The Vendor Parameters Object is a vendor-specific object which allows the user to access any
application parameter from the drive.

Instance Attribute “Parameter Value”
If you want to read the value of a drive parameter, for example ,“Motor control mode” ID600
d
, set the
instance attribute to value 600
d
and the instance number to 1 to the request. The attribute datatype
in request must be 16 bits. If 8 bit data type is used, then the old method (described below) is used.
The old method from OPTCQ option board is also supported. It can be used when the PLC supports
only 8 bit instance attributes. This method is more complex.
In this mode, set the instance number to high octet of the ID, and the instance attribute as low octet
of the ID. For example, if you want to read the value of ID 2291
d
(08F3
h
), the Get_Attribute_Single
service request is targeted at the Vendor Parameters class, instance 08
h
and attribute F3
h
.
