■ Present output frequency
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).
E
xample - Status word and present output frequency:
and present output frequency: The master receives
a status message from the frequency converter
saying that the present output frequency is 50
% of the output frequency range.
Par. 201 Output
frequency low limit =
0Hz
Par. 202 Output
frequency high limit =
50 Hz
Status word = 0F03 Hex. Status

Output frequency = 2000 Hex. 50 % of
the frequency range,
correspondingto25Hz.
