Preventing the mechanical limit speed from being exceeded

To prevent the mechanical limit speed of the encoder from being exceeded, the following overspeed limits are monitored by the MOVISAFE® CS..A safety options.

Encoder type

Overspeed limit

min-1

Mechanical limit speed of the encoder

min-1

EI7C FS

3800

5700

INFORMATION

Exceeding the overspeed limit results in a fault message in the safety option with the fault response "STO" within 13 ms for the built-in encoder EI7C FS. The fault response is executed by the STO circuit within another 2 ms.
Measures in the application must ensure that the mechanical limit speed is not reached during this time (13 ms).
