InterBus Parameter Descriptions and Data Protocol 5–5
Parameter Access Parameter access is established by object indices and parameter
related sub-indices to be sent via the PCP telegram.
Table 5.E
Parameter attributes
Each parameter is described by an attribute to be read according to
table 5.F. The attribute consists of one word with 2 bytes which are
defined as follows:
High Byte stores the Unit (scaling) according to the table 5.G,
Low Byte stores the parameter number.
Table 5.F
Parameter Access Fault Codes
("Additional Error Codes")
The error messages listed in the table 5.G indicated problems when
attempting to access parameters via PCP.
The drive will NOT fault but indicate to the user that a specific
parameter access failed.
