This disables UU trip state and enables charge up relay for low voltage use. It is necessary to use a digital input to set this bit. This input is
used to provide interlock before return to full volts from low voltage supply. The drive healthy bit is dropped after a delay of 20ms to allow
charging up relay to drop. This interlock mechanism protects the drive from applying full power to DC bus caps without a charging resistor.
When this parameter is activated by user trip 32 Ph is disabled.
0 = Phase failure protection enabled
1 = Phase failure protection disabled
When this parameter is activated by user trip 19 It.Br is disabled.
0 = Internal braking resistor protection enabled
1 = Internal braking resistor protection disabled
The M'Ax power stage is rated at 200% for 2 seconds. The drive includes a thermal protection system. The drive over temperature alarm bit
is set if this parameter is greater than 75%. The drive will trip on O.ht1 if 10.56 >100%.
Refer to parameter 10.53.
