    Power PMAC Etherlite and Power Brick AC

    Thank you for the advice.

     

    Good question ;-) It is a test bench to show that pBrick AC can do the job the company want for bigger motors (Gemini Observatory). So I must do it with small motors first.

     

    Another question: The documentation about the watchdog for pBrick AC is quite obscure. It is written 5 Pin TB, is there a N/P from Phoenix Contact or Delta-Tau order?

    Hi,

     

    I am thinking of the power supply about the Main Power Bus.

    There is a procedure for choosing the correct fuses in the manual (p42). The example given if for a AC motor, mine are DC, with a current of 1.6A at 6V, how should I choose the fuse?

    I have another beginner question. How can I know the characteristic of the power supply knowing the motors I will use?

     

    Thank you again,

    Yes it is, thank you very much.

     

    I cannot find any information about the needed optical fiber. Is there a pdf document that I missed ?

     

    EDIT : Ok, I just check the new manuals and it is clearly written. I assume it is SC for all devices. If I have only two devices connected each other, is a duplex possible to use ?

    Hi,

     

    I am studying the Power PMAC Etherlite and Power Brick AC. I would like to link them together using MACRO, is the fiber inside the package ? If not I can't find the information about where one can find it.

     

    I have also some (maybe really debutant) questions:

    - We need a 24 VDC supply quite often, if we use only one for all the requirements (Brake Power, STO and for the Etherlite), do you have some advice on one specific generator supply to do so?

    - What is the +24 VDC RET?

    - Do one need to order all the connectors from Phoenix?

    - Is there any website on which we can order all the D-sub needed?

     

    I would like to use an encoder and the output signal is square signals but this is not digital. Should I use a ADC and then the Encoder X1 or can I use the analog input ?

     

    Thank you in advance,
