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.
