10 Parameter access via the
service channel
The service channel is used for parameter setting and diagnosis. Transfer via the service
channel is handled bit-by-bit in segments in the MDT and in the DT, and may extend
over several SERCOS cycles for each transferred element. The following tables contain
the list of parameters implemented in the drive (operational data).
NOTE: The functional descriptions of the manufacturer specific parameters
- where not given here - are to be found in the MSD Servo Drive Operation
Manual.
