The inverter can only process the SYNC mechanism in multiples of milliseconds. For
this reason the allowed values for object 0x1006/0
multiples of milliseconds.
E.g.: 0x1006/0 = 4000 = 4 ms
communication cycle period
If the
the time distance between the SYNC messages over the first 11 messages. Please
note, that the monitoring function is deactivated for setting "0". The measurement is
solely for internal uses of the frequency inverter. The time must not change after
the measurement.
The time distance between two consecutive SYNC messages is monitored.
If object 0x1006/0
then a communication error event is triggered whenever the time defined by
0x1006/0 is exceeded by more than 50%.
After SYNC telegram "A", SYNC telegram "B" has to be received latest after the set
SYNC time + 50 %.
If object 0x1006/0
toring function is not active.
