CAC-10 with IDCP-00 - current loops
BUT! I am not sure if this current loops are passive (externally powered) or active (internaly powered). What I found out... for Actual value I am able to change passive/active using IDCP "SUP_OFF" parameters (am I right?).
I have no idea what is the type of SetPoint loop - this is the biggest question mark!
I am going to use 4..20mA for both loops... I already know that I need to put jumper between pin 3 and 4... I don't want to use CAI and CAO only CBC module!

First of all, you need the connection details to the converter you want to control. Without them it is very difficult to guess were to connect your wires.
Then, pins 9 and 10 give the control setpoint(speed?) to your converter. This is in the form of 4-20mA and if you connect with the proper polarity you wont have any problems. In this current loop CAC-10 is "sourcing" the current and the converter side simply "reads" it. This is very simple.
On the other hand, it may not be so easy for the feedback current loop. This is your second 4-20mA loop from which you get the feedback variable (speed, current?) as a portion of current. Depending on how the converter transmitts the current, you have to connect accordingly your card.
The drawing you attached shows a loop powered position feedback of a valve. This means that CAC-10 though pin 11 supplies voltage and then the end device(positioner) regulates the current of the loop at 4-20mA. If your converter's datasheet allows such connection go ahead. But i think that it is most possible that the converter supplies itself the current loop of the feedback, so in this case you must apply a different connection. The plus(+) of the loop shall be connected to pin12 and the minus(-) to a ground(0Volt) pin(pin2 or 9). Everything depends on your converter...
So, check your information and try...
