Writing and Reading a
Parameter
Data Status
Language Selection
All data block elements can be read via an appropriate master
communication interface or serial interface. Only the operating data can
also be written.
The operating data of a parameter can be permanently write-protected or
always resp. temporarily be written. This write access depends on
• the communication phase
- and -
• the activation of a password.
Note:
When reading and writing the operating data, error messages
can occur (see "Errors" in chapter "System Overview").
Each parameter has a data status. It contains information on:
• validity/invalidity of the operating data (parameter value)
• status of commands (command acknowledgment) for parameters
used for activating commands (see "Commands" in chapter "System
Overview")
The controller checks the data status of the parameters for validity of the
operating data when changing from parameter mode to operating mode.
Therefor, the operating data (parameter values) of the parameters listed
in
• S-0-0018, IDN list of operating data for communication phase 2
• S-0-0019, IDN list of operating data for communication phase 3
are checked for validity.
The control master can query the IDNs of the parameters with invalid
operating data (parameter values) via:
• S-0-0021, IDN list of invalid operating data for communication
phase 2
• S-0-0022, IDN list of invalid operating data for communication
phase 3
The data status is signaled when the control master carries out a write
command to the data block element no. 1 of a parameter. This allows the
control master to recognize the status of a command started.
See also "Command Processing" in chapter "Master Communication"
In parameter S-0-0265, Language selection it is possible to set the
language in which parameter names and text in units of parameter values
will be displayed.
Notes on Commissioning
During the drive-internal check of parameter values carried out when
changing from parameter mode to operating mode, the following
command errors can be signaled:
• C0101 Invalid parameters (see S-0-0021)
• C0102 Limit error in parameter (S-0-0021)
- or -
• C0201 Invalid parameters (->S-0-0022)
• C0202 Parameter limit error (->S-0-0022)
• C0203 Parameter calculation error (->S-0-0022)
