Gradient of P Limit
AU
Power speed limit (WGra) is the lamp speed of active power output, and is defined as a percentage of the rated
power per minute. Nominal lamp time (Tn) is the nominal time for 100 % change of the power output.

Limit Control
AU
CAUTION
If at least one limit control function is enabled when an energy meter is not connected,
an error occurs and an inverter is not operated.
■
Export Hard Limit
: If the inverter output active power exceeds the Export Hard Limit for 15 seconds, the
inverter is blocked from the Export Hard Limit Time system.
■
Export Soft Limit
: If the inverter output active power exceeds the Export Soft Limit, the inverter decreases the
output apparent power below the Export Soft Limit Level.
■
Generation Hard Limit
: If the inverter output active power exceeds the Generation Hard Limit for 15 seconds,
the inverter is blocked from the Generation Hard Limit Time system.
■
Generation Soft Limit
: If the inverter output apparent power exceeds the Generation Soft Limit, the inverter
decreases the output apparent power below the Generation Soft Limit Level within the Generation Soft Limit
Level.
