for?

Automation is crucial in manufacturing and is the backbone of our industries. Robots can automate highly variant, dangerous and exhausting tasks in a high-quality and cost effective way. By increasing productivity at a lower cost, maximum cost efficiency is reached, which is ideal in a business setting.

What should I be looking for when buying automated parts?

There are a number of things to keep in mind when buying automated parts for your warehouse or setup. Below is a basic guide with questions to ask yourself to make the process a little easier.

Is there a warranty? If so, for how long?

Protect your investment on your automated parts. Warranties are important in insuring that your part is functioning as intended and in getting what you paid for. Make sure you check under what instances a warranty can be claimed and how long the warranty lasts. Are there detachable parts within the automated component that are covered? MRO Electric and Supply offers a minimum 12-month warranty on all listed parts.

Is the part compatible with the machinery that is already there?

There are a multitude of environments that certain parts can be more oriented towards, including in aerospace and automotive manufacturing, food processing plants or laboratories. It is essential that the part be used in the correct application to be effective. It is obviously important that the automated component works with the setup already in place. Some additional compatibility questions to ask yourself before buying:

Does the weight or form factor impact its compatibility? Is space an issue?

Many people are eager to buy large parts for their warehouses without considering the space to put them. Consider the part and its intended configuration. Include additional equipment that comes along with the part like peripherals, fencing, light curtains or mat guards.

Will the condition of the part affect its lifespan in this application? Is there a newer, better part for this application?

Check to see if the part is new, used or refurbished, and if the condition will affect its application. Many industrial parts are discontinued as new technologies evolve, and while these legacy parts are still useful, newer components might work more efficiently or effectively. Check to see if there are any advantages or disadvantages to older and newer generations of your part and weigh your options.

How does a relay work?

What is relay?

A relay is an electrically controlled switch that has the ability to turn a circuit on or off. Depending on the application relays can do a number of things. Relays can be used as switches to turn things on and off, or as amplifiers to convert smaller currents into larger ones. They can also be used to control a circuit with a low power signal or when multiple circuits need to be controlled by a single signal.

There are two kinds of relays, electromagnetic and solid state. In this post, we will be focusing on electromagnetic relays and how they work.

Basic Parts of a relay

Armature– is a basic metal piece that is balanced on a pivot or a stand. It is considered the moving ‘arm’ of the relay. It makes or breaks the connection with the contacts connected to it.

Spring– is connected to one end of the armature and pushes the armature back into place if no current is passing through.

Electromagnet– is a metal wire wrapped around a metal core. The wire does not have magnetic property but can be converted into a magnet with the help of an electrical signal.

Yoke– is a small metal piece affixedon a core which attracts and holds the armature when the coil is energized.

Contacts– conductive material that exists within the device whose physical contact opens or closes a circuit

A break refers to the number of locations on a circuit that a switch can make or break the flow of current. In electromechanical relays, there can be single breaks and double breaks. A single break is usually used with low power devices while a double break is usually used with high power devices.

A pole refers to the number of circuits that relays can pass through a switch. A single pole contact carries current through one circuit, while a double can carry it through two.

A throw refers to the number of separate wiring paths. For example, a triple throw switch can be connected to one of three contacts instead of one.

How does it work?

In an electromechanical relay, a small circuit has the ability to switch a larger circuit on or off through contacts by using an electromagnet. When charged, the electromagnet creates a magnetic field that attracts the armature and closes the contacts. Some contacts come in different configurations depending on the use of the relay. A normally open (NO) relay’s contacts are open when there is no current passing through, while a normally closed (NC) relay’s contacts are closed when there is no current passing through.

PLC vs. DCS: What’s the difference?

Before we get into the differences of a PLC’s and DCS’s, we need to talk about what each of them are designed to do.

What is a PLC?

A PLC, or Programmable Logic Controller, is a computer that has been adapted to specifically meet the needs of any specific manufacturing process. These devices come in many different shapes and sizes, with many options for digital and analog I/O, as well as protection from high temperatures, vibration, and electrical noise. The invention of the PLC allowed computers to be streamlined into the industrial automation process.

A PLC can be a single device calculating and executing operations, or a rack of different modules may be used to meet whatever your automation system requires. Some of the additional components include processors, power supplies, additional IO, interfaces, and much more.  Every part works together to be able to run open or closed loop operations that are rated at high speed and high precision. Take a CNC machine for example; a PLC would be used to control positioning and motion, as well as torque control. These devices are popular because they are very inexpensive relative to the amount of power and how many hours you get out of them.

