Me again. i think the logic for the code was wrong. This seem to work, but need more testing: #define DT 3 double LAST_A; //static double T0; // remember the last time we turned on void disable_machine_overload() { double IPR = KANALOG_CONVERT_ADC_TO_VOLTS(ADC(7)) * 5; // Voltage return from VFD sta...

Hi Tom. Need one more help. I need a non-blocking way to control the maximum spindle amperage and disable the machine if it stays above X value for X time. #define DT 3 double LAST_A; void disable_machine_overload() { double IPR = KANALOG_CONVERT_ADC_TO_VOLTS(ADC(7)) * 5; // Voltage return from VFD ...

Hi Tom. The final code: int adjust_rpm; //outside funcion, global scope void controlspeed() { double IPR = KANALOG_CONVERT_ADC_TO_VOLTS(ADC(7)) * 5; // Voltage return from VFD if (IPR > 10) // if amperage > 10A { SetFROTemp(0.8); // Set feed 80% adjust_rpm = 1; // set variable to confirm feed was mo...

Hi Tom,

the kanalog is reading the "A", amperage from the motor this way:

double IPR = KANALOG_CONVERT_ADC_TO_VOLTS(ADC(7)) * 5;

Can i read the actual feedrate? to return after the adjust?

int actual_feed = "GetFRO()";

if(IPR>15)
{
SetFRO(0.8);
}else
{
SetFRO(actual_feed);
}

Thanks!

Hi all. As I work with wood, the grain variation and wood species varies a lot in final hardness and feed requeriments. My machine has spindle load feedback and i converted it to A. The spindle is capable of 15A max load, but sometimes it can go as high as 19A in some grains. Is there a way to contr...

Hi Tom.

This is what i have from the chinese manufator. The encoder is 24v. The paper shows 5v but it's 24v.

Is there a way to test if kanalog is able to read the return of the encoder?

Hi Tom.
Here is the scheme for the MPG pendant.

Thanks

Hi Tom.

The machine is capable of 45m/min. If 17hz is 4m/min it can do 170hz at 40m/min?

Also, bought a pendant that has a 24v encoder. is there a way to wire it to kanalog ?

If not, i may test with 5v even if it is 24v?

Thanks.

Hi Tom!

The axis pitch is 40mm, 4000 / 40 = 100 rpm. It also has 2 pulleys, 2.5 to 1, 100 * 2,5 = 250rpm.

Is there a way to take away this resonance ?

Thanks!

Hi Tom, As my knowledge in this is limited, I tried different axis tuning, modifying PID to different values while maintaining error small. And all tunings resulted in marks on the finished part. (tried different tools and holders to verify also, with different speeds I got better results. even fast...
