Basic information about the drive system
13.13 Emergency operating mode for DRIVE-CLiQ components
Reconfigurations which must be linked to the DRIVE-CLiQ slave with message "Timing
change" are
● Changes to the DRIVE-CLiQ clock cycle for the component.
● Changes to oversampling settings which require internal reconfiguration of the time-slice
system.
Please also note the following:
● Changes to component connections and longer cables between components require
adjustments to signal propagation delays and therefore also change the timing.
