Looking through the other Maho & Deckel retrofit threads I see I am not the only one who stays away for extended periods. Hoping to get some info on the gearbox shift mechanics and logic of my FP5NC. Attached is the SPS logic tree for the spindle and gearbox shifters. There are 3 micro-switches on each of the two gear shift motors allowing for LH, Center, RH on the 'Gearbox' selector fork and LH, Neutral, RH on the 'Backgear' selector. The two motors are driven using 3 relays K10 (gearbox), K11 (backgear) and K12 to reverse either motor.
Hopefully one of you native German readers can help interpret the attachments included.
Finally got a motor and VFD operational. Almost have it fully wired up to my FP5 existing PLC etc. Question I have is how was the original FP5 DC drive controlled:
According to the attached print, I assume the run command is the PLC signal:
X50:1 Reglerfreigabe (Hauptspindel Reglerfreigabe)
Google translate gives me: 'main spindle controller enable'
My guess is that speed is set by the -10v to +10v input and then run is commanded by 'Hauptspindel Reglerfreigabe'
I have no way to test this output since my existing DC spindle motor is dead and the system fails out when run is commanded.
It's an interim thing. My intention is to get it running w the existing PLC to reverse engineer the shift sequence before trying to convert to LCNC. The nice thing is that because the system is so modular, I should be able to pull out the PLC (Deckel calls it the SPS) and transplant LinuxCNC in its place.
