4.5.3. Bus Reference Value under Instances 100/150 and 101/151

The frequency reference value is transmitted

to the frequency converter in the form of a 16-

bit word. The value is transmitted as a whole

number (-32767 to 32767). Negative figures

are formatted by means of 2’s complement.

The bus reference has the following format:

100% = 4000 Hex

4.5.4. Actual Output Frequency under Instances 100/150 and

101/151

The value of the actual output frequency of

the frequency converter is transmitted in the

form of a 16-bit word. The value is transmitted

as a whole number (-32767 -> 32767) Nega-

tive figures are formed by means of 2’s com-

plement.

Slave master→ 16 bit

STW Actual ref. RPM

The actual output frequency has the following format:

-32767 ->+32767.

-16384 (C000 Hex) corresponds to -100%, and 16384 (4000 Hex) corresponds to 100%.
