Hello. I'd like some help to generate DC voltage to control an electric motor using a NI PXI-6221 M Series Multifunction DAQ and an SCB-68 Connector Block. I'm plugging one wire of the motor to "AO GND" and another to "AO 0". In LabVIEW 2017, using DAQ Assistant, I go to Generate Signals > Analog Output > Voltage > Channel ao0 > Generation Mode: Continuous Samples. Using Simulate Signal VI, I generate a DC Signal, offset 5 (let's say I want +5 V). Both are inside a while loop. That doesn't work. But when I plug one wire to "AO GND" and another to the constant "+5 V" pin of the connector block, it works. I think there's a problem with the generation of the signal in "AO 0". Could someone help me?
