5.5.3. Clock synchronisation

Clock-synchro

nous operation is activated by a tick on “SynchronizeDP-Slave at equidistant DP-cycle“.


Time Ti marks the time before the equidistant bus clock (Global Control Message, GC) where the encoder is
sensing the position data with micro-second precision. It should be aimed at the smallest possible value.
250 µs minimum is admissible if encoder operation is without scaling, i.e. always with the maximum
resolution. For enabled scaling the minimum value is 375µs. In case several clock-synchronous DP-slaves
exist in the bus that require more time for data evaluation automatically the maximum value will be utilized.

Time To is insignificant to the encoder. Usually the projecting software makes a proposal under consideration
of correlations to other bus parameters.
