using analog input as feedback in position following

[odoardo]

HI,

With Power Brick AC I want use different external analog signals as servofeedback in order to implement position following in different mode. 

If I acquire two analog signals in :

 

ADC1 of connector X9.

ADC1 of connector X10.

 

is right do this?

 

PTR ADC1X9 ->S.IO:$900028.16.16;

PTR ADC1X10->S.IO:$900128.16.16;

 

1- Configuring two ECT entry for the two different analog signal

-----------------------------------

EncTable[41].pEnc = ADC1X9;

.

.

.

. 

------------------------------------

------------------------------------

EncTable[42].pEnc = ADC1X10;

.

.

.

.

------------------------------------

 

2- To change analog servo feedback change only this command (using "pmatch")

 

Motor[9].pMasterEnc = EncTable[41].a

pmatch

Motor[9].pMasterEnc = EncTable[42].a 

 

 

In power brick Ac user manual at page 58 is written:

 

EncTable[41].pEnc = PowerBrick[0].Chan[0].AdcAmp[2].a;

 

But the device in this way how can distinguish between ADC1X9 and ADC1X10??

Thanks for the reply.

They are enumerated in this order:

X9 ADC1 PowerBrick[0].Chan[0].AdcAmp[2]

X9 ADC2 PowerBrick[0].Chan[1].AdcAmp[2]

X10 ADC1 PowerBrick[0].Chan[2].AdcAmp[2]

X10 ADC2 PowerBrick[0].Chan[3].AdcAmp[2]

X11 ADC1 PowerBrick[1].Chan[0].AdcAmp[2]

X11 ADC2 PowerBrick[1].Chan[1].AdcAmp[2]

X12 ADC1 PowerBrick[1].Chan[2].AdcAmp[2]

X12 ADC2 PowerBrick[1].Chan[3].AdcAmp[2]
