Response of an already activated
monitoring function

PLC editing in case of position and
speed processing via safety relays

*)
With a monitoring function that has already been
activated via ENABLE, the module requires one cycle
to calculate the current speed value. During the next
cycle after calculation of the monitoring function the
information is further processed and output by the
PLC, i.e. according to the implemented logic this will
lead to e.g. switching of an output.

only effects the monitoring function in connection with
position / speed / acceleration, but not the logic

The analog filter only affects the safe analog inputs of
the PSCBR-12A module.

6.2 Response time for FAST_CHANNEL
FAST_CHANNEL describes a characteristic of PSCBR 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:
4 msec (Worst Case Condition)
Safety note:
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.
