is the sum of the individual forces applied to each jaw at distance P
The maximum allowed finger length applies until nominal operating pressure is achieved. At higher pressures, the finger length must be reduced proportionally to the nominal operating pressure.
is defined as the distribution of the final position over 100 consecutive cycles.
Controlled via digital I/O.
Weight of the object
The calculation basis is for force fitting with a static friction coefficient of 0.1 and a safety factor of 2 against object sliding due to gravitational acceleration g. For shape fitting or grip holding, significantly higher permissible weights of the object are allowed.
Closing and opening times
are purely the times when the basic jaws or fingers are in motion. Valve switching times, hose times, or PLC reaction times are not included and should be considered when calculating cycle times.
