Dynomotion Forum

Tom, I really appreciate your time and assistance!! I really love the Dynomotion system! And your responsiveness! So my mistake was not connecting JP33-7 to PS ground. I looked at the KStep connector info but interpreted that if I was using it as a pot simulation I would need to connect the PS groun...

Tom,

I restarted the system, with no program I measured JP33-6 has 3.95V (JP33-5 has measured 5V)
Toggling IO44 to on in the digital IO window the voltage slightly increases to 4.1V.

Thanks,
Jerry

Tom, So I took the spindle out of the picture by feed the analog output to a signal conditioner and no change. Here is the setup with the signal conditioner. Signal Conditioner: 0-5Vdc input and 0-5Vdc output +5V from 5Vdc power supply to JP33-5 JP33-6 to V+ input to signal conditioner 0V from 5Vdc ...

Here is how I have it wired...

Spindle PS +5V to JP33-5
JP33-6 to Spindle Analog +
Spindle PS GND to Analog GND

Any other thoughts?

Thanks,
Jerry

Hello, I cannot figure out why I cannot get a 0-5V output out of the Kstep to run my spindle speed. Here is my setup... Setup: Kflop connected to Kstep and Konnect Connections: +5Vdc from spindle control power supply to JP33 Pin5 (AnalogVcc) JP33 Pin6 (AnalogOut) to spindle control analog input (exp...
