Musab Posted February 22 Report Share Posted February 22 Hello Everyone, I had problems using V700 - V200-18-E46B. The terms of use and the errors I encountered are as follows: There are 7 contactors 230V AC in the system panel. 4 units of 5.5kW and 3 units of 7.5 kW. 1.jpg; O.S. (Stop Mode - Fatal Error) Enum: 0x00000801 IP: 0x00344704 00344566 Ldr: 0x000000F7 Desc: Illegal Word Operand Access 2.jpg; O.S.

However, this is an undesirable situation as it poses a risk for our production. Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted February 22 MVP 2023 Report Share Posted February 22 I've seen this in the past when the Snap-In module works loose. Be sure it's snapped in tightly and consider a bit of duct tape to hold it tight. This is especially a problem in a high vibration environment.

MVP 2023 Joe Tauser Posted February 22 MVP 2023 Report Share Posted February 22 It could also be caused by transients from the contactor coils working their way into the I/O module backplane. Do you have RC snubbers across the coils? Joe T. Link to comment Share on other sites More sharing options...
