Abstract
Provided is a clamp system with enhanced functionality achieved by detecting the behavior of an object to be clamped, using a stroke-end position detector that has been used for switching stroke operations. A clamp devicehas an output memberwhich executes a stroke movement causing a change in the distance by which a coilis inserted into a holehaving a bottom. A converteroutputs a measurement value of the inductance of the coil. The inductance of the coilwhen a work W has been clamped by the output memberis stored in a work clamp point memory, and a clamp area indicating a variation range permitted with respect to a work clamp point is set in a clamp area memory. During processing of the work, a control unitmeasures the inductance of the coil, determines whether the work clamp point is within the range of the clamp area, and, if the range is exceeded, issues a signal indicating an emergency stop.
