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
EK8Z/AK8Z	5500	6000

INFORMATION

Exceeding the overspeed limit results in a fault message in the safety option with the fault response "STO" within 13 ms for the EI7C FS built-in encoder or 17 ms for safety encoders with MOVILINK^® DDI. 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/17 ms).
