Ethernet
AC30 series Variable Speed Inverters
PTP Profile
Each PTP device has a set of attributes as define by IEEE1588-2008. On the inverter the default attributes values are set as follows. Note that
some may be modified by a parameter.
Attribute Description Inverter default value Modified by parameter
domainNumber
A domain consists of one or more PTP devices
communicating with each other. Devices on the
same domain will have the same domain number. 0 -
slaveOnly
When slaveOnly is TRUE the PTP device may only
be a slave and not become a master clock.
FALSE
1684 PTP Clock Type
logAnnounceInterval
A port in the MASTER state will periodically transmit
an Announce message.
Announce messages will be transmitted such that the
logarithm to the base 2 of the mean value of the
interval in seconds between message transmissions
is the value of the
logAnnounceInterval .
1
(2 seconds) -
logSyncInterval
A port in the MASTER state will periodically transmit
a Sync message.
Sync messages will be transmitted such that the
logarithm to the base 2 of the mean value of the
interval in seconds between message transmissions
is the value of the
logSyncInterval .
-1
(0.5 seconds) 1681 PTP Log Sync Interval
logMinDelayReqInterval
The logMinDelayReqInterval will specify the
minimum permitted mean time interval between
successive Delay_Req messages.
This value is determined and advertised by a master
clock based on the ability of the master clock to
process the Delay_Req message traffic.
0 -
announceReceiptTimeout
The value of announceReceiptTimeout will specify
the number of announceInterval that has to pass
without receipt of an Announce message
3 -
