6.18.2 Energy saving monitor (Pr. 891 to Pr. 899)
From the power consumption estimated value during commercial power supply operation, the
energy saving effect by use of the inverter can be monitored/output.
The above parameters allow its setting to be changed during operation in any operation mode
even if "0" (initial value) is set in Pr. 77 "Parameter write selection".
