Parameter Management
(Original Document)
General
The parameters of an axis control module and those of servodrives are managed separately via Control Expert and UniLink. For example, it is possible to define the different values for limits in an axis control module and servodrives.
The parameters of an axis control module may be divided into 2 categories:
NOTE: Servodrives that operate with a linear type unit are not supported by the module TSX CSY 84/164.
Axis Control Module Parameters
Type "C" (Controller) parameters are exchanged whilst floating, in the axis control module units. These parameters are related to the path calculation or cam profiles. They are configured in Control Expert configuration screens, then modified by the application as required. The units of these parameters are the command axis module units as defined in the configuration screens.
Servodrive Parameters
When the application modifies a parameter in the axis control module, the corresponding parameter in the servodrives is not updated (e.g. the minimum and maximum position limits, minimum and maximum acceleration, maximum speed, debugging window).
These parameters are considered to be servodrive system parameters. The user configures them via UniLink in order to protect the operational part and it is not necessary to change them when operating (the application program modifies the equivalent "C" type parameters in the command axis module).
Parameters used by the Axis Control module and the Servodrives
The axis control module does not update the servodrive parameters according to these equivalent parameter values.
Type "S" parameters (identifiers (IDN) SERCOS® Standard) and type "P" parameters (identifiers (IDN) SERCOS® Owner) are exchanged whilst floating with the axis control module and in full with the servodrives (e.g. acceleration, speed and position values).
If the application requires the value of the axis control module parameters to be synchronized with the servodrive parameters, it can read "S" or "P" type parameters (TRF_RECIPE) and then write them in the "C" type parameters (WRITE_PARAM).
"Unit" Parameters
Units are parameters used both by the axis control module and the servodrives.
Units are configured using Control Expert. The conversion of axis control module units into servodrive units is automatically performed by the module TSX XSY 84/164 using a scale factor configured by the user.
