Hi Griffin, With Input Mode = NO_INPUT_MODE the Position should be ignored. On Power/Up Default the axes are in Encoder Input mode. The state of the associated quadrature bits may cause a count of 0, 1, -1, or 2. Switching to NO_INPUT_MODE will not automatically zero the position. In some modes Enab...

Hi Griffin, Sorry you are have problems we would like to resolve this. Have any clues what causes the disconnect? When the machine is idle? What Version are you using? What type of PC do you have? What type of network do you have? Direct connection? Is Kogna the DHCP Server? Or do you have a router?...

Its difficult/impossible to adjust analog servos to command exactly zero and remain still. There will always be some offset and noise with analog drives. If you try something might change next month. Especially with torque Drives as any amount of torque will continue to accelerate. I'm not sure why ...

Also in a Kanalog system there isn't any Supply Voltage information. So on the Step Response Screen Plot Command, Position, and Output to see the DAC Output.

Hi, Creeping is normal for analog drives due to any offset. See here . A common cause of runaway when the servo is enabled is positive feedback instead of negative feedback. See FAQ here . If you enable the Axis by pushing "Move" on the Step Response Screen the plot should help understand what is go...

Hi Tim,

Great would love to see a video.

EnableAxisDest(ch, X); will enable the axis and set the current Destination to X. Do you have encoders? If so the encoder Position should also be set to X with ch->Position = X;

i changed from my custom screen to the basic 2 axis lathe. got the tool path but of course the tool is backwards With a custom screen normally the graphics goes to the GViewer on the custom screen. If you want to use the floating GViewer with your custom screen see here . my Y axis hovering tool in...

Hi Griffin, With those options I wouldn't expect any issues, but we might not be considering something. In general with something not executing correctly, or some context not being preserved between time slices, the results would be indeterminate possibly causing a crash or error. The only real way ...

Hi Griffin, I think the main issue with specifying the 6740 silicon is it opens up Software pipelined loops. The SPLOOP instruction. Which is not interruptible. Kogna never disables interrupts to avoid other issues. So I believe your solution of: -mv6740 -target_compatibility_6200 Should be ok if yo...

Hi Mateuse, As far I understand loop tuning will be carried out as normal for rotary encoder as it is now - no change ? Correct Having this C code running my DRO reading will show linear encoder position instead rotary ? Yes. When defining the Coordinate System define the axes for the linear encoder...
