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 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
See also functional firmware description: "Ready".
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. Signal
