Parameter data transfer via available parameter data channels
Parameters are values stored in codes on Lenze controllers.
Ten separate parameter data channels are available for parameter setting, enabling the
simultaneous connection of several devices for configuration.
Parameter data are transmitted via the system bus (CANopen) as SDOs ("Service Data
Objects") and acknowledged by the receiver. The SDO enables read and write access to the
object directory. Indexes (e.g.
) 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.
