24 ODVA TORQUE
SCALE This parameter only applies to the ODVA
AC/DC drive profile. The units of reference and
actual torques for the ODVA AC/DC drive
profile are given by the formula below.
Torque unit = N·m × 2
(-1 × ODVA torque scale)
where:
(N·m = Newton × Meter)
Note: While a wide range of resolutions may be
configured, the actual performance is limited to
the performance capabilities of the drive.
The table below shows the how the drive ODVA
torque scale parameter values correspond to
the ODVA torque scale units.

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, class 91h .
When written via these methods, the new value takes effect after the drive
is repowered or a “Fieldbus Adapter Parameter refresh” is given.
