Profinet Interface to ABB Motiflex e180

Filed under: Communications,Drives — 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 — 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.

Some Goodman Rotary cutters were supplied with Baldor Flex Drives. Those drives are now obsolete. Nova has designed a retrofit using the new ABB Motoflex e180 motion control drive.

For a retrofit of Goodman or other knife drives, contact us at 414-771-4800 or webinfo@novasystemsinc.com.

Vacuum Thermoformers

Filed under: Thermoformers — Tags: , , , , , , — novaadmin @ 6:42 pm

The latest thermoformer retrofit done by Nova uses an ABB AC500 Programmable Automation Controller. With this equipment, the user can download and save recipes from a SQL database located on a remote server.  An EtherCAT bus provides communications to 3 servo drives using CoDeSys motion libraries. The machine visualization pages are viewed in a browser connected to the onboard web server.

For more info, contact Nova Systems at 414-771-4800 or webinfo@novasystemsinc.com.

Thermoformer Index Drives

Filed under: Obsolete Drives,Thermoformers — Tags: , , , , , — novaadmin @ 1:03 pm

Nova Systems has a solution for an obsolete thermoformer chain index drive. Once popular Baldor/Sweo drives can now be upgraded with the next generation ABB (ABB acquired Baldor) servo drives. The existing SMCC motion card can be reused, as can the existing servo motor.

For additional information contact Kenn Anderson at 414-771-4800 ext 1116 or webinfo@novasystemsinc.com.

Thermoformer

Filed under: Thermoformers — Tags: , , , — novaadmin @ 10:35 pm

Many manufacturers of vacuum thermoforming equipment used Veeder-Root counters to control the motion and timing of the index, the form press, the trim press and the stacker. These Veeder-Root counters have been obsolete for some time and are getting harder to find in the surplus market. Nova Systems has successfully engineered a machine upgrade to eliminate the Veeder-Root counter.
