Instance Attribute "AtReference"
This attribute indicates whether the actual value is at the reference value (e.g. the drive actual speed
is the same as what is requested in the speed reference). If the bit is 1, the drive actual value is at
the reference value.
Instance Attribute "NetRef"
When the bit is 1, the torque or speed reference is requested to be allocated to this network
interface. If the bit is 0, then no such request is made.
NOTE! The actual assignment of the reference to this network interface is reflected in the attribute
29 .
d
Instance Attribute "NetProc"
This attribute is used to request torque or speed reference to be local or from network. Values are:
• 0 = Set reference not DN control
• 1 = Set reference at DN control
Instance Attribute "DriveMode"
Allowed values for Drive Mode defined in the following table.
NOTE! The actual drive mode support depends on the used drive and application. Check the actual
drive mode support from the drive application manual.

Changes to DriveMode attribute must be reflected in the "Motor Control Mode Object". The drive will
respond with "Invalid attribute value" status code 0x09, if other values are written.
Instance Attribute "SpeedActual"
This attribute allows reading of the speed actual value. The unit of the attribute must be (RPM /
SpeedScale
2 ), where the SpeedScale is attribute 22
If the SpeedScale attribute is not used by the master, the default unit [1 RPM] is assumed. This is
equivalent to the value 0 being used for the SpeedScale.
