Thresholds can be assigned for one or more parameters in connection with the operation of a surgical device. An ultimate threshold can trigger a desired action including cessation of operations or modification of operations if the ultimate threshold is reached or predicted to be reached. In addition a marginal threshold can trigger a desired action including improving operations such as slowing operations where the value of a parameter is measured to be between the values defined by a marginal threshold and an ultimate threshold. Multiple thresholds based on multiple parameters can be defined further enabling calibrated usage such as slowing operations based on exceeding both a marginal threshold based on number of sterilization cycles and exceeding a marginal threshold based on extent to which current draw exceeds a certain value.
