The Attribute Identifier of this attribute is 24 d . This at-tribute allows reading and writing of the torque scaling factor. The TorqueActual and TorqueRefvalues are scaled according to the value of this attribute. The default value is 0d .The largest allowed value for this attribute in the Vacon 100 drive is 7 (allowing resolution of 0.0078Nm) and the minimum allowed value is -8 (allowing resolution of 256 Nm). The maximum torquevalue that can be input/output to the Vacon 100 drive is thus ca 8.4 MNm.Instance Attribute “RefFromNet”The data type of this attribute is BOOL. The Attribute Identifier of this attribute is 29 d . This attributereveals whether the torque or speed reference is local or from the network. If the reference is local,then the value of the attribute shall be 0. If the reference is from the network, then the value of theattribute is 1.6.2.3 Vendor Specific Objects6.2.3.1 Vendor Parameters Object, Class 0xA0The Vendor Parameters Object is a vendor-specific object which allows the user to access anyapplication parameter from the drive.Instance Attribute “Parameter Value”This class has an instance attribute which is named “Parameter Value” and has the AttributeIdentifier 01h.In Vacon 100 Drive option board the attribute ID is 8 bits in length. When accessing a driveparameter, the drive parameter ID high octet is the instance ID of this class, while the low octet isthe attribute ID which is specified. The data type of the parameter value can be 8, 16 or 32 bits.Table 25.Class Name Vendor Parameters ObjectClass Identifier A0 hClass Attributes Id Name Data Type Access Rule- - - -Class Services Id Name- -Instance Attributes Id Name Data Type Access RuleXX h Parameter Value Read-writeInstance Services Id Name0E h Get_Attribute_Single10 h Set_Attribute_SingleTable 26.Drive prm ID high octet Drive prm ID low octetInstance # Attribute #
