Siemens Micromaster 420: Troubleshooting Faults and Alarms

A blog we posted earlier this week about the Micromaster 420 troubleshooting referenced the Faults and Alarms list for the Micromaster series, so we decided that it would make sense to make the list of Micromaster 420 Faults and Alarms directly available. This is from the corresponding manual for the Micromaster 420 series, but it is buried within the manual which most people most likely don’t even have. Hopefully, this helps with your troubleshooting of Siemens drive fault codes and alarms.

Be sure to also check out our list of Siemens Micromaster 440 fault codes and our article touching on Siemens Simodrive E/R Module Fault Troubleshooting, along with other Siemens series coverage.

About Sinamics S120 CU320 Modules

There are two Sinamics S120 CU320 Modules. There is the CU320-2 DP, which is the 6SL3040-1MA00-0AA0, and the CU320-2 PN, which is the 6SL3040-1MA01-0AA0.

These multi-drive Control Units increase axis count and functionality. They have an Ethernet port, as well as more I/O and controller to controller communication. Each unit can manage up to 6 servo or vector axes in a high performance system. For standard systems, up to 12 V/Hz axes can be controlled from one CU320-2 unit. These Control Units significantly reduce system costs, as they increase functionality for positioning, safety integration, and drive control allowing all these functions to be controlled by one unit versus several.

Siemens CU320 control units also provide additional flexibility with a high number of programming options and digital inputs. With up to 12 binary inputs, the modules’ high I/O count add ease of use. The additional Ethernet port expands programming options as well. Overall, the CU320-2 control units allow for simple yet flexible performance with minimal cost and space requirements.

Keeping Your Breaker Running

Saif Afridi Leave a comment

In any industry of the modern era, the use of electronics is absolutely crucial and unavoidable. Whether you are operating a CNC shop, process plant, or assembly line, electronics devices and automation technologies are at work there.

Automation is understandably the backbone of our industries. However, it comes with an additional responsibility of maintenance and inspection. This is something industrialists sometimes neglect and core electronic equipment goes unchecked for long periods of time, which can lead to serious problems and financial loss.

In this blog, we focus on one basic electric device: the circuit breaker, and why do you need to keep it in tip-top condition.

Circuit breakers are installed at nearly every point in your plant’s electric layout and offer protection against over-current incidents which can damage sensitive devices like motors, drivers etc. They work by cutting off power supply to the circuit they are connected against if a high amount of current is detected.

siemens breakers

Proper maintenance of circuit breakers is an essentially that everyone must understand. If your breaker is faulty due to poor maintenance, you can end up with a burden that is far more than that of performing maintenance. The replacement of damaged devices in addition to the possible shutdown of an industrial process is not something what we want.

In our opinion, the best way to optimize breaker maintenance is to have a complete system in place. Discussed below are a few suggestions we have for people who wish to keep their breakers in proper running.

  1. Know Your Breaker

Circuit breakers come in different types and ratings. Usually in industries, they are categorized by the voltage they are supposed to handle, short-circuit current capacity (AIC value), and the medium they utilize.

You must know the sort of circuit breaker you are dealing with since each type has its own guidelines and precautions. This makes it much easier to narrow down your maintenance procedures and scheduling.

  • Never Forget the Instruction Manual

Once you have the basic know-how about the kinds of equipment you are dealing with, you should get your hands on their instruction manuals. It is always good to have a product manual at hand when testing out your breaker since it carries detailed guidelines about what procedure you should follow in order to ensure comprehensive maintenance.

  • Develop a Schedule

A maintenance schedule is a must if you want your breakers to be ready for a current overload. Usually the manufacturer advises the time period after which a breaker should be examined, a general thumb rule is that breakers should be tested every 6 months to avoid any breakdowns.

  • Avoid Negligence

This is where most almost everybody falls a bit short. If a breaker is tested and a fault is found, it should not be neglected and be rectified immediately. One should not put off the task of replacing damaged parts. You never know when your circuit might short out and be the cause of harm for your equipment.

In a recent blog post, we discussed the reasons why you should keep your machinery up to date. There are many important benefits to make sure your machinery is in its best condition, but none other than saving time and money down the road. It’s impossible to consistently run any machine and not encounter an issue sooner or later.

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

Brian Hughes Leave a comment

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.
