Position control process for adjustable clamping elements involves detecting actual position of element by optical measuring device for comparison with intended position

摘要

The position control process for adjustable clamping elements (3) positioned by a setting device (1) involves detecting the actual position of the element by means of an optical measuring device (5) for comparison with its intended position in an evaluation device (6) reporting a correction value to the control or regulating device (8). The control device makes the adjustment, taking the correction value into account.
