S7 1200 sinusoidal signal

[janardhan26reddy]

can posiible to take RESOLVER output sinusoidal signal feedback to given to plc s7-1200 to control the position of system.....
if is not possible why?.....

plz help me...


thanks for ur help

There is a resolver decoder card you can get for the S7-1200.
There are special chips that are designed to look at the amplitude relationship between TWO sine waves that are 90 degrees out of phase.

HAI PETER,HOW R U?


Having a servomotor inbuilt with resolver instead of ENCODER & then,we can use resolver decoder card to interfacing a s7 1200 plc to take the signal from the resolver sinusoidal (SIN & COS Values) to control the motor....



Thanks

Usually the resolver circuitry on the motor can generate incremental encoder counts for the PLC or motion controller. This is the easy way to interface with the resolver. Another way is for the resolver motor circuitry to generate SSI for absolute positions.

sorry for asking a repeat question.....
Actually RESOLVER generate a sinusoidal waveform naa sir.....& without digital moduler.. how can u interfacing to s7 1200 plc sir......


thanks sir
