AC30 series Variable Speed Inverters
Parameter Name No. Path Default Range Units Writable
PTP Priority2 1686 Setup::Communications::PTP
Parameters::Base Comms::PTP 128 0 to
255
ALWAYS
PTP parameter.
Sets the Priority 2 used as part of the process in determining which PTP device becomes the master clock. See description in
section
Advanced Configuration for more details.
PTP Lock Threshold 1685 Setup::Communications::PTP
Parameters::Base Comms::PTP 0.5 us 0.1 us to
100 us
us ALWAYS
PTP parameter.
Sets the Lock Threshold when the inverter is a slave clock. When the average offset between the slave clock and the master clock
falls below the Lock Threshold then the slave clock is deemed to be synchronised as indicated by the parameter 1688 PTP Locked.
Note that it will take longer for a slave clock to be deemed synchronised when a smaller threshold is set.
PTP State 1689 Monitor::Communications::PTP
Parameters::Base Comms::PTP NONE 0:NONE
1:INITIALISNG
2:FAULTY
3:DISABLED
4:LISTENING
5:PRE-MASTER
6:MASTER
7:PASSIVE
8:UNCALIBRATED
9:SLAVE
NEVER
PTP parameter.
A diagnostic parameter indicating the state of the internal PTP state machine.
Enumerated values:
0: NONE - the PTP module is disabled or the Ethernet cables are removed
1: INITIALISNG - the PTP is initialising the data sets and communications
2: FAULTY - the PTP module failed to initialise
3: DISABLED - the PTP will not send any messages and will accept only PTP management messages
4: LISTENING - the PTP is listening for Announce messages from a master or waiting to timeout on received announce
messages.
5: PRE-MASTER - the PTP behaves as though it were in the MASTER state but will not send any messages except for
peer delay, signalling or management messages.
