For the PowerFlex 700S drives, the drive's VPL microprocessor must move the buffered data. For more
information, see page 1-7.
Center Node
Explanation:
Master - PowerFlex 700S drives
Slaves - PowerFlex 700S drives
The SynchLink node clocks and the VPL clocks are synchronized
across all nodes.
· Typically, this configuration is used to transfer direct data.
· If you want to pass buffered data, the local controller at
each node must pass the data.
· Data can be passed back to the master node.
Axis data is not supported in the configuration.
