Control a VSD via cDAQ

[emily001]

Good morning,

I need to control 2 electric motors using 2 variable speed drives (ACS580 and ACS880). I have cDAQ 9188.

For the ACS580 I need to control the speed and the direction of rotation for the electric motor. And for the ACS880 I need to control the speed and the torque, and to be able to switch from speed control to torque control and vice verca.

Everything should be controlled via a single program in LabVIEW.

My question is which modules and, if needed additional hardware, will I need? Will it be enough to have one analog output module and one digital output module into the cDAQ? (For now I have NI 9269 analog output module. I also have one NI 9481 relay module. Can I use it somehow for this purpose?)

Thank you in advance.

Hi Emily,

     What control signals do the drivers require?

     Also, would you be using an encoder to read back velocity feedback? Would you also be measuring torque?

 All these questions determine the IOs that you would need/
