Machine: Maho 1000
Control: Philips 432
A brief background: My client has had this machine for several years. A year ago it was having several control issues. At that time we removed all the power supplies, drives and the Philips rack. We cleaned all the boards, replaced the weak capacitors, curved trace all the IGBT's, cooling fans and fixed cold solder joints, etc... We reinstalled everything and the machine has worked well for the last year.
Now to the discrepancy / question I have: The electrical drawings I have show the input and output cards and the bits that we see on the screen in real time. Currently we are missing the CNC Ready (output card 1, bit 2) There is no 24v output coming from the output card which in turns goes to the relay board #1 Relay 19K1. My question, is there a logic diagram or some other way to find out what is needed in order to satisfy the requirements for this output? (and, or, nor, ladder logic type info) How do you determine what is required, as far as inputs, internal logic etc... in order to get an output to turn on?
I'm including a picture of the circuit mentioned above.
Thank you for any ideas.
