Parameters ...
ƒ are values which are stored under codes in Lenze controllers.
ƒ are, for instance, used for one−off plant settings or a change of material in a
machine.
ƒ are transferred with low priority.
Parameter data are transmitted via the system bus as SDOs (Service Data Objects) and
acknowledged by the receiver. The SDOs enable read and write access to the object
directory.
In the Lenze setting, one parameter data channel is available for parameter setting.
A second parameter data channel can be activated via code C1865/1 / C2365/1 or the
implemented CANopen object I−1201 in order to enable the simultaneous connection of
various devices. The parameter data channel 2 is deactivated as default.
) Note!
When the second parameter data channel is activated the possible number of
bus nodes is reduced.
