ABB FENA-11 - Torque Reference (AC;DC Drive Object)

EtherNet/IP – Communication profiles 165
Torque Reference (AC/DC drive object)
This attribute is the torque reference for the drive. The units are
scaled by the Torque Scale attribute of the AC/DC drive object.
See parameter 24 ODVA TORQUE SCALE for details.
The adapter module provides the drive with a torque reference in
percent of the motor nominal torque. The ODVA AC/DC drive
profile uses Newton-meter (N·m) units for the torque reference.
The drive torque reference is calculated as follows:
where
For example, for a 1000 N·m Motor Nominal Torque with a unit of
1 N·m and an ODVA Torque Reference of 500, the drive torque
reference is:
Dtr = Drive Torque Reference in Percent of Motor Nominal Torque
Otr = ODVA Torque Reference
Ut = ODVA Torque Unit (see 24 ODVA TORQUE SCALE on page 126)
