wiring NI-DAQ to Inverter for monitroing signal proces control Motor induction

[Achmad T.]

ok, in a case i try to control speed of motor AC using inverter, after that i
want to see signal processing from my inverter through data acquisition NI-DAQ
6008, and then in a labview i can use PID and fuzzy logic toll kit for control
my signal and compare that. 



my problem is how to connect and wiring my inverter to
NI-DAQ 6008 ?  i use analog I/O, i also attach wiring installation from
my inverter include control terminal.. i have connected my inverter with my
motor, but i confuse to connect and wiring from my inverter to NI-DAQ. i just
doubt to connect it can i just thorugh connect analog output (AOV) inverter to analog input NI-DAQ>, and after that i connect ouput NI-daq to analog input (AI1) inverter? 

i will be very grateful if you could inform me about wiring and connect from my
inverter to NI-daq and which pins should i connect it to see the signal
processing.

type of inverter that i used is Altivar 31 0.5 Hp/0,37 Kw

Thanks, Regards

Hello Achmad,

In reference to your question on the pin out connections from your Inverter to your 6008 I would recommend connecting the following pins (grouped by task type) based on your previous statements:

AITask

Com -> GND (PIN 1 6008)

AOV -> AI0 (PIN 2 6008)

AOTask

(PIN 13 6008) GND -> COM

(PIN 14 6008) AO0 -> AI1

* Note for the AOTask the input configuration should be RSE with these pins. Additionally, you may have to input a setpoint to your inverter device, but the documentation was not clear enough for me to comment further on the setpoint configuration for your device.

hmm... OK. thank you for suggestion and reply. I would try it...

 maybe I think I would put potentiometer to input a setpoint my inverter device. but in wiring document my inverter i need a power supply 10 V for setpoint potentiometer.

hmm can I tunning set point my inverter device through LABVIEW ?

Hi Achmad,

It's unclear to me if your device requires an external power supply voltage to create a setpoint, or if the inverter itself is generating a 10V ref and requires a variable impedance (potentiometer) to route a setpoint voltage to AI2. If you are unsure as to which is the case, you could use a multimeter to check the voltage on the 10V line. Additionally, if you had a user manual that explained your device functionality a little further I might be able to clarify more in regards to the setpoint.
