Figure 5-38 Function block for reading parameters
You first have to define how many parameters (MB62), which parameter numbers (MW50,
MW52, etc.), and how many parameter indices (MW58, MB59, etc.) are read for each
parameter number. The specifications are saved in DB1.
SFC 58 copies the specifications for the parameters to be read from DB1 and sends them to
the frequency inverter as a read request. No other read requests are permitted while this one
is being processed.
