The slave of CANopen / DMCNET synchronizes with the master via
SYNC. See as the followings:
M: If the slave needs to synchronize with the master, correct the clock
is a must. This parameter sets the maximum correction value per
time. (Unit: usec)
D: Set the size of deadband (Unite: usec). If the deviation between the
SYNC reaching time and the target value does not exceed the
deadband, correction is no need.
T: SYNC arrival time. The standard value is 500usec but it might be
different from the target value. Thus, the buffer is necessary.
Target value＝400 + 10 x T.
For instance, if T=5, the target value will be 450.
E: If the deviation between SYNC reaching time and the target value is
smaller than the range, it means the synchronization is successful.
