oh ok, yes now they are on position mode, so i was wonder what happen if switch to velocity, but i understand now, velocity mode would need analog signal like 0-10v+ right? and step and dir always would be for position.

thanks Tom

Hi Tom. I am tuning my 3 axis ac servo motors. what would be the best performance?, position mode or speed mode to select in the drives? the machine is a cnc router, my servo system is using differential line drivers for step and direction quadrature signals and differential receivers to close the l...

Hi Tom

question about the Konnect outputs, in the case i connect directly 24v electro valves or solenoids, do i have to add a flywheel diode? I know some relay card have already flywheel diodes installed but maybe not the solenoids or electro valves.

oh ok, yes it is working ok, when i move the slider up and down the console prints all values right away. now what i noted is the output 26 in aux1 is unchecked, the first time i checked manually to observe the status, but after turn kflop off and turned back on, it appear unchecked, so o i need to ...

I set the VAR to 1, and console print the S value now.

Is the SSO set to 1?

where is this parameter? i attached the log file after ran two g code programs with different spindle speeds, one is 10,000 and the other 18,000 rpm and it printed ok.

I set on tool setup settings the S as "execut/wait/sync" The SpindlePWM.C, the bit 26 box is checked and the state box blinks, so does it mean that the output is working as PWM? now i am trying to figure it out how to set the spindlePWM C values, i entered in the MDI "S3000" and console printed " Sp...

Thank you Tom. I moved the Konnects borards to JP4 and modified the init C program "AddKonnect_Aux0" . You might copy our KStep/KNozz PWM to analog circuit IsolatedPWMtoAnalog.png i have built this circuit already, i am trying to find out how to configure an output as PWM from JP6, do i need a C pro...

Hi Tom

where i can get PWM signal output from Kflop if JP6 is connected to Konnect expansion boards? can i get PWM from one of the IOs of the expansion boards? to control my spindle speed.

regards

Thank you very much. next project i will consider Kogna. have a nice day
