Response time of speed measurement

Calculation formula:

Response time of speed measurement in ms = 13 + 7500/n

[n] = min⁻¹

Fault response time of speed measurementThe fault response time is the total time from when an internal error occurs or an external error in the encoder circuit is detected until the safe state is triggered by the safety option.

No greater than the response time without error.

Maximum length of the encoder cable

30 m
