Q64AD scale range 4-20mA

No, you are sending via CC-link right? The signals should not fluctuate, you have an error in your program (probably the sequence of setting Ys)

i Has Found Out Why the figure Cannot receive by VFD Because of the Remote Register (Rww) and (Rwr) is diffrent.. Can pls Explain it? I dont understand Why Does Rwr , 0-3 , 4-7 , 8-12 , 13-16 , 17-20 DEC ? Why Does Rww , 0-3 , 4-7 , 8-B , C-F , 10-13 , 14-17 HEX ?

Because they are two different types of devices. See the printscreen from the manual.

In : actual input (example 12mA 2047.5) InMin : input range min (0mA) = 0 InMax : input range max (20mA) = 4095 Out : actual output (Example VSD 12mA = 4000 ) 40hz OutMin : output range min = 3000 VSD 30hz OutMax : output range max = 5000 VSD 50hz OUT = [(Example 2047.5 - 0) * ( 5000 - 3000 ) / ( 4095 - 0 )] + 3000 = 4000 ? Isit the figure? Or i got it wrong way? Pls teach me Edited by alvis

InMin : input range min (0mA) = 0 InMax : input range max (20mA) = 4000 {4095 means the input signal is out of range} In : actual input (example 12mA 2400) {4000*12mA/20mA=2400} OutMin : output range min = 3000 VSD 30hz OutMax : output range max = 5000 VSD 50hz Out : actual output (Example VSD 12mA = 4200 ) 42hz {[(2400 - 0) * ( 5000 - 3000 ) / ( 4000 - 0 )] + 3000 = 4200} Edited by Inntele
