Manufacturer objects (0x3000 … 0x5FFF)
In addition to the device profile objects the following manufacturer specific objects
are implemented.

DS301 does not include an object for monitoring the jittering of the SYNC message.
ACTIVE CUBE inverters monitor SYNC message jittering with object 0x3000/0
SYNC
Jitter (given in multiples of micro seconds).
If the SYNC message is received outside the time defined by:
+/-
0x3000/0
SYNC Jitter
a communication error event is triggered.
The value for object 0x3000/0
SYNC Jitter depends on the CANopen
®
master's capa-
bility for time accuracy. The value range is 0 … 17.000 (μs) and is in addition internal-
ly restricted to 50% of the
communication cycle period (object
measured value).
If object 0x3000/0
SYNC Jitter is set to 0, there is no monitoring of the SYNC mes-
sage time.
If object 0x3000/0
SYNC Jitter is set to ≠ 0 then monitoring of the SYNC message
time is active. The jitter monitoring is independent of how the communication cycle
period is determined (either set with object
