TNC 640 – Running of NC programs Dynamic Precision
Dynamic Precision – High production rates of precisely machined workpieces
CTC (Cross Talk Compensation) prevents errors caused
by acceleration forces.
AVD (Active Vibration Damping) reduces machine
vibrations
PAC (Position Adaptive Control) always offers the
- ptimum controller setting irrespective of the position in
the working space
LAC (Load Adaptive Control) permits adjusting the
controller settings depending on the workpiece weight

Cycle 239 determines the loading weight for a quick adaption of LAC (Option 143)
LAC optimize feed forward and controller parameter
dependent on the loading weight continuously
Cycle 239: Reset parameters to enable safe controlling of
critical axes independently on the loading weight
Determines the loading weight and adapt LAC for a
volatile variation of it Benefits
Very easy to use for the operator OEM configures the cycle process No adaption in the PLC is necessary
