Wiring multiple closed loop steppers
Lathe setup, I'm replacing the open loop steppers with Closed Loop. StepperOnline motors, using StepperOnline CL57Y drivers. Looking at the schematics in the knowledgebase, I see there's one for setting up a single motor with this driver. I also see there are schematics for setting up multiple closed loop motors (albeit with a slightly different driver), and the wiring is much different - using the DB25 connector instead of the ST1/ST2 connections on the board.
If I have two CL57Y drivers, should I wire them up as follows?
DRIVER 1:
* PUL+ = +24VDC
* PUL- = ST1
* DIR+ = COM
* DIR- = DR1
* MF+ = COM
* MF- = EN1
* ALM+ = IN5
* ALM- = COM
DRIVER 1:
* PUL+ = +24VDC
* PUL- = ST2
* DIR+ = COM
* DIR- = DR2
* MF+ = COM
* MF- = EN2
* ALM+ = IN5 (Piggyback with Driver 1, or does this get its own input?)
* ALM- = COM
...Or do I have to do the wiring up through the DB25? If so, is "MF+/-" on the driver the same as Enable on, say, the CL86T?

Yes. I know that, and I referenced it above. But that doesn't answer my question.cnckeith wrote: ↑Tue Mar 26, 2024 2:38 pm latest schematics are on the schematics page here

what is the question? if you are asking if you should do something different than what the Centroid provided CL57Y schematic shows...then the answer is no.
wire it like the schematic shows.

Re: Wiring multiple closed loop steppers
I'm looking at ACORN_rev4, STEPPERONLINE CL57Y Drive for the single drive, which is the driver I have 2 of.
There's also a multiple drive setup that uses the DB25 connector, but for a slightly different driver (the CL86T): ACORN_rev4, Multiple STEPPERONLINE CL86T Drives
And the single-drive setup for the CL86Y looks the same as the one for the CL57Y I'm using. So my question is: do I need use the multiple-drive CL86T schematic as a reference, or do I hook up my two steppers using ST1/ST2 terminals as I outlined above?

Re: Wiring multiple closed loop steppers
use the CL57Y and just wire up a second motor just like the first. don't use the CL86T schematic that has as that is not your drive.friolator wrote: ↑Tue Mar 26, 2024 2:56 pm I'm looking at ACORN_rev4, STEPPERONLINE CL57Y Drive for the single drive, which is the driver I have 2 of.

Re: Wiring multiple closed loop steppers
I have one of the motors working and I'm hooking up the second to test.
Does the DRIVE OK (ALM+) connection for the Y axis driver piggyback on the Acorn's Input 5 along with the alarm for the Z axis driver, or does it go to a different Acorn input? if the latter, do I then have to to set that up in software?

Re: Wiring multiple closed loop steppers
You can either use one input for multiple drive fault signals using the DriveOk input or wire the individual drive fault signals to different inputs using Axis(1,2,3,4)DriveOk

Re: Wiring multiple closed loop steppers
ok, thanks. So if I put them both on the same terminal the only downside would be that I won't know which motor alarmed if it happens, but if I keep them separate I will?

Re: Wiring multiple closed loop steppers
Those drives should have a LED that will flash with fault code, so that would give you a visual of which one is faulting.
