    摘要: The invention is especially useful for inspecting the solder paste pressure on printed circuit boards. The three-dimensional surface structure (19) is optically detected and the values of the geometric characteristics thereof are calculated. The thus measured values are checked for respecting an absolute range of tolerance. An operator can evaluate indicated errors as pseudo errors for fine tuning the limiting values. The measured values are automatically taken as new limiting values of the respective absolute range of tolerance.

    摘要: The invention relates to a method and a device for monitoring a drive, comprising a drive motor (1) which produces a first rotational movement (5) in a first drive shaft (2), and a control device (4) for the drive motor (1). In order to monitor the drive for excessive sluggishness, the speed of the rotational movement is modified substantially according to a predetermined curve (20) by suitably controlling it, thereby effecting a change in direction of the rotational movement. The value of a characteristic variable is determined using the ensuing curve (21) of the torque (M) produced by the drive engine (19), the value is compared with a reference value and a drive error is indicated by way of a signal when the deviation exceeds a predetermined threshold value. The invention allows detection of increased friction without using a complex sensor system.
