NOTE!
Reference Backup
The last frequency Reference set by the keys
inverter is stopped or the AC power is removed, provided P120 = 1 (Reference
Backup active is the factory default). To change the frequency reference before
starting the inverter, the value of parameter P121 must be changed.
Parameters P002 to P099 are reserved for the display of "read-only" values. The
factory default display when power is applied to the inverter is P002. Motor speed
in rpm. The user can scroll through the various read-only parameters or use the
factory configured display of the key values. This is done by pressing the start
key .
