Rexroth Indramat ECODRIVE03 Series User Manual

4-56 ECODRIVE03 DKC**.040, DKC**.100, DKC**.200 ECODRIVE03 Drive Controllers
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 rmware 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
 See also functional rmware description: "Ready".
Once the minimum voltage in the power DC bus is reached, then th

controller is ready to output power and the U
