Parameter object
(DFD11B in
MOVIDRIVE
®
B)
• The fieldbus parameters of the MOVIDRIVE
®
B can be addressed directly via the in-
stance with the parameter object.
• In exceptional cases, you can also use the parameter object to access SEW para-
meters.
• Class code: 0F
hex
Class
Instance 1 and 2 of the parameter object offer access to SEW parameters as follows:
• First, the index of the required parameter is set in instance 1.
• Next, instance 2 is used to access the parameter that is addressed in instance 1.
Access to an SEW parameter index via the parameter object is complicated and prone
to errors. Consequently, this process should only be used when the DeviceNet scanner
does not support configuration using the mechanisms of the register object.
