DURADRIVE Drive Controllers DURADRIVE HDC01.1 Drive Controller 4-35
DOK-DURADR-HDC01.1****-PR02-EN-P
Depending on operating mode and parameter programming a number of
monitoring functions are conducted. If a condition is detected that still
allows for correct operations but would eventually lead to an error, then
the warning is set to high.
⇒ See also firmware functional description.
If the unit is ready for the drive enable, then the output ready is set to
high.
The output is set to low
• with a pending error
• with DC bus voltage < (0.75 x threshold value of applied mains
voltage)
• with lacking control voltage
Once the minimum voltage in the power DC bus is reached, then the
controller is ready to output power and the U
D
output is set to high.
Delay time t

from applying mains voltage to the setting of the UD signal is
