| Until a few years ago the transporter control system was a module which was integrated into the EPCS. Then a significant progress was achieved by the partial decentralisation of this control system into an intelligent system mounted on the transporter. This system is responsible for the so-called emergency manual control and set-up operations. The advantages are clear: |
| |
| - |
No external system for controlling the transporter. |
|
| - |
In case of complete power failure the transporter can be moved by an external power supply (e.g. heavy-duty receptacle). |
| - |
No bus communication, PC control, visualisation etc. necessary for moving the transporter. |
| |
| In the course of these decentralisation efforts the distance measuring system was changed from incremental to absolute distance measuring. The advantages of absolute distance measuring are: |
| |
| - |
No initialisation after power failure |
| - |
No reference runs or reference positions |
| - |
No wrong positioning |
| - |
Completely flexible acceleration and deceleration of the transporter |
