I have a few questions relating to the SMC04 High power motor controller. I am currently running 4 if these controllers with my own software. I Keep having lock up problems with the SMC04 controllers. My software is delaying 2 seconds at power up and then begins to send a series of 8 - 5 byte Hires packets to the controllers in sequence. Each packet represents a unique controller address. I chose $01-$08 as the addresses. I have the system running fairly well but keep getting crashes during operation. I have taken all of the normal measures to assure that noisy power sources are not the issue. I have kept the baud rate down to 9600 and have played with about every delay between packets I can think of.
Do you have any good examples that show how to best service these controllers in a multi unit buss in hires mode?
I also wondered if schematics are available for this board so as to have a better understanding of what I am looking at when the lock up tale place.
And finally once the controllers start to flash a failure is there any way to clear the error via the serial buss? In my application I cannot run a reset line to all of the controllers.
Thank you in advance.
