and FBActualSpeed

The FBSpeedReference value is signed in the range of -10000...10000d (d8f0...2710h). The given
reference is scaled in percentage between minimum and maximum frequency parameters by
application. The value 0 corresponds to minimum frequency and the value 10000d corresponds to
maximum frequency. The scale of the value is 0.01%. Negative value indicates direction. If direction
bit in control word is set (means direction should be counter-clockwise) and reference is negative,
motor will run to clockwise spite the direction bit.
The FBActualSpeed value is signed in the range of -10000...10000d (d8f0...2710h). Actual speed is
scaled in percentage between minimum and maximum frequency parameters by application. The
value 0 corresponds to minimum frequency and the value 10000d corresponds to maximum
frequency. The scale of the value is 0.01%.

Process data

The Process Data variables are vendor-specific variables that can be communicated to and from the
AC drive. Eight process data items can be communicated between PLC and drive. Some drives and
firmware versions can support up to 16 process data items in single telegram. If drive does not
support 9-16 PD items, then PDI 9-16 are ignored and PDO 9-16 are zeros. For details, see
Chapter 16 "Appendix 6 - Fieldbus option board communication" and Chapter 17 "APPENDIX 7 -
parameters for application developers".
Values sent from the drive to the PLC are called ProcessDataOut variables, while the values sent
from the PLC to the drive are called ProcessDataIn variables. The contents of the ProcessDataOut
variables can be parameterized in the AC drive using a feature known as Fieldbus Process Data
mapping. See Chapter 11.8 "FIELDBUS PROCESS DATA MAPPING AND SCALING" for details.
