Huanyang GT Inverter Question about outputs

[TTalma]

I received my new to me spindle and VFD. I am planning to wire it up today. I have a question about the outputs. (VFD manual: http://www.hy-electrical.com/BF/GT%2...s%20manual.PDF)

On page 12 are the connection pins. I want to wire up 3 outputs, Spindle at speed, spindle stopped, and fault. I have an ATC spindle.

On page 50 it states, "There are 2 multi-function relay output terminals, 1 HDO terminal and 2 multi-function analog output terminals in GT series inverters." This implies that there are 5 outputs 2 digital, one programmable and 2 analog.

But looking further down the page it only describes setting up one relay output, and setting up HDO as a digital output. So that is only 2 digital outputs. Looking at the wiring diagram on page 13 it shows the relay outputs wired together, indicating that there really is only one relay output not 2 as stated on page 50.

What am I missing? is it possible to set up 3 outputs? and how?

There are only 2 digital outputs. HDO and Relay.

I see one relay, with both NO and NC terminals.
1 digital output (HDO)
2 analog outputs.

Looks like you could assign the relay and HDO to values 4 and 7, which are fault and zero speed.

Then use the analog out for running frequency. Your control would need to read that and compare it to the commanded frequency?

From what I see HDO is a analogue value only? 4 = Rated Voltage and 7 = output torque.
It would seem you are limited to the one relay output on this VFD version., as opposed the one shown in your related post.

Correction, it does seem that the HDO is digital selectable..

Ok so it is what I thought. I will have to look into the analog as the "at speed". I am using a warp9 ESS (https://warp9td.com/index.php/documentation/doc-ess), with Mach 4. Everything is disconnected. But IIRC the ESS does have an analog input for speed and this works with Mach 4. That would be great to have speed feedback on the PC as well.
