IHSV57 AXBB

[bearr]

I have recently ordered a bulkman3D UltimateBee Kit with UC300 and IHSV57 Servos. I also purchased an AXBB-E controller due to some of the bad reviews about the UC300. I have wired up everything and the servo has a green blinking light it will not move at all. I have wired the servo just like I would a stepper and the only thing I get is green blinking light.

I decided to remove all other wiring and motors and connected only one servo and still can not get anywhere. I got PUL+ wired to O9 and Dir+ wired to O10, the axis is enabled. Negative wire for each is going to -5v. I also tried wiring the ENA+ to O11 and set that in UCCNC and it made no difference.

Any help would be greatly appreciated.

You have that backwards. On the AXBB, the output ports are the ground side. You need to connect O9 to Pul- and O10 to Dir-, and connect +5v to the Pul+ and Dir+ terminals. You can leave Ena+ and Ena- disconnected.

No, Frank, that's not true. Only the O1 to O8 are open collector outputs, the O9 to O17 are pulled up or down, so you can use both 5V0 and 5V+ as common.

The IHSV57 manual does not mention that the power LED is flashing, but I checked some videos and it seems to be normal.

(In the last few days it's the second time I see "that" UC300. It's a nice job, they even used the CNCdrive logo in their manual. Not perfect on all pages, but they tried to do their best.)

Okay, my mistake.

due to some of the bad reviews about the UC300.

This is not CNC Drive's UC300ETH, which is excellent, but a chinese controller with the same name. FYI.

Ahh. That Novosun, Digital Dream, black box thing.
Makes sense now.

I too am getting a Green LED flashing? What does that indicate? Power On but Not Enabled?

Who is supplying +3.5VDC to +24VDC ENABLE signal? I am only measuring 1.5VDC (feeding 24VDC through current limit R2K7 to motor ENA. Why so low?

Thanks, Billy
