Hi Ja_Ja,
I have the same Motion Card but a different VFD. I have just finished playing with this.....
You say you are using the diagram on page 59 but your wiring is not the same as that diagram.
Your 'Pull Up' Resistor ( 1k ohm ) must be wired at the VFD as shown in the diagram.
This gives you an approximation of a 0 -10V signal. The AKZ250 can ONLY output a PWM signal.
The result will 'in the ball park' and can be tweaked by adjusting the VFD input signal parameters.
Make sure your VFD IS actually outputting 10.0V. If its high, no amount of parameter tweaking will fix it.
My VFD outputs 13v ( supposed to be 12V ) so I used a 10v voltage regulator.
You should be able to get within 10% error.
You also don't need the REV signal wire. There is no need to spin in reverse.
