Gentleman…   Does Rockwell have any simulation PLC code that mimics an SMC-Flex soft starter?  Since we are using those (as well as the E3+ and E300) I would like to develop a model environment for starting of several drives.  In a specific case, we may have 3 or 4 drives in a pool of drives in which only a subset must be running at any one time.  Development of ladder logic for starting and maintaining those drives running while considering various fault conditions and startup issues would be very helpful in our environment.  I would like to be consistent among various areas within our plant that we incorporate pools of drives, from 4 to 2.  Having the ability to test in the lab would be very beneficial.  Thank you, David

Greetings, We (in the steel industry) have many pumps / motors (large and small).  Generally we use soft-starts,  cross-line starters (E3+) or even Flex drives. There may be several motors in a pool to start where we need only say 2 of 3 to be running at any one time  When it's time to start them, we may need to stagger start them, if one fails, the spare may need to start.  My question to the group is... Are there any philosophies out there (and hopefully pseudo or actual code) as to how to start a subset of motors/pumps within a pool of motors and maintain the configuration running ? I appreciate any and all comments. David
