Description
Occurs when the dc-bus voltage drops below the
permissible value.
Occurs when the dc-bus voltage rises above the
permissible value.
Occurs when the output current exceeds the
permissible value.
Occurs when the maximal permissible heat sink
temperature is exceeded. (see instruction manual
part 2).
The message E.nOH appears, when the overheating
error is no longer present.
The message E.OL occurs when an overload is
present for longer than the permissible time.
The message E.OL2 occurs at frequencies < 3Hz in
dependence on the heat sink temperature.
The message E.nOL appears after the cooling
phase. (see curves in the instruction manual part 2).
Occurs 60 s after the temperature monitoring is
triggered.
Occurs when parameter CP.15 = 0 the digital input
I3 is activated.
______
Occurs when the rotation release on terminal X2.3
and/or X2.4 is not present and parameter CP.35 = 0.
Speed measurement card missing or defective.
Processor - fault
Occurs when the input voltage is too low after
startup or the ladeshunt fault didn't switch.
(Monitoring with ladeshunt relais not possible with
all unit sizes).