 What is a DCS?

A Distributed Control System is an automated control system that streamlines the functionalities of the various devices that are used throughout an entire work space. This type of system uses many different controllers to allow all the machining parts to talk to each other as well as computers that can input parameters and display information such as power usage, speed, and much more. These controllers are distributed geographically across a plant to allow for high-speed communication to the control room. When using different types of modules however, the system may require different communication standards such as Modbus and Profibus. DCS’s started coming to fruition throughout the 1960’s once the microcomputer was brought widespread into the market.

Then what exactly is the difference?

A PLC will probably be used to control a machine that isn’t too complex wheres the DCS can have total control of all the operations in an entire plant. The PLC is preferred in situations where the machine does not have to worry about meeting specific conditions inside the plant. These conditions typically involve operations that may need to stop or restart, as well maintaining precise temperatures. A DCS will be able to take advantage of all the aspects of an automated system, from the machines and sensors to the controllers and computers. An entire DCS is much more expensive than a few PLC’s, but each have their advantages in any given situation and certain automated systems will always require one over the other.

Kawasaki E3/E7/E9 Controllers

Being a leader of the robotics industry for over 50 years, Kawasaki has developed one of the most complete lines of e-controllers on the market. All of these controllers are suited with a wide array of features including:

  • High powered CPU performence
  • Large, easy to use LCD Display
  • Optimized key layout
  • Easily accessible safety switches

The E76/77 family of controllers are very compact and used for smaller robot arms. One of these arms are the RS003N Robot, which has a maximum payload of 3kg and has horizontal and vertical reaches of 620mm and 967mm, respectively. The controllers with these robots specialize in assembly and material handling applications.

The E9 family of robotic teach pedants are also built very compact, however these devices are typically used in medium-duty applications. Unlike the other two families of controllers, the E9 family features an open structure system with a direct cooling system. However, like the E7 and E3 families, the enclosed structure with indirect cooling is an available option. The E9 family takes full advantage of the digital servo drive powering it to have a maximum payload capacity of 40kg.

E30/32/33/34 controllers at their base are very alike the E76/77 controllers but with more power. These devices are not as compact as the previous devices we have discussed, however the reason being they are highly expandable and are easier to maintain. Features such as Kawasaki’s K-Logic sequencer software allow the addition of up to 16 total controllable axes. The E3 family of Kawasaki e-controllers are able to handle the following maximum payloads:

  • E30 – 145 kg
  • E32 – 180 kg
  • E33 – 195 kg
  • E34 – 180 kg

Looking Inside the Siemens Sinamics CU305, CU310-2, and CU320-2

Electronically coordinated single-motor drives work in unison to perform your all of your drive needs. In multi-axis drives, the individual drives are controlled from a higher-level control system in a way to achieve the desired coordinated movement. A centralized Siemens SINAMICS Control Unit has control over the drives for all connected axes and also establishes the links between the drives and/or axes. Since all required data is stored in the central Control Unit, it does not need to be transferred. The CU310-2 is used in conjunction with power modules and single-motor drives whereas the CU320-2 is used with all motor modules or line modules for both single and multi-motor drives.

Different versions of these control units include:

All of these control units are based on an object-oriented SINAMICS software called SIMOTION. The firmware included contains all common control modes and can be scaled to meet almost all automation requirements. This firmware will contain instructions for infeed controls for main infeeds, and all vector an servo controls.

Looking Inside the Siemens Sinamics SME20/25 and SME10/125 Encoder

The encoder system is connected to the SINAMICS S120 via DRIVE-CLiQ. Motors with DRIVE-CLiQ interfaces are designed for this purpose. These motors simplify commissioning and diagnostics because the motor and encoder type are identified automatically. The Sensor Modules(SME20, SME25, SME120, and SME125) are only to be used with machines and may ONLY be connected to the DRIVE-CLiQ interfaces of proprietary components. Direct encoder systems outside the cabinet can be connected to the Sensor Modules External. The SMEs evaluate these encoder systems and convert the calculated values to DRIVE-CLiQ. No motor or encoder data is stored in the Siemens SMEs. The Sensor Modules External provides the encoder power supply. The power supply for the SME is provided from the connected DRIVE-CLiQ cable. This should be taken into consideration when selecting the DRIVE-CLiQ cable. SMEs have a higher degree of protection(IP67) which means it is suitable to be installed on the outside of the cabinet.

Part numbers for the SMEs include:

Below is a chart that shows the connectable encoder systems between the SMC and SME modules.
