 Case b: The low voltage situation takes longer than the configured 'Dip Autorestart Window' which
means the UMC switches off the relay output. But the low voltage situation is shorter than the configured
'Dip Duration' so the motor gets started automatically after an optional restart delay time (Parameter 'Dip
Autorestart Enable=On). Otherwise it stays off.
 Case c: The low voltage situation takes longer than the 'Dip Duration' time. Therefore an error is gen-
erated as soon as the dip duration exceeds the configured dip duration time.
