P2.9.7.1
Freq. Supply Response ID1627
0 = No response
1 = Warning
2 = Fault
P2.9.7.2
Freq. D7 Response
ID1628
0 = No response
1 = Warning
2 = Fault
P2.9.7.3
Freq. Low Warning Limit
ID1780
Low limit for a warning indication. A percentage value from a set supply frequency
parameter. This also limits the adjusted frequency references.
P2.9.7.4
Freq. Low Trip Limit
ID1781
Low limit for a fault indication. A percentage value from a set supply frequency
parameter. Use G2.6.3 Frequency limits for final and immediate protection.
The common tripping limit of the land based grid code standard is 47.5 Hz within 200 ms.
P2.9.7.5
Freq. High Warning Limit
ID1783
High limit for a warning indication. A percentage value from a set supply frequency
parameter. This also limits the adjusted frequency references.
P2.9.7.6
Freq. High Trip Limit
ID1784
High limit for a fault indication. A percentage value from a set supply frequency
parameter. Use G2.6.3 Frequency limits for final and immediate protection.
The common tripping limit of the land based grid code standard is 50.2-51.5 Hz within
200 ms.
P2.9.7.7
Freq.
Trip
Delay
ID1785
Delay to a fault when the frequency has exceeded the fault levels.
5.9.8
Supply voltage
There is a tripping function for the drive output voltage. It is possible that the drive output voltage is
higher (or lower) than the grid voltage, depending on the voltage compensation for LCL and
transformer.
P2.9.8.1
Voltage, Supply response
ID1629
0 = No response
1 = Warning
2 = Fault
