Table 5-20: Control Word
In SLX9000 applications, the three first bits of the control word are used to control the drive.
However, you can customize the content of the control word for your own applications
because the control word is sent to the drive as such.
Table 5-21: Speed Reference
This is the Reference 1 to the drive. Used normally as Speed reference. The allowed scaling is
-10000 – 10000. In the application, the value is scaled in percentage of the frequency area
between the set minimum and maximum frequencies.
