Pokeys57CNC with AMB 1050 FME-1 DI
AlexRu:
Hello,
has somebody running Pokeys57CNC with an AMB (Kress) 1050 FME-1 DI (digital interface) with the 0-10V Output?
The AMB needs +24V, 0V and 0-10V. There is no dedicated GNDi for the 0-10V. 24V and 0-10V uses the same GND. Pokeys57CNC only offers isolated GNDi for the 0-10V. How can I connect the AMB to Pokeys57CNC?
I tried to connect GNDi to machine GND, but then I always get arround 5,6V, even when analog out is not activated.
Do I have to connect it to another PWM out with a small circuit to generate the 0-10V with the same GND?
Thanks
Alex

I tried to set PIN 20 to PWM and give OemDRO 817 (Spindle Speed) as PWM out, but I only get 3,3 V and no PWM signal from mach3. When I use the Pokeys application, then I can set PWM and I can see the PWM signal with my oscilloscope.
Is there a problem within the mach3 plugin, so that PWM out is not working?
I build a small circuit with a LM358 to generate the 10V, but when PWM is not working, this is not possible.
AlexRu:
Solution was, to add a dedicated power supply for the AMB with no connection to the machine electric. Then it works with the isolated 0-10V output.
Now all is working fine.

I am pleased you have it sorted and thanks for posting the solution.

Hello,
could you explain how did you wired the AMB spindle to the pokeys57cnc?
i can't contol spindle speed
many thanks
Vincent
