ABB Microflex Servo and OAK connections

Post by tblough » 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

Code: Select all

PIN	FUNCTION	MICROFLEX CONN/PIN	MICROFLEX FUNCTION
1	Z		X7/3			CHZ+
2	/Z		X7/8			CHZ-
3	B		X7/2			CHB+
4	/B		X7/7			CHB-
5	A		X7/1			CHA+
6	/A		X7/6			CHA-
7	LOGIC GND	X7/5			DGND
8	LOGIC GND		
9	A POS REQ		
10	/A POS REQ		
11	B		
12	POS REQ		
13	/B POS REQ		
14	POS ERR CLR		
15	/POS ERR CLR		
16	N/C		
17	24 GND		
18	BRAKE REQ		
19	FAULT IN	X3/3			STATUS+
20	24 GND		X3/2			STATUS-
21	ENABLE		X3/6			DRIVE ENABLE-
22	DRIVE RESET	X3/4			DIN0-
23	+24VDC		X3/5,7			DIN0+, DRIVE ENABLE+  TIED TOGETHER AT X3
24	LOGIC GND	X3/12,14		AIO-, AGND   TIED TOGETHER AT X3
25	LOGIC GND		
26	AN REQ		X3/13			AIN+
27	LOGIC GND		
28	AN IN		
29	N/C		
30	CHASSIS					SHIELDS CONNECTED AT MICROFLEX END
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

The Oak Fault input must be pulled to 24 GND. It is sourcing (+24V comes out of it), so it must be connected to a sinking output (to pull to 24 GND).

On figure 24 of the "Drive status output" page, pin 23 should go the the fault input, and pin 2 to 24 GND. From the figure, there is no reason that the output could not be wired to pull down instead of up.

Eng199 -

I believe that is what I have on my connection diagram

Code: Select all

19	FAULT IN	X3/3			STATUS+
20	24 GND		X3/2			STATUS-

Hmmm... It looks as if I answered while still asleep. Yes, you had it correct all along.
