HDBB2 Breakout Board VFD Control

[dominicburke200]

The HDBB2 Breakout board is very good for attaching all the inputs and outputs for my machine but I am having trouble understanding how to control a vfd speed using it.
How is the best way to control a VFD with an analog signal as the breakout board gives 0-5v and the vfd's require 0-10v.

Is there another board required to do this or is it possible to control the vfd using a digital pwm and if so would any of the pins on the breakout board be able to do this.

I have a Yaskawa V1000 and trying to connect it to a Uccnc HDBB2

I have attached the wiring diagram below, If anyone has any experience and would be able to suggest the correct way to wire this together.

Normally, S1 and SC would go to a normally open relay, with an output pin activating the relay.

So If I use a 12v din relay (NO) I can connect the relay output and simply use it as an unpowered switch for the vfd, which I can see would work. I was just hoping there would be a less messy way of doing it. I'm not interested in using s2 for reverse, so that would work fine.

The speed output for the vfd is either looking for a 0-10v input or can I use the rp (pulse train) from the breakout board directly rather than the analog route as the uccnc hdbb2 breakout board only has a 0-5v analog signal.

Not always necessary those inputs are sourcing so any sinking output can do it directly with no relay such as G540 etc http://www.cnczone.com/forums/spindl...equipment.html
If coming from a Printer port a 2n7000 will also do it.
