How to wire Leadshin h2-758 Hybrid drivers?

[Youngyaper]

Having some difficulty getting any pulses/dir to the drivers and not sure if im wiring this correctly. Attached is the pdf for the driver. This is a chinese machine and the leads coming from the driver to the original controller were labeled p+, p-, d+, d-, red, black. Im currently using the screw terminals on the acorn (not the db25 since i would have to order one). From the Acorn controller to the driver I have Step to p+, Dir to d+, Enbl+ to red wire, COM to p-, d- and black wire). In CNC12 for the axis settings i have tried some of the defult screw terminal settings but nothing works. Ive looked at some schematics and some have the inverse of how i hooked up the terminals (p+,d+,enabl+ to 5v, and d- to dir-, p- to step)

Could someone recommend any available schematics that could work for these drivers?
is it necessary to use the db25 Break out board instead of the screw terminals?

Thanks for any help.

Hello and welcome to the forums.

You should probably check the drive manual because on page 6 it says that the pulse and direction pins only accept 5 volt signals.
It doesn't look like you wired it in a way that would damage anything. You didn't wire +24V directly to the drive inputs or Acorn screw terminals, correct?


These drivers are best used with the DB25 header because that has 5V line driver outputs and that wiring method will give the best performance. The screw terminals are open collector outputs so they would need a pull up resistor connected to 5V to function.


If you end up using the open collector screw terminal headers, the drive has resistors built in for 5V pull ups. You'd follow the left diagram on the 10th page of the attached manual. Wire the PUL+ and DIR+ signals to the 5V output of the Acorn's power supply. PUL- and DIR- would then go to the STEP and DIR terminals on the Acorn.

Thank you for this information. I wired it the way you said it it works!

Can you help me hook up the inverter aswell?

heres what im trying to figure out. this is the link to inverter details https://www.woodstar.in/product/best-in ... 220v-380v/) originally theres 4 wires coming from the inverter that hooked up to the old controller, coming from the inverters ports labeled COM, x1 and AX1, COM. According to the inverters diagrams, X1 is for forward start, and AX1 is for the 10v analog signal. Ive hooked up the AX1 and Com wires to the acorns VFD OUT and COM port. Ive also connected X1 to the 5v supply, and COM to COM on the acorn. Im Not able to get the spindle running. Any ideas what im doing wrong? Thanks for any help.

Tackle one issue at a time and it's easier. On the vfd remove it from acorn completely and you can use a 9v battery to simulate the 0-10v speed input, and you should be able to touch two wires together to make it run. Once you have the vfd working without acorn, then it's easier. I do these all the time and I still make them work by themselves first.

The inverter supplies its own voltage on the inputs. All you need to do to have the Acorn start it is wire from X1 to an Acorn relay normally open terminal and then from the common terminal of that relay back to the inverter's COM terminal.

I'd recommend finding the manual for the inverter and looking into setting up its relay output as a fault output. Then set up one of the unused inputs to reset/clear the fault codes. A reference schematic for that is S14983.

It works, thank you!

Youre correct, it works now, thank you.
