P2.9.7.1 Freq. Supply Response ID1627
0 = No response
1 = Warning
2 = Fault
P2.9.7.2 Freq. D7 Response
0 = No response
1 = Warning
2 = Fault
P2.9.7.3 Freq. Low Warning Limit
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
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
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
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
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.
