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.
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).
Encoder type | Overspeed limit min-1 | Mechanical limit speed of the encoder min-1 |
|---|---|---|
