Actual speed (output process data)
This is actual speed of the AC drive. 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 AC drive. By using control word it is
possible to control the operation of the drive. The meanings of the bits of control word are explained
