Explanation
The analog filter only affects the safe analog inputs of
the SMX-12 A module.
Response times of the analog input filters in relation
to the input frequency
Note:
*) : When using an average filter the response time of this filter must also be added
10.4 Response time for FAST_CHANNEL
FAST_CHANNEL describes a characteristic of SMX to respond quicker to speed
requirements than this would be possible with the execution of the safety programs in normal
cycle (= 8 msec). The sensing time of FAST_CHANNEL is 2 msec.
The following response times can be specified:
Notes:
• 6 msec (Worst Case Condition)
• When using FAST_CHANNEL you should bear in mind that shutting down within the
time specified above for a given speed threshold is only possible, if the sensor
information has a sufficient resolution. The smallest resolvable switching threshold of
the FAST_CHANNEL requires at least 2 edge changes on the corresponding sensor
system within a period of 2 msec.
• This function can only be used in connection with semi-conductor outputs.
