Just wondering if anyone has any knowledge of these please as I'm not getting a reply to my question from the factory.... There's an "alarm" output on the LCDA2575 driver module - does anyone know what this does in terms of function i.e. when it switches, and what is the max voltage it can switch? I have a data sheet which came with the motors, but it makes very little mention of this output.
Thanks

http://www.t2cnc.hu/downloads/Lichua...r%20Manual.pdf suggests the output is simply the C/E of an optocoupler. Without knowledge of the part number of the opto you could make an educated guess based on common devices - most seem to have a Vceo of 60V upwards.
...of course you could always take one apart to check?Last edited by Doddy; 28-09-2019 at 06:28 PM.

I'd probably go for 24VDC and 20mA being a safe limit.
And given it's very likely a Leadshine copy/clone, and having checked some similar Leadshine drives, their usual output is 24VDC but with current limits varying between 20-80mA.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

Something wrong?
I'd guess it'll depend on all what the driver is capable off, and what settings can be changed via software.
Motor/wiring problem (does the drive sense motor wiring issues?), motor following error (there's a parameter for it...).
Have you got a copy of the 'simple commissioning manual' that's mentioned below the parameter table?Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

I don`t know if this will help, it's a link to their product page

Well, by chance I came across this page:
https://www.omc-stepperonline.com/cl...tor-cl57t.html
These drivers seem to be mechanically and electrically identical to the LIchuan parts other than the paint colour, branding and slightly smaller supply voltage range - if anyone has one of these it would be interesting to remove the cover and compare the PCB with the Lichuan part, I have a suspicion that they will be very similar knowing how things happen in China!. And there's a manual full of all sorts of good info you can download, and which has a very interesting typo in the last paragraph of page 5Last edited by Voicecoil; 30-09-2019 at 10:09 PM.

Hi Voicecoil
The cl57t run with up to 8 amps. I think they are made by leadshine. I have 3 on order at the present time. I'll pop one open when they arrive if it's not to difficult and post a photo.
cheers
Andrew by the way if you order these as kits don't forget they come with cables, I didn't notice that and ordered some cables from their Belgian site. Oh well i'm sure i'll find a use for the wire or plugs
