摘要:
A drive roller, driven by a motor, moves a material web on a set of rollers. The present rotational speed of the motor is detected. A current web speed is determined from the detected rotational speed and a diameter of the drive roller. The current web speed is compared with a specified target speed value and a specified threshold speed value of the web speed.
摘要:
A method for controlling a drive having at least one converter, at least one motor and an assigned drive control, wherein a failsafe CPU is operated separately from the drive control and only processes safety-relevant information, where a number of safety functions are implemented by the failsafe CPU such that the safety-relevant functions of the drive are implemented in a simple and reliable manner.

摘要:
A method detects parameters of a traversing or circulating material web in a material processing machine. At least one oscillation parameter of at least one transverse oscillation which occurs on the material web is detected contactlessly by at least one sensor. At least one parameter of the material web which results from said oscillation parameter is determined. Furthermore, a device detects parameters of a traversing or circulating material web in a material processing machine.
