Hello,we have Dainichi CNC lathe with Fanuc 0TF/0TB control,lost parameters due to dead battery.We still have the original parameters list,so we did "DEL"+"RESET"+"Control On" and reloaded #900 parameters first.After control off and on,we got screen like:
PMC Load Select:
1. Load from I/O.
3. Run.
4. Run without PMC.
If you choose #1,control will keep input forever,(also we don't have PMC tape or disk to load).
If choose #3,CRT shows "PMC not loaded".
If choose #4,then loaded basic parameters but can not load Diagnos 300 and 400 parameters,machine won't get out of E-Stop due to missing PMC.

This machine PMC chips built in memory board on master PCB,no PMC board, Parameter 905.0=1 (PMC-L). Memory board p/n: A16B-1212-021X.All voltage check pins (+-15V,24V,5V) on board checked OK.

We also tried to load P900 and DGN 300/400 together,but DGN 300/400 won't take the input value.From parameters list,the D300 should be decimal format,exp.D300=450000,but CRT always shows binery format,exp.D300=00000000,even the P19.7=1.

Since the machine had been working good before battery dead,
1. what caused the problems?
2. How to load PMC?
3. How to input D300/400 (Timers/Keep relays)?

Any help will be appreciated!!
Thank you for your time.
