Q
Can AD2S1200 be used with "SINCOS" sensor?
A
Yes, if by "SINCOS" sensor you mean a Resolver (resolver is like a
motor/generator with windings at 90 degrees so it gives Sin/Cos outputs).
The converter accepts 3.6Vp-p ±10% input…
Minsaraganesh,
1. In AD2S1200 the external buffer circuitry required for EXC signals which supplies Resolver rotor winding. Will there be any buffer for the stator winding output of resolver which is being connected to SIN and SINLO…
Hello, This AD2S1200 has ADC internal both sin and cos inputs.
As you know, ADC sampling has an aliasing if without low pass filter before input.
Is AD2S1200 also have possible introduce aliasing issue same as other ADC components?
If the answer yes…
I was referring to the link https://www.analog.com/media/en/technical-documentation/application-notes/75731446AN264.pdf and https://www.analog.com/media/en/technical-documentation/data-sheets/AD2S1200.pdf to understand and interpret dynamic characteristics…
如果旋变输出的波形不接AD2S1200,输出的正旋差分信号是完全符合AD2S1200的输入的,直接接示波器波形如下图1:
图1 旋变输出的信号直接接示波器
图2 旋变输出的sin和sinLO接到AD2S1200输入端,再用示波器看波形,波形下端被截止一部分
这是为什么?一直没有找到解决方法,输入AD2S1200的波形符合3.6Vp-p,10HZ
I am using a resolver on a 10 kW motor via the AD2S1200. The DOS and LOT signals indicate a fault after only approximately 10 ms of operation. There is noise being picked up (as seen on the sin, sin_lo, cos, and cos_lo signals) even though screened cables…
