9 Parameter data transfer
Parameter data are transmitted via the fieldbus as so-called SDOs (Service Data Objects). The SDO
services provide for the write and read access to the object directory.
The SDO channel provides for access to Communication objects (object directory)
( 78) and Lenze
codes with the CoE protocol.
If the "CiA402" technology application is used in the inverter, all CANopen CiA402 objects
implemented can be accessed. (See documentation on the "CiA402" technology application in the
reference manual/online help for the Servo Drive 9400.)
The transmission of parameter data is usually not time-critical.
Parameter data are, for instance, operating parameters, motor data, diagnostic information.
9.1 Establishing a connection between master and slave
Basically a master can always request parameter jobs from a slave if the slave is at least in the "Pre-
operational" state.
