The value of the present output frequency of the
frequency converter at any given time is transmitted
as a 16-bit word. The value is transmitted in the form
of whole numbers 0 - ±32767 (±200 %).
16384 (4000 Hex) corresponds to 100 %.
The output frequency has the following format:
0-16384 (4000 Hex)
≅
0-100 % (Par. 201
Output
frequency low limit
- Par. 202

limit
).
Example - Status word
and present output frequency:
The master receives a status message from the VLT
frequency converter saying that the present output
frequency is 50 % of the output frequency range.
Par. 201
Output frequency low limit
=
0 Hz
Par. 202
Output frequency high limit
=
50 Hz
Status word =
0F03 Hex. Status message
Output frequency =
2000 Hex. 50 % of the
frequency range,
corresponding to 25 Hz.
