Response time of speed
measurement
Calculation formula:
Response time of speed measurement in ms = 13 +
7500/n
[n] = min
−1
Error response time of
speed measurement
1)
No greater than the response time without error.
1) The fault response time is the total time from when an internal error occurs or an external error in the en-
coder circuit is detected until the safe state triggered by the safety card.
