Feed-To-Stop Only
Tolerance is the maximum allowable error in the positioning of a press operation. Tolerance should be set small enough to get acceptable parts but wide enough to avoid production interruptions.
Note: Be careful to set this value within the limits of the machine.
On feed-to-stop machines, the controller can check if the material is within a specified tolerance before activating the press. If the material has not stopped within this tolerance, the controller halts production and displays an error. The controller allows values from 0.0005 inches to 10.0000 inches. The default value for Tolerance is 0.125 inches.
For example, if the tolerance is set at 0.030 inches, upon stopping for a press operation, the target must be equal to the programmed length. plus or minus 0.030”, before the press can cycle.
