6.10 Word setting for sent message configuration
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] are used to assign the meaning of configurable words of the sent message; these words can be used to:
Send the signals that can normally be displayed through analogue outputs;
Send bit significant information for identification of any intervened hardware and/or software protections;
Send bit significant information concerning Drive status;
Send bit significant information concerning status of the microprocessor card (BASIS board) digital inputs and outputs;
Send bit significant information concerning status of the DO expansion digital inputs.
All these parameters can be associated to any process data ID, with the limitation that they shall correspond to the word size. For the data
normalisation see paragraph 8.3 of the Programming Manual.
6.11 Management of loss of communication with the PROFINET IO master
In case of loss of communication with the PROFINET IO master, drive control can act 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, that 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 PROFINET IO using the
values received before 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 that 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.
6.11.1 Function for commands/references update delay via PROFINET IO in case of serial tear-off
Parameter Delay Com Restore [81.05] sets a delay in the command/reference update after restoring communication. During such delay the
previously stored commands/references are maintained.
6.12 Command word, status word, alarm word
Command words are used to send commands to the AD3000 drive through the PROFINET IO network; for the meaning of every command word bit
see paragraph 8.4.1 of the Programming Manual.
Status words are used by the control to provide information concerning 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.
6.13 Control parameterisation via PROFINET IO
The drive configuration parameter setting can be implemented via PROFINET IO by using the PKW parameterisation data of messages exchanged
between master and slave (drive). Such data is used by the PROFINET IO 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 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.
