11 ODVA TORQUE
SCALE
Defines the torque scale in the ODVA AC/DC
drive profile. Units of reference and actual
torques for the ODVA AC/DC drive profile are
given by the formula below. No effect on the
ABB Drives profiles.
Note: While a wide range of resolutions may be
configured, the actual performance is limited to
the performance capabilities of the drive.
(N·m = Newton x Meter)
Torque unit = N·m x 2
(-1 X ODVA torque scale)

1)
Use the ODVA torque scale value when reading/writing parameter ODVA
TORQUE SCALE via AC/DC-drive object, class 2Ah. When written via the
AC/DC drive object, the new value takes effect immediately.
2)
Use the torque scale value of the drive parameter when reading/writing
parameter ODVA TORQUE SCALE via the drive control panel, Drive
parameter object, Class 90h and Fieldbus configuration object 91h. When
written via these methods, the new value takes effect after the drive is
repowered or a “Fieldbus Adapter Parameter refresh” is given.
