Great to hear that you are up and running. Does your board look like mine or the "newer" version with the PWM to analogue chip? If it has the chip then the 0 - 10V should also work as it's using the same code as the NVEM.
 
Hi Scott,

I checked the PWM signal today. Apparently it doesn't work. I connected a 9volt block battery to Gnd and Vso and measured in Com. Everything is displayed correctly in the Hal Show, however, the measured value between Vso and Com does not change. It is constantly at 8.7 volts. Is my measurement method correct?

Your method is not correct.
You must connect 24Volt to the controller Main Power Port and the Output Power Port
Connect an Voltmeter at the COM and VSO of the Spindle port.
Give an command in Linuxcnc to run the Spindle and change the speed with a command. Look at the voltmeter if it changes.

Hi Scott,
I have connected 24 volts to the board and for the IOs. Likewise at the General Output Interface (Pin 1+5). I don't see any voltage on the VSO and Com. Regardless of the speed set in Linuxcnc. 

Did you gave the M3 (Spindle CW) command and de S command in LinuxCNC?
Like S1000 or S750 or.......

You don't have to connect 24 Volt to the general Output. See manual EC500

Iff you have a voltmeter between COM and VSO and you have started the spindle (M3) and then change the rpm of the spindle with the S command the reading of the voltmeter (DC) should change

Hi Scott,
here is a short video of what i did.   photos.app.goo.gl/7iqFXFaowZrbVXis6   (hope it works)

Hello Christian,

Altough its difficult to see on the video, cam out of focus, looks that you give the right commands.

BTW im not Scott. Maybe he has some sugestions.
Will put Remora on my EC500 to see iff its working.

Christian are you Dutch?

Hi the current HAL file example does not have any of the spindle commands linked to Remora outputs or SP values. You will need to test directly using halcommand and set the value of remora.SP.0 directly. And you need to have the full config loaded into the EC500.
