FbEq Description
Parameters related to internal grid monitoring.
Note: Group 44 is write-protected. It can be write-enabled by giving
a password with parameter
Defines the usage mode of the internal grid monitoring. Grid
monitoring is based on the voltage measurement via the NAMU
board.
0 Internal grid monitoring is disabled.
1 Internal grid monitoring is enabled. If grid voltage and/or frequency
are outside limits that are defined by parameters 44.02...44.17, a
corresponding alarm is created and the inverter continues to
operate.
2 Internal grid monitoring is enabled. If grid voltage and/or frequency
are outside limits that are defined by parameters 44.02...44.17, a
corresponding fault is created and the inverter stops.
Defines a trip limit for under frequency fault 1. If the grid frequency

the time delay in parameter
inverter will generate an alarm or a fault according to parameter
44.01 NAMU GRIDMON
Trip limit 1
Defines a trip limit for under frequency fault 2. If the grid frequency

NAMU GRIDMON
Trip limit 2
100 = 1 s Defines a trip time for under frequency fault 1.
Trip time 1
100 = 1 s Defines a trip time for under frequency fault 2.
Trip time 2
100 = 1 Defines a trip limit for over frequency fault 1. If the grid frequency
