That is an older Acorn board. Not current generation.
You need to wire a relay board such as this one to its 6 outputs (There are two built on that Acorn):
6 Channel 24VDC Relay Board PLC DIN Rail Mounting NPN

Then wire your VFD to the dry contact relay outputs

Ok, need to oder it first, come back later,and which schematic should i refer,

You are basically adding a relay board. You will feed the relay board with 24VDC. Then you will take the board channel inputs and connect them to the Acorn Outputs. Acorn outputs sink the signal when turning them on.
You have two relays on the Acorn for channel 1 and 2. I recommend you use Channel 1 to control a large estop contactor.

To answer your question, once you wire in the relay board, you should be able to follow the later schematics. (Current)
Why do you have an old revision Acorn?

Probably because he bought it more than a year ago?

Yes, it's true, i brought it more than a year ago,, i just using the small trimmer machines to make as spindle, and control in with swicth, manually on &off,, unfortunately the link that marty gave on ebay, it doesn't make shipment to my country which is malaysia,, is centroid make a shipment outside us in this covid time? And how long its gone a take, i thought to buy a relay from centroid,,

Just source at least a 6 channel NPN opto isolated relay, from wherever. I suggest 5VDC or 24VDC voltage.
You don't have to use the one I sent. You need dry contact outputs if you want to minimize the risk of damaging the Acorn board.

Input: fully compatible with PNP and NPN. Com terminal: connect 0V or 24V. Output: The output voltage is the power supply voltage.
Is that compiled? Or must have relay type, thi one is not have relay on it,, pictur i canot upload,, dont know y,, keep saying server errors, still try to working on it,

Something like this,,

I would recommend dry contact relay outputs.

Founded this, ali baba,
Is this suitable,
