Regarding maximum speed input for each axis in kflop+kanalog board

[AmitKumar171]

Hi tom,

I am using kflop and i want to know the maximum speed (mm Per minute / Inch per minute) input of each axis supported by kflop .

I want to connect a servo motor in analog voltage (+/-10v) velocity control mode connection to KLFOP+KANALOG.with maximum speed i want is 60000 mmpm. with counts / mm is 10000.

Does KLFOP+KANALOG will support 60000mmpm.?

means what is the maximum pulses/sec supported by kflop in each axis channels ?

Waiting for your kind reply.

Hi Amit,

KFLOP encoder inputs accept up to 1 million quadrature counts/second.

I assume 10000 counts/mm is a mistake? 0.1nm ?

Hi tom,

Thanks for your reply.

That 10000counts / mm i am setting in trajectory planner of kmotioncnc and Motor drive as well.

Is that value 1 million quadrature counts/second is per axis channel or combined all 8 channel ?????

Waiting for your kind reply.

Hi Amit,

That 10000counts / mm i am setting in trajectory planner of kmotioncnc and Motor drive as well.

The units in KMotionCNC Trajectory Planner are in inches not mm. So if 10000 counts per inch that would be 393.7 counts per mm, which would be much more reasonable. So the maximum speed would be:

1000000 counts/s / 393.7 counts/mm = 2540 mm/s = 152400 mmpm

Is that value 1 million quadrature counts/second is per axis channel or combined all 8 channel ?????

1 million quadrature counts/second on all 8 encoder inputs simultaneously.

Hi tom,

Thanks for your reply.

I understand what you said. But i am using 2000 counts/mm for each axis.

So what will be the maximum speed that i can achieve using that.

As in your calculation if i use 2000 counts/mm for each axis then

1000000 counts/s / 2000 counts/mm = 500 mm/s = 30000 mmpm

Is my calculation is right????

if not give me calculation for 2000 counts/mm.

Waiting for your kind reply.

[TomKerekes]

That is correct.

But in that case the trajectory Planner should be set to:
2000 counts/mm x 25.4mm/inch = 50800 counts/inch
