Parameter data transfer
9 Parameter data transfer
[9-1] 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) via the
system bus (CANopen) and are 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. Indexes (e.g. 0x1000) enable 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.
