Description of parameters
P2.9.8.2 Voltage Low Trip Limit
When the supply voltage drops below this limit, the drive will trip to an F70 Supply
voltage fault. If the drive is already at the current limit, this low voltage trip limit is not
active.
NOTE! OPT-D7 is not used for detection.
Use this function for the final protection function for the grid or the generator. Delay to
trip is 150 ms.The protection group has functions that use OPT-D7 for voltage level
protection.
P2.9.8.3 Voltage Low Warning Limit
When the supply voltage drops below this limit, the drive will give a warning. If the drive
is already at the current limit, this low voltage trip limit is not active.
NOTE! OPT-D7 is not used for detection.
P2.9.8.4 Voltage Low Warning Limit
When the supply voltage increases above this limit, the drive will give a warning.
NOTE! OPT-D7 is not used for detection.
P2.9.8.5 Voltage High Trip Limit
When the supply voltage increases above this limit, the drive will trip to an F70 Supply
voltage fault.
NOTE! OPT-D7 is not used for detection.
Use this function for the final protection function for the grid or the generator. Delay to
trip is 150 ms.The protection group has functions that use OPT-D7 for voltage level
protection.
