ABB Microflex Servo and OAK connections <<Answered>>
Posted: Sun Nov 12, 2017 5:18 pm
I’m working on cables to connect my OAK to a couple of 3A ABB Microflex servo controllers. Looking at the cable pinouts for the Oak-Yaskawa Sigma V, and the Oak-Delta servo cables, it appears that pin 19 [faultin] is sourcing, and that pin 21[enable] and pin 22[drive reset] are sinking. Based on that, here is what I’ve come up with for the Microflex controllers:
Oak Axis Connector
The encoder input is straight forward:
And I think I figured out the fault, enable, drive reset, and analog velocity connections. As I mentioned above it looks like fault input was sourcing so I connected that to drive status+ and connected drive status- to Oak signal ground. Enable seemed to be sinking so that was connected to Drive Enable- and Drive Enable+ was connected to Oak +24V. Drive reset appeared to be another sinking output so that was connected to DIN0-, and Oak +24V connected to DIN0+. Digital Input 0 will be configured to RESETINPUT on the Microflex.
Finally, I assumed that Analog Request on the Oak was single ended and connected it to the Microflex Analog input accordingly.
Could one of the engineers at Centroid give this a quick glance and see if my assumptions were correct? I've attached the relevant pages from the Microflex manual for reference. I'd appreciate the sanity check before I connect the drives and possible let the magic smoke out of the drives and/or the Oak!
Thanks,
Tom
