Faults F0035
Function chart number: -
After a power failure (F0003 "Undervoltage"), the "Automatic restart" function
(enabled using P1210) automatically powers-up the drive inverter again. Any faults
are automatically acknowledged by the drive inverter.
When it comes to power failures (line supply failure), then a differentiation is made
between the following conditions:
Line undervoltage (brownout)
"Line undervoltage" is a situation where the line supply is interrupted and returns
before (if installed) the BOP display has gone dark (this is an extremely short line
supply interruption where the DC link hasn't completely collapsed).
Line failure (blackout)
"Line failure" is a situation where the display has gone dark (this represents a
longer line supply interruption where the DC link has completely collapsed) before
the line supply returns.
The automatic restart function P1210 is shown in the following diagram (refer to
Table 3-22) as a function of external states / events.
