Grid Frequency - Danfoss Vacon NXP Applications Manual

Description of parameters
P2.9.6.2 Voltage Low Warning Limit
Low limit for a warning indication. A percentage value from a set supply voltage
parameter.
P2.9.6.3 Voltage Low Trip Limit
Low limit for a fault indication. A percentage value from a set supply voltage parameter.
The common tripping limit of the land based grid code standard is 80 % of Un within 200
ms.
P2.9.6.4 Voltage High Warning Limit
High limit for a warning indication. A percentage value from a set supply voltage
parameter.
P2.9.6.5 Voltage High Trip Limit
High limit for a fault indication. A percentage value from a set supply voltage parameter.
The common tripping limit of the land based grid code standard is 115 % of Un within 200
ms.
P2.9.6.6 Voltage Trip Delay
Delay to a fault when the voltage has exceeded the fault levels.

Grid frequency

A monitoring function for the drive output frequency and the measured frequency from OPT-D7.
Will also trip this when operating in pure AFE mode.
NOTE: This functionality is not Grid Code functionality even if functionality may be similar.
