text: <s>[INST] EM Brake option for the PF40 Greetings, I have a customer looking to have a brake motor (c/w Electro-Mechanical brake (EM brake)). The digital inputs on the drive have an option for the EM brake release, however that parameter option is not available on my demo. The firmware on my drive is at version 2 levels. In what firmware did that option become available? Can I flash the firmware up on the drive? I haven't been able to find a way to do this. Thank you,Chris [/INST] Hi Chris, unfortunately PowerFlex 4/40/40P/400 drives are not field flashable by enduser.Please contact Rockwell Automation Technical Support Centre for further information. Anyway the release of the firmware where this option in the Digital Input was added is 3.02...actually the shipping firmware on those drives is 6.01. Hope this helps… - fuzzy logic \\n </s>
