With its effect the filter displaces the set speed threshold V

upwards by the amount
delta_v_filter
. For the application one must consider the new response time values
(Treact = Tfilter), as well as the speed at shut-down by PSCBR resulting from this.
6.4 Response times when using PSCBR-E-31-12DI-10DIO
The cycle time of the PSCBR system serves as basis for calculating the response times. In
operation this is
T_cycle = 8 ms
. The specified response times comply with the corresponding
maximum running time for the actual application within the PSCBR module. Depending on the
application, further, application dependent response times of the sensors and actuators used
must be added, in order to obtain the total running time.
