Hello Friends;
I am working on a GE Funac LM 90-30 software. I face the problem to set the CV value when PID in auto mode. The parameters are set as under
1.Enable,Override,Manual,UP,Dn are OFF
2.Sample Period 0.01 sec.
3. Dead Band + and - are 00003
4. Error Term=sp-pv
5.Derivative Action = ERROR (Error/PV)
6. Biase=00000
7.Min Slew Time=00000
8. Upper Clamp=32000
9. Lower Clamp=00000
10. Output Polarity= POS
11. KP=11.18%/%
12. KD=0.00 sec
13. KI= 0.055 rep/sec of 32000
CV value is 22000 even when sp and PV are almost same.
I want that CV will become between 10000 to 14000
Please help me how i fix it?
The other point is My PID loop starts from %R01099 and i use the
BIT SET WORD AND CLR as follows
%R01111=IN of BIT SET WORD use when engine speed cross the 60%
LEN 000001
Const=00005
Same parameters are used for BIT CLR WORD when any shutdown HAPPEN TO THE MACHINE
According to my knowledge it is Anti Wind RESET of the config word of PID.
Please help me
Thanks
