Simodrive E/R Module Fault – Troubleshooting

We had a customer who was getting an alarm on their Simodrive E/R Module with a fault on the machine after the hydraulic was put on. They had tried resetting the machine but the same alarm would come back up. The Simodrive part number was 6SN1145-1BA01-0DA1, the only light on it was the green LED and the terminals were both reading 27VDC. The customer was considering buying a new drive but wanted to check to see if there was some way of resolving the issue without buying a whole new Simodrive.

Based off the LED configuration that the customer was having, we determined that the external enable signal 63 was missing, so they needed to double check their connections. When the customer checked, the contact from the hydraulic connector was not making a good connection. All the customer needed to do was replace the contact kit and restart the machine which got them up and running. We would highly recommend always double checking the connections on a unit before replacing it, because there can often be a simple issue that doesn’t require the full unit to be replaced.

Siemens 6SN1118-0DJ23-0AA0 Control Card – Product Video

Here is a video of one of the Siemens 6SN1118-0DJ23-0AA0 Control Cards that we have in stock. This is a control card for a Siemens Simodrive system, and would be inserted into a Simodrive power module such as a 6SN1123-1AA00-0EA1. We occasionally have people call in to order just the control card or just the power module, not realizing that they are two separate units that are sold separately. When deciding that you have an issue with one of these, make sure you test both the power module and the control card and order accordingly. The control cards can be used in multiple power modules so there is not one particular setup for installing one of these. If you are replacing the control card, you should also test the power module before replacing the control card because you can end up damaging the replacement 6SN1118-0DJ23-0AA0 control card if it is installed in a faulty power module.

The 6SN1118-0DJ23-0AA0 unit in this video has been fully refurbished, retested, and repackaged in our own packaging. We have plenty of all of the different Simodrive control cards in stock, so if you’re looking for a similar unit just give us a call at 800-691-8511 or email for a quote. The individual parts page for this unit is here, hopefully this helps and if you need anything else please let us know.

Modicon 140CPU43412A CPU Product Video

We currently have both new and refurbished 140CPU43412A CPUs in stock, fully tested and ready to ship out same day if need be. This Modicon 140CPU43412A CPU is one of the more popular CPUs in the Quantum Series from Schneider Electric/Modicon.

Just as a side note, we often get questions as to what the differences between Schneider Electric, Modicon, Square D, and Telemecanique are. Modicon, Square D, and Telemecanique were all bought by Schneider Electric over the years and their products are all now manufactured by Schneider. A full history of the Schneider Electric acquisitions is available on Wikipedia here.

Back to the CPU, if you are looking for the general description or the technical specs, here is a link to the PDF listed on Graybar’s website. The predecessor to this CPU is the 140CPU43412, where the 140CPU43412A is functional identicial to the non-“A” version, the only differences being that if you are using multiple units in a hot standby system you need to use either two 140CPU43412 units or two 140CPU43412A units, and the “A” version has a unique flash executive which isn’t interchangeable. We have another blog post detailing the differences here.

Below we have a video of the product itself to help with anyone who is looking for replacement. For pricing or any other questions give us a call a 800-691-8511 or email
