Problem:
Machine stops and message „Pacemaker: Profibus communication error“ is displayed.
Possible Causes & Resolutions:
- Cooling water valve: Wrong type of valve or plug without protective circuit (suppressor). The voltage peaks can cause interferences in the Pacemaker electronics. Always use the original plug and valve type.
- Profibus plug: On the plug of first and last client of profibus system the termination resistant must be set to ON. Otherwise interference may occur.
- Profibus cables: Check the position of the cables in the control unit. If they are close to contactors, high voltage peaks can create interferences.
