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.
