Information about the status of the device and messages is indicated in the
Status word . The Status
word
is composed of 16 bits the meanings of which are described in the table below:
Actual speed
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
MSB LSB
This is actual speed of the frequency converter. The scaling is –10000...10000. In the application, the
value is scaled in percentage of the frequency area between set minimum and maximum frequency.
Control word
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
- - - - - - - - - - - - - RST DIR RUN
In Vacon applications, the three first bits of the control word are used to control the frequency
converter. However, you can customise the content of the control word for your own applications
because the control word is sent to the frequency converter as such.
Speed reference
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
MSB LSB
This is the Reference 1 to the frequency converter. 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.
