8.4.8 Parameter Number (PNU)
Bits 0–11 transfer parameter numbers. The function of the relevant parameter is defined in the parameter description in the VLT®
Flow Drive FC 111 Programming Guide.
8.4.9 Index (IND)
The index is used with the parameter number to read/ write access parameters with an index, for example, parameter 15-30 Alarm
Log: Error Code. The index consists of 2 bytes: a low byte and a high byte. Only the low byte is used as an index.
8.4.10 Parameter Value (PWE)
The parameter value block consists of 2 words (4 bytes), and the value depends on the defined command (AK). The master prompts
for a parameter value when the PWE block contains no value. To change a parameter value (write), write the new value in the PWE
block and send from the master to the follower.
