•
If a parameter value is requested by the master, the values in PWE1 and
PWE2 of the master telegram to the inverter are ignored.
•
The meaning of the 3
rd
and 4
th
words, PWE1 and PWE2 is dependent on
whether variable or fixed length PKW has been selected using P2013.
The examples should explain this more clearly later in this section.
•
The MICROMASTER 420 parameter list must be consulted to understand
the meaning of the parameter values, and their appropriate settings.
