Dear Friends ,
i wanna to issue new program with CPU 1214DC/DC/DC , SB 1221 5 VDC , 4 Analog output from the wiring of SB 1221 i noticed that all inputs must be connected to - ve voltage is it meaning that i have to connect ( A' , B' ) ( inverting A , Inverting B ) to sb1221 ?? i measured by the multimeter the voltage of A & B signals with the 0 volt , it gives me 3.3 voltage all the time ( with speed and with zero speed ) what is the meaning of that ? if i measure inverting A , it will give me -ve voltage ?
any suggestion ?
