Benefits of Buying Refurbished Industrial Automation Equipment

At MRO Electric and Supply, we offer a wide range of repaired, refurbished and reconditioned automation products for each of our manufacturer lines. We never supply used, untested, second-hand parts. Each of our refurbished parts is fully cleaned, serviced, functionally tested, and upgraded to optimal working order before being made available for sale. We also place each of our reconditioned products in like-new packaging for easy identification, transportation, and storage.

Benefits of Refurbished Automation Products:

1. Availability
For many obsolete and legacy automation product lines, finding new, unused parts can be a challenging task. Oftentimes, searching for unavailable new parts can cause unreasonably long lead times which increases the risk of downtime. MRO Electric stocks a variety of refurbished products with same-day and next-day shipping options, while keeps the risk of downtime to a minimum.

2. Price
Refurbished products tend to be significantly less expensive than new parts. MRO Electric offers many refurbished items for up to 75% less than their new counterparts. This deep discounting allows our customers to stock up on spares while minimizing their costs.

3. Equivalence
Purchasing an exact replacement prevents compatibility issues versus upgrading to a newer component. For some manufacturers, it is better to stick with tried and true systems than risk purchasing a different part that may not function correctly with their process.

4. Reliability
Just because a part has been refurbished does not mean that it won’t last as long as new. Additionally, many of our refurbished parts have seen little or no use throughout their lifetime. We are extremely confident in the reliability of our refurbishment process, and warranty all of our products for a minimum of 12 months.

G Code CNC

G Code

As a generic name for a plain-text language in which CNC machine are able to understand, G-Codes are important to understand in the manufacturing, automation and engineering spaces. You can enter a G-Code manually if you wish, but you do not have to because of the CAD/CAM software’ abilities along with the machine controller.  G-Codes are not necessarily readable by humans, but it’s possible to look through the file and determine what is generally occurring.

In the factory automation space, nobody likes downtime and receiving error codes. While using CNCs (view FANUC CNC parts here), many professionals are faced with G Codes. By definition, a G Code is a computer code language that is used to guide CNC machine devices to perform specific motions. A few examples of specific motions would be:

  • canned cycles
  • work coordinates
  • several repetitive cycles.
G Code: canned cycles-

Also referred to as a fixed cycle, canned cycles are ways to effectively and efficiently perform repetitive CNC machining operations. They automate specific machining functions. A few examples would be pocketing, threading, and drilling. A canned cycle is almost always stored as a pre-program in a machine’s controller. To learn more about canned cycles, check out this article courtesy of zero-divide.net.

G Code: work coordinates-

The G Code coordinate pipeline goes something like this:

  • Unit conversion to metric
  • Convert from relative to absolute and polar to Cartesian: g90g91XYZ()
  • G52, G54, and G92 offsets
  • G51 scaling
  • G68 coordinate rotation

G-Code is the most popular programming language used for programming CNC machinery. Some G words alter the state of the machine so that it changes from cutting straight lines to cutting arcs. Other G words cause the interpretation of numbers as millimeters rather than inches. Some G words set or remove tool length or diameter offsets. Be sure to check out our article covering FANUC CNC Codes here.

MRO Electric and Supply has new and refurbished FANUC CNC parts available. We also offer repair pricing. For more information, please call 800-691-8511 or email sales@mroelectric.com.

Tool Parameters, Feeds, and Speeds

Listed below are some easily-understood G-code commands in which are used for setting the speed, feed, and tool parameters.

F= Feed

The F command’s purpose is to set the feed rate. Keep in mind, the machine operates at the specified speed rate when G1 is used, G1 commands are set to operate at the set F value.

An error is likely to occur if the feed rate (F) isn’t set once before the first G1 call.  Here is an example:

  • G1 F1500 X100 Y100

S= Spindle Speed

The S command’s purpose is to set the spindle speed. The Spindle speed is almost always set in RPMs (revolutions per minute). Here is an example:

  • S10000

T= Tool

The T command’s purpose is paired with M6 in order to display the tool number to be used for cutting the current file. Here is an example:

  • M6 T1

Fanuc Power Supply Alarm Codes – Alpha Series

Recently we had a customer who was working on troubleshooting a FANUC CNC Power Supply alarm that he had on a machine. He was wondering what the different codes stood for, so we wanted to go ahead and list the different alarm codes for this series. These codes apply to power supplies that start with the following prefixes. The “X”s after the H will be numbered, so an example part number is A06B-6087-H130.

A06B-6081-HXXX
A06B-6083-HXXX
A06B-6077-HXXX
A06B-6091-HXXX
A06B-6120-HXXX
A06B-6140-HXXX
A06B-6110-HXXX

Here is a list of the alarm codes for these series of Power Supply Modules.

AL01: The main circuit power module (IPM) has detected am Error (PSM-5.5,-11)
Overcurrent flows into the input of the main circuit (PSM-15 to –30).

AL02: A cooling fan for the control circuit has stopped.

AL03: The Temperature of the main circuit heat sink has risen abnormally.

AL04: In the main circuit the DC voltage (DC Link) has dropped.

AL05: The main circuit capacitor was not recharged within the specified time.

AL06: The Input Power Supply is abnormal (open phase).

AL07: In the main circuit the DC Voltage at the DC link is abnormally high.

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.

What are circuit breakers?

A circuit breaker is a preventative safety device that detects and stops a circuit if the current is insufficient or in excess. These devices help insure the stability of the electric current in our buildings. Unlike fuses, breakers are reusable and can be consistently relied upon to break a circuit to protect us from potential electrical fires.

How do they work?

A breaker is comprised of a few basic components. A switch is connected to an electromagnet that allows electricity to flow from the bottom to the top terminals.

Source:
http://spmphysics.onlinetuition.com.my/2008/06/uses-of-electromagnet-circuit-breaker.html

With current running through the electromagnet, it becomes magnetized. If the current is suddenly increased, the magnet becomes strong enough to pull down a metal lever attached to the switch linkage. By doing so, the contacts are broken and the electricity is powered off.

What’s the difference between certain breakers?

Residential Circuit breakers- Used in common household wiring to protect electrical appliances like refrigerators, washing machines and fans. Electrical panels can also be designed to have one breaker controlling one specific or multiple outlets in a room that shut off when overloaded.

Industrial Circuit breakers- Used with much larger electrical current applications for warehouses, factories, and other large industrial locations. They can be used to insure safety of the plant equipment, lighting, business systems, air conditioning and wiring.

Voltage– Describes the ‘pressure’ of the electricity. The most common voltages of breakers are . Most household voltage is 120V, with larger appliances around 240V.
Amperage– Measures strength of the current in amperes. Common amperages include 15A, 20A, 25A, up to 6000A.
Pole number– Describes the number of completely separate circuits that can be protected by a circuit breaker at the same time. These include single-pole, double-pole, triple-pole and tandem pole breakers.
Installation location/External Design– Breakers can be designed to be indoor or outdoor based on the application. Different enclosures can be made to withstand different weather conditions.
Interrupting Mechanism– Other breaker designs include air circuit, oil circuit, vacuum circuit, MCB, MCCB, GFI, GFCI and AFCI breakers. While these all serve the same purpose of breaking electrical current in the event of unstable electric power consumption, they have different means of interrupting the current.
