Drive configuration

Speed Unit = RPM X 2

(-1 X ODVA Speed Scale Value)

Table 6. ODVA Speed Scaling

Use “ODVA Speed Scale Value” when reading/writing ODVA

Speed Scale via the AC/DC Drive Object (2Ah). When written via

AC/DC Drive Object, the new value takes effect immediately.

Use “Drive Parameter Speed Scale Value” when reading/writing

ODVA Speed Scale via Drive Panel, Drive Parameter Object (90h)

and Drive 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.

11 ODVA TORQUE SCALE

This parameter only applies when using the ODVA AC/DC Drive

Profile. Units of reference and actual torques for ODVA AC/DC

Drive profiles are given by the formula below. This parameter does

not affect ABB Drives profiles. Note that while a wide range of

resolutions may be configured, actual performance will be limited

to the performance capabilities of the drive. (Nm = Newton x

Meter)
