S200-VTS errors | 01 Feb 2022 | |

S200-VTS errors

We have been using the s200 controllers for years. Model S20360 -VTS.

Now we received a batch that is reporting errors when using in the same application with the same setup file.  Due to supply issues, we had to use a different vendor to procure these devices. 

The error we are getting is “Motor I-I or I-n Short”.

We can connect other boxes in the same unit, using the same settings file, same motor, same cables, they work properly. Our vendor suggests to ask questions here to see if you could help.

Looking at the controllers that are giving issues, we can see the control board through the vent of the box is different than ones we used in the past.  There is a chip in a socket labeled 2.1.  The boxes we were receiving in the past were Xilinx spartan based controllers and there is no FW chip like this that we can see.

Also, can you also tell from the serial number how old these boxes are?  Example, 06K 00254

I see many reference Control Logic 3.0 or higher.  Does the marking of 2.1 on this chip inside indicate these boxes are not 3.0 or higher?

06 = 2006. K = November.

Consider, if the drive is not damaged (especially the capacitors) following the process below:
1. Get a Variac/ variable transformer. Go SLOW. 20V increments?
2. Your part number ALSO obtains its control power from the AC supply. The control logic MAY act strange as the voltage is increased.
3. Our re-forming process MAY NOT have ever expected the drives to never have been energized for a period of 15 years. Go slow if you can, and follow this process.
4. ANYTHING that may fail: Contact G&G Technical and have us repair the drives in Radford, VA at the factory. After a repair, like during initial production, the drives will be run underload overnight. We call this “burn in”. We run and automatically test each drive UNDER LOAD for a period of time.

The above is similiar to what we recommend BEFORE powering up old drives that have NOT been in service for a long time, such as the link below for OTHER drives:

The drives you have can be repaired by Kollmorgen under an RMA, obtained from your local Kollmorgen distributor.

DouglasS,

There are three generations of S200 drives.
HW Rev A used Xilinx Spartan IIe chips, had a labeled one time programmed PROM, and used up to 2.xx versions. We stopped making these in about late 2006.
HW Rev B uses Xilinx Spartan 3 chips, unlabled FLASH chip that allows updating in the field, and used only 3.xx version which the latest is 3.2M. Shipped from 2006 into 2022
HW Rev C uses Xilinx Spartan 3 chips, unlabled FLASH chip that allows updating in the field, and uses only 4.xx versions. Shipping started December 2021.

A date code of 06K means a unit shipped from the factory in 2006 10th month. So, that unit is quite old.

For further help, I suggest contacting our application engineers in Radford, VA via our number listed on our Web site.
