Object 0x2F31: Last SYNC time
This object is used with the internal microsecond counter of the drive, sampled at the last
SYNC. It is useful when one drive is used to synchronize the entire network. To use this
object for synchronization:
1. Broadcast a SYNC (object 80H).
2. Read this object from one drive (can be mapped to a TPDO).
3. Transmit the accepted value in a Time Stamp object (object 100H).
