2.6.4.5 Current Limit Ti
The integration time for the current limit operation.
2.6.4.6 Current Limit Max Minimum
This parameter defines the minimum limit for the maximum current limit.
Use this function to limit minimum when PLC control value to zero. The value zero will
cause instability in the control. Depending on the system, the value is usually between
1% and 5%.
2.6.4.7 Current limit to Zero Mode
Defines how the maximum current limit is handled in the STOP state.
In a starting situation, the current can increase above the reference when the grid
frequency is below the base frequency. This function will decrease the starting current in
starting situations.
0 = Current limit is kept at parameter level in STOP state.
1 = Current limit is set to minimum level in STOP state.

DC voltage regulators

P2.6.5.1 Under Voltage Limit
This parameter provides the under voltage regulator limit for Island and Micro Grid
operation. A percentage value related to the nominal AC voltage of the drive.
500 Vac unit: 439
690 Vac unit: 605
P2.6.5.2 Over Voltage limit
This parameter provides the over voltage regulator limit for Island and Micro Grid
operation. A percentage value related to the nominal AC voltage of the drive.
500 Vac unit:810
690 Vac unit:1117
