Maximum limit is defined by parameter
Minimum limit is defined by parameter
If the network employs the ODVA AC/DC drive profile and the drive is operating in the
scalar mode, the fieldbus speed reference unit is always rpm. The fieldbus adapter
module can provide the drive with a frequency reference, if parameter FB PAR 23
ODVA SPEED SCALE or FB PAR 10 ODVA SPEED SCALE is set, but this might not
guarantee the accurate speed reference. If there is no accurate speed reference and
the EXT1 reference is used, set parameter
(36) to convert the ODVA AC/DC speed reference and actual value type to Hz. In
addition, you can set the decimal point location for ODVA frequency reference values
by selecting the correct scaling format with parameter
Note: The ODVA AC/DC reference conversion is available only for EXT1 in the scalar
mode. The supported networks are Ethernet/IP and DeviceNet.
