The braking IGBT continues to operate even when the drive is not enabled, and is only disabled if one of the following trips occurs or would occur if
another trip has not already become active: OI.br or It.br.
It should be noted that although the UU trip operates in a similar way to all other trips, all drive functions can still operate, but the drive cannot be
enabled. Parameter values are only loaded from EEPROM if the supply voltage is low enough for the switch mode power supply in the drive to shut
down and then it is increased to restart the drive power supplies. The only differences between UU and other trips are as follows:
1. Power down save user parameters are saved when UU trip is activated.
2. The UU trip is self-resetting when the DC bus voltage rises above the drive restart voltage level.
3. When the drive is first powered up a UU trip is initiated if the supply voltage is below the restart voltage level. This does not save power down
save parameters. If another trip occurs during power-up it is the active trip in preference to the UU trip. If this trip is cleared and the supply voltage
is still below the restart voltage threshold a UU trip is then initiated.
The following alarm warnings and display indications will flash on the right hand display when they become active.
