SFC 58 copies the specifications for the parameters to be read from DB 1 and sends them to
the inverter as a read request. No other read requests are permitted while this one is being
processed.
After the read request and a waiting time of one second, the controller takes the parameter
values from the inverter via SFC 59 and saves them in DB 2.
