How to solving PIDAT inactive using CP1E-N30S1DR & CP1W-MAD444..?

7 posts in this topic

Dear All, 

I am new for OMRON and my project is need to control VSD on PID function and I using Omron CP1E-N30S1DR connected CP1W-MAD44 (AI/AO is 0-12000) for AI/AO.. 

My programming did followed PIDAT instruction.. and MV output still inactive.. I am not really sure that my programming is correct or not..? Could every one help me to check my program in attached .. please 

I using D400 as SV & PID parameter , D500 as MV.. and I do not move D500 to analog output word yet coz D500 still inactive.. 

Looking for every one reply ASAP..

If you have PID parameter you don't need to SETB bit 15 of D409 to on because if you on it that mean you use auto-tune function.

Hi Wasan,

One more question.. When PV = SV.. why MV is in lower output range..? and i set bit3 of C+5 = 1.. it mean when PV = SV , MV will be 50% of output range..

It likes you drive a car when your car speed arrive at target speed you still press your accelerator to still have target speed not to off it immediately.

Yes when you set bit 3 of C+5 to 1 Output will be at 50 %.
