Abstract
The invention concerns a drive for closing devices, for example gates or shutters, with variable speed output drive and a device for detecting a given position of the closing device. According to the invention, the drive speed output depends on the position of the gate and can be controlled depending on the given mechanical closing characteristic of the closing device.
Claims26
A drive system for a closing device having
- a variable speed output drive,
- a device for detecting position of the closing device,
- means for controlling drive speed output depending upon the position of the closing device,
- means for controlling the drive speed output based upon given mechanical closing characteristic of the closing device, and
- an incremental or absolute path detection device for detecting and reporting the position of the closing device and connected with said controlling means, wherein
- said controlling means comprise memory, in which values of the mechanical closing characteristics of a variety of closing devices are stored.
