10 ODVA SPEED
SCALE
Defines the speed scale in the ODVA AC/DC
drive profile. Units of reference and actual
speeds 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.
Speed unit = RPM X 2
(-1 X ODVA speed scale value)

1)
Use the ODVA speed scale value when reading/writing parameter ODVA
SPEED 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 speed scale value of the drive parameter when reading/writing
parameter ODVA SPEED 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.
