7.10 Words configuration setting to configure sent message
The parameters OPZ03 Sel [81.31], OPZ04 Sel [81.32], OPZ05 Sel [81.33], OPZ06 Sel [81.34], OPZ07 Sel [81.35], OPZ08 Sel [81.36], OPZ09
Sel [81.37] OPZ10 Sel [81.38] assign the meaning to the configurable words of the sent message; these words can be used to:
Send signals that normally can be visualised via analogue outputs;
Send bit significant information to identify tripped hardware and/or software protections;
Send bit significant information about the drive status;
Send bit significant information about the microprocessor board digital I/O;
Send bit significant information about the DO expansion board digital inputs.
Each one of these parameters can be associated to any data process ID, with the limitation that they must correspond to the word size. For the data
normalisation see paragraph 8.3 of the Programming Manual.
7.11 EtherNet/IP master communication loss management
In case of loss of communication with the EtherNet/IP master, the drive control can operate with different modes established through the Timeout
[81.03], Freeze En [81.04] and Delay Com Restore [81.05] parameters.
The Timeout [81.03] parameter is used to set the waiting time to restore communication with the master; it is possible to set a value between 0.01 s.
and 10 s. The default value is 0.01 s.
In case of loss of communication with the master, when the timeout expires an alarm is generated and the alarm behaviour is defined by the Fieldbus
Error [36.49] parameter; for the management of this alarm refer to paragraph 12.3 of the Programming Manual.
During the waiting time for restoring communication, it is possible to freeze the reference and Command Word 1 received via EtherNet/IP by using the
values received before the loss of communication; this can be achieved by setting the Freeze En [81.04] parameter to On.
The Fieldbus Cycle Timeout [81.39] parameter sets the limit time of communication loss after which the control considers the communication no
more active and the freeze is activated, if enabled.
Once the freeze has been enabled, it intervenes based on the status of bit 10 of Command Word 1. If the latter is ON, the Command Word 1 and
reference are considered to be valid; if the latter is OFF, the Command Word 1 and reference are not considered to be valid and the valid ones
previously stored are used.
7.11.1 Function for commands/references update delay via EtherNet/IP in case of serial tear-off
The Delay Com Restore [81.05] parameter sets a delay in command/reference update after restoring communication. During such delay the
previously stored commands/references are maintained.
7.12 Command word, status word, alarm word
Command words are used to send commands to the AD3000 drive through the EtherNet/IP network; for the meaning of each command word bit see
paragraph 8.4.1 of the Programming Manual.
Status words are used by the control to provide information concerning the drive status; for the type of information transmitted and the meaning of the
relevant logic states see paragraph 8.4.2 of the Programming Manual.
Through the alarm status words the control provides information concerning drive alarm status; for the decoding of the alarm words bits see paragraph
8.4.3 of the Programming Manual.
7.13 Control parameterisation via EtherNet/IP
The drive configuration parameter setting can be implemented via EtherNet/IP using the PKW parameterisation data of messages exchanged between
master and slave (drive). Such data is used by the EtherNet/IP master to transmit or receive slave configuration parameter values; through PKW data
the chosen parameterisation is automatically stored.
PKW parameterisation data is supported only with PPO1, PPO2 and PPO5 type messages; each one of them has 4 PKW data available both in the
message sent by the master to the slave and in the message sent by the slave to the master.
