Parameter data transfer
[12-8] Parameter data transfer via the available parameter data channels
Parameters are values stored in codes on Lenze controllers.
Two parameter data channels are available for parameter setting, enabling the simultaneous
connection of different devices for configuration purposes.
Parameter data are transmitted via the system bus as SDOs (Service Data Objects) and
acknowledged by the receiver. The SDO enables read and write access to all device parameters and
to the CANopen object directory integrated in the device. Indices (e.g. 0x1000) ensure access to
device parameters and functions included in the object directory. To transfer SDOs, the information
contained in the user data must comply with the CAN SDO protocol.
Note!
In the Lenze setting, only the parameter data channel 1 is activated according to
CANopen.
• In
, set "2 SDO Lenze" to activate both parameter data channels.
