DickDV,
You have made me feel smart. Okay, maybe not too smart. The reason is I know that you are very good when it comes to motors and drives. I can count the number of drives I've messed with on two hands. I have already done exactly what you have said except mess with the decel timing.
I went back to work the day after the original post and thought about this situation, "transfer crashing". I got a little more info on what it crashes into. See, it depends on where a part falls off. It could get jammed between something that has a little "give" to it, or it can jam on something that's very solid. This concerns me with reaction time going through the driver. Just my thoughts though. I also thought that it would be good to monitor the transfer at all times, FWD, REV, and slow down points. Reason is, if sometime down the road leaves a wrench or something in its path, then I'm back to having damaged parts. This gets me dirty looks, because I was supposed to have this taken care of. Anybody been through that? So my thoughts are to protect the whole cycle.
I also found out that the Hakko touch screen on the machine will read, write and monitor a FR-E500 inverter. This might still be a problem with reaction time in the occurrence of a crash. I would probably have to have two monitoring points, one for accel,decel and one for the in-between. I again, think that I will have the reaction time problem, but I'm going to try.
Dick, if you think that the reaction time will not be a problem or overtime as the motor deteriorates I'm not having to adjust the high limits then I'll be sold to the idea. Do you think that the concerns I have in reaction time might be better off by putting a torque limiter with a tripped LS between the motor and the worm shaft?
Thanks, beerchug
