I have recently bought a second hand Hercus PC-200 lathe from ebay which requires new controls (the old controls recommended DOS 3.3 and apparently even then it didn't have the processing power to do accel and decel curves)
I have lurked around here for a while and worked out that i will probably be ok with a Grex running 3 x G320's however what i haven't been able to find is a wiring diagram for the inter-connections, so i have started my own.
Attached is a draft of my intended wiring, the remaining issues i was wondering about was how are the limit switches supposed to be wired and do i need the opto-isolators between the encoder and G-Rex (as i remember reading somewhere)
I have an e'stop on the machine that i will also wire in as well as a pendant but they're for later.
Any comments would be appreciated.
