Abstract
A method of producing at least one control signal data look-up table for a mail insertion machine having a 360 degree cycle of operation and capable of variable operating speeds within a given cycle. The mail insertion machine possesses predetermined electro-mechanical lag times for extending and retracting mechanical components. The method entails creating a baseline control signal data look-up table for a first operating speed based upon pre-determined electro-mechanical lag times. The look-up table comprises a start angle and a stop angle within the 360 degree cycle of operation. The start and stop angles are then compensated for a second operating speed based upon the pre-determined electro-mechanical lag times for extending and retracting mechanical components and the first operating speed. A second control signal data look-up table is then created by writing the compensated start and stop angles that correspond to the second operating speed into the second control signal data look-up table. Look-up table data is stored in computer memory. Additional control signal data look-up tables can be instantaneously created upon selection of a different desired operating speed.
