2.6.1.5
BiPhase Fault Voltage Level.
The BiPhase fault is detected by monitoring the supply voltage. Set this value lower than
the supply voltage would be in normal operation.

Active Current limits
2.6.2.1
Output Active Current Limit
This parameter sets the active current limit for the generator side operation of the
regenerative unit. 100.0% is equal to nominal power, defined by System Rated Current.
2.6.2.2
Input Active Current Limit
This parameter sets the active current limit for the motoring side operation of the
regenerative unit. 100.0% is equal to nominal power, defined by System Rated Current.
2.6.2.3
Active Current Limit Increase Rate
ID1502
“Limit.Inc.Rate”
This parameter defines the limit increase rate. The limit will start to decrease
immediately.
P2.6.2.4
High Frequency Power Limit Function
ID1703
This parameter provides a high frequency power limit function for AFE. When the
frequency exceeds this value, power is limited with 1 Hz slope. The value 0 = Not in use.
