F30027: Precharging DC link
time monitoring
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
• The power unit DC link was not able to
be pre-charged within the expected
time.
There is no line supply voltage con-
nected.
• The line contactor/line side switch has
not been closed.
• The line supply voltage is too low.
• The pre-charging resistors are over-
heated as there were too many pre-
charging operations per time unit
• The pre-charging resistors are over-
heated as the DC link capacitance is
too high.
• The pre-charging resistors are over-
heated.
• The pre-charging resistors are over-
heated as the line contactor was
closed during the DC link fast dis-
charge through the Braking Module.
• The DC link has either a ground fault
or a short-circuit.
• The pre-charging circuit is possibly
Check the line supply voltage at the input ter-
minals.
F30036: Internal over-
temperature
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The temperature inside the drive has ex-
ceeded the permissible temperature limit.
• Insufficient cooling, fan failure.
• Overload.
• Surrounding air temperature too high.
• Check whether the fan is running.
• Check the fan elements.
• Check whether the surrounding air temper-
ature is in the permissible range.
Notice:
This fault can only be acknowledged once the
permissible temperature limit minus 5 K has
F30050: 24 V supply over-
voltage
Reaction: OFF2
Acknowledgement: POWER
The voltage monitor signals an overvolt-
age fault on the module.
•
Check the 24 V power supply.
• Replace the module if necessary.
F30071: No new actual
values received from the
power unit module
Reaction: OFF2
Acknowledgement:
The number of actual value telegrams
from the power unit module that have
failed has exceeded the permissible num-
ber.
Replace the module if necessary.
