Actual speed (output process data)
This is actual speed of the frequency converter.
The scaling is -10000...10000. The value is scaled
in percentage of the frequency area between set
minimum and maximum frequency.
Control word (input process data)
The three first bits of the control word are used to
control the frequency converter. By using control
word it is possible to control the operation of the
drive. The meanings of the bits of control word are
explained in the table below:

Speed reference (input process data)
This is the Reference 1 to the frequency converter.
Used normally as Speed reference. The allowed
scaling is 0...10000. The value is scaled in
percentage of the frequency area between the set
minimum and maximum frequencies.
