PC based CNC

Filed under: Uncategorized — Kenn Anderson @ 10:14 pm

Nova Systems is working with a PC based CNC software package. This software runs on a properly configured, PC of your choice.  We suggest using an Intel product as the drivers have been tested with those processors.  Other than that, there are no requirements for special computer hardware.  Depending upon needs, there are CPU to hardware bridges available for bringing in encoders, override pots, etc. This system is perfect for small machine tools and other small automated equipment. Please call Kenn Anderson at 414-771-4800 for more information.

DC Drive Replacement

Filed under: Obsolete Drives,Uncategorized — Tags: , , — novaadmin @ 9:01 pm

Nova Systems recently completed replacing a failed, obsolete DC motor drive on an Aluminum extruder. This drive was connected to an unusually designed DC motor with a series-connected field coil. Nova was able to find a creative solution to control this existing motor with a modern Carotron Blazer DC drive, while replacing a minimum of external components. This minimized expense and down-time to the customer.

We were able to achieve this while only having an incomplete set of schematics, largely not written in English.

If you have an old or obsolete DC motor drive that needs to be updated, Nova Systems can help.

Ultra High Efficiency 500 HP Motor Installed

20160915_123618Nova recently successfully completed a 500 HP motor installation on a turbo fan at a  food processing plant, here in
Wisconsin. The motor was an Ultra High Efficiency, permanent magnet synchronous motor controlled by a Control Techniques M700 drive. This was the largest permanent magnet motor installation done with Control Techniques in this area, if not the Midwest. (more…)

Profinet Interface to ABB Motiflex e180

Filed under: Uncategorized — Tags: , , — novaadmin @ 9:44 pm

The ABB Motiflex e180 is a high quality servo drive for motion control. However, for many customers, the options in networking such an exceptional drive over Profinet have been limited. Interfacing the e180 over Profinet with a gateway is thing of the past. Nova Systems has successfully developed a working Profinet network, interfacing the ABB Motiflex e180 servo drive and a Siemens PLC.

Modicon 984 PLC Systems

Filed under: Legacy PLCs — Tags: , , , — novaadmin @ 9:38 pm

Nova has recently completed a service call on a PLC system which dates back to the mid 1980’s. It is truly a testament to the ruggedness of a piece of electronics to still be working after 30+ years of service on a machine tool. At Nova, we have a Modicon 984 rack and CPU set up to help troubleshoot, modify and test PLC programs and I/O cards. Also, Modicon is still available through the Schneider Electric. There are ways to upgrade to newer models, an economic alternative to throwing everything out and replacing with Brand-X.

If you are having problems with a 984 system, please contact us at 414-771-7800 or webinfo@novasystemsinc.com.

Robotic Arm motor drives

Filed under: Obsolete Drives,Uncategorized — Tags: , , , — novaadmin @ 4:56 pm

Once again, robust mechanics will outlive the electronics. So, does one throw out the old for the new? In many cases, Nova can help renew original equipment. In a recent service project, we replaced obsolete Infranor motor drives with the latest Infranor product. The replacement drives were shipped next day from factory stock. The original equipment dated back to the 1995 era, but the new drives, with the help of Nova engineering, interfaced seamlessly between the existing motors and the existing Adept controller. Three days after receiving the drives, the system was running.

Early Programable Logic Controllers

Filed under: Legacy PLCs — Tags: , , — novaadmin @ 8:30 pm

IMG_20160119_142730While returning from Cleveland where I had a Modicon 984 service call, I was contemplating a comparison between the 1990’s equipment and the 2016 equipment. Physical size bordered on gargantuan compared to the micro controllers of today. Approximately 400 I/O would take up the space of a 2 foot wide by 5 foot high bay. The system used coax to connect the I/O processor with the Remote I/O processor.

It is interesting how the software, with segments and networks, is remarkably similar to the modern IEC 61131 code in terms of what are now called Program Organization Units (POU). What is most remarkable is that this stuff is still running with the help of EBay and automation collectors.

Having trouble with an old PLC?  Most likely, Nova can help.  For details contact Kenn Anderson at 414-771-4800 ext 1116 or email webinfo@novasystemsinc.com.
