1514131211109876543210Bit no.
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 Output frequency high
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.
