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...

Hi Mateuse, In that case you might do a dual loop approach. 2 KFLOP Axes will be required for each motor axis. Keep the existing rotary encoder axis and create a new linear encoder position loop which causes the other axis to move. A small C Program is required to tie the two loops together. It take...

Hi Mateuse, It’s best to utilize both the rotary encoders and the linear encoders. For example there may be cases where the motors move which is observed by the rotary encoders but because of backlash or compliance the linear encoders do not observe anything. So the rotary encoders can really help t...

Regarding mechanical relays: they cannot usually be driven by LVTTL signals. What are their specifications and do they have a reverse diode across the coil? Regarding 400V ground. Is this earth ground? It doesn’t normally make sense to connect a noisy earth ground to shields of signal lines. You mig...
