Help in the event of errors
162 BA8230
Heatsink overtemperature
Cause: The NTC for monitoring heatsink temperature registered that the temperature
was too high. A warning is generated 5 °C before the error is triggered and this is also
entered in the event log.
Remedy:
Check operation of the fan. Check the wiring of the fan and the NTC.
Wire break 4-20mA
Cause: One of the analog demand inputs, main demand :27/:28 or additional demand
:29/:30, is set as the line current interface 4...20 mA and a current of less than 2 mA is
flowing.
Remedy:
Check the wiring. The monitor can be disabled with the parameter "4-20mA monitor”.
Then the event is only recorded in the event log.
AUTO RESTART (AWE)
When the mains supply returns, the AWE auto restart facility becomes active. The
inverter can also be switched on automatically by the auto restart facility without a
change in the level of the ON signal. The function is activated with the AWE time
parameter.
DC link undervoltage
The voltage on the link fell below a minimum value so that operation was no longer
possible. Shut-down without an error trigger occurred, i.e. no entry in the error log and
no need for acknowledgement.
Failure, Track A
Track A on the incremental encoder failed. A warning was generated. An error shut-
down only occurs when both tracks fail, as the encoder interface is able to
compensate for failure of one track as long as the direction does not change.
Failure, Track B
Track B on the incremental encoder failed. A warning was generated. An error shut-
down only occurs when both tracks fail since the encoder interface is able to
compensate for failure of one track as long as the direction does not change.
