  • Adding external encoder to reduce backlash of linear track

    Skyfire, Colinb83 Sorry for the delay in reply. Was in "Quarantine" due to Covid.

    All system axes will be working in sync. Continuous calculations for the positioning can be prone to error. I will stick with better mechanicals.

    Skyfire can you elaborate on
    "Simply avoiding any reversals, or applying anti-backlash motions to keep the preload of the gearing constantly biased in a consistent direction, gives great improvements for minimal investment."

    Thanks and Regards.

  • Adding external encoder to reduce backlash of linear track

    Hello,

    I have a KR16 cybertech with an external axis configured to a linear track.

    Controller: KRC4, KSS:8.6. Application: Welding

    The external axis is mathematically coupled axis.

    I have added additional encoder / resolver to linear track. The 7th axis has to follow this external encoder / resolver for better positioning. Helping me compensate mechanical backlash. The position correction should work in both jogging and program execution.

    Went through RSI and ConveyorTech but unable to find a proper modus of implementation.

    Can we control positioning of a synchronized external axis via additional encoders / resolvers?

    Many Thanks!!

  • $POS_INT showing value with track and reference to World system

    Hello,

    Controller: KRC4

    KSS: 8.5.6

    I want to tap in the touch sense position in to a variable. The system has two external axis: E1: Positoner and Linear track: E2. I am generating an interrupt when touch sensor goes high and recording $POS_INT. But it gives me values with reference to World + track shift. The value shown with respected selected base and tool are not being saved. I tried following variable: $POS_ACT, $POS_ACT_MES. In display --> variable it shows the values with respect to selected Tool & Base but saves a different value.

    Thanks.
