4.2.1 Object Description of the Drive Parameters
The drive parameters of the MOVIDRIVE
®
drive inverter are described in detail in the SEW
MOVIDRIVE
®
Parameter List documentation. In addition to the parameter index, i.e. the number
with which you can address the appropriate parameter via the communications interfaces of the
drive inverter, you will find further information about the coding, range of values and meaning of
the parameter data.
The drive parameters up to index 9999 can be addressed directly via the FMS services READ and
WRITE. All other parameters such as IPOS variables and programs, for example, can only be
addressed via the MOVILINK
®
parameter channel. The object description in the object list is identi-
cal for all drive parameters. Even parameters that can only be read are given the attribute Read All/
Write All in the object list, as the drive inverter itself carries out the appropriate testing and if nec-
essary supplies a return code. Table 4 shows the object descriptions of all drive parameters.

1 process output
data word (1 PO)
1) Only FMS mode: Transfer of a process output data word from the master to the drive inverter
with the FMS service Write.
2) In the mixed mode (DP/FMS): Reading a process output data word specified by the DP master
(e.g. for visualization) with the FMS service Read.
8289
2 process output
data words (2 PO)
1) Only FMS mode: Transfer of two process output data words from the master to the drive inver-
ter with the FMS service Write.
2) In mixed mode (DP/FMS): Reading of two process output data words specified by the DP
master (e.g. for visualization) with the FMS service Read.
8290
3 process output
data words (3 PO)
1) Only FMS mode: Transfer of three process output data words from the master to the drive
inverter with the FMS service Write.
2) In mixed mode (DP/FMS): Reading of three process output data words specified by the DP
master (e.g. for visualization) with the FMS service Read.
8291
1 process input data
word (1 PI)
Reading of one process input data word (PD 1) with the FMS service Read.
8292
2 process input data
words (2 PI)
Reading of two process input data word (PD 1, PD 2) with FMS service Read.
8293
3 process input data
words (3 PI)
