Miscellaneous
(EE ERROR CTRL CARD)
There is a fault in the EEPROM on the control
card. The frequency converter will continue to
function, but is likely to fail at the next power-up.

Auto-optimisation not OK
(AUTO MOT ADAPT FAIL)
A fault has been found during automatic motor
adaptation. The text shown in the display indicates a
fault message. The figure after the text is the error code,
which can be seen in the fault log in parameter 615.

WARNING 23
Fault during brake test (BRAKE TEST FAILED):
The brake test is only run after power-up. If Warning
has been selected in parameter 404, the warning
will come when the brake test finds a fault.
The brake test may fail for the following reasons:
No brake resistor connected or fault in the
connections; defective brake resistor or defective
brake transistor. A warning or alarm will mean
that the brake function is still active.
WARNING 25
Brake resistor fault
(BRAKE RESISTOR FAULT):
The brake resistor is monitored during operation and
if it short-circuits, the brake function is disconnected
and the warning comes up. The frequency converter
will still be able to work, although without the
brake function. Turn off the frequency converter
and replace the brake resistor.
ALARM/WARNING 26
Brake resistor power 100%
(BRAKE PWR WARN 100%):
The power transmitted to the brake resistor is
calculated as a percentage, as a mean value over the
last 120 sec., on the basis of the resistance value of
the brake resistor (parameter 401) and the intermediate
circuit voltage. The warning is active when the
dissipated braking power is higher than 100%. If Trip
[2] has been selected in parameter 403, the frequency
converter will cut out while giving this alarm.
WARNING 27
Brake transistor fault
(BRAKE IGBT FAULT):
The brake transistor is monitored during operation and
if it short-circuits, the brake function is disconnected
and the warning comes up. The frequency converter
will still be able to run, but since the brake transistor has
short-circuited, substantial power will be transmitted
to the brake resistor, even if it is inactive.
Turn off the frequency converter and remove
the brake resistor.
Warning: There is a risk of substantial power
being transmitted to the brake resis- tor if
the brake transistor has short-circuited.
ALARM: 29
Heat sink temperature too high
(HEAT SINK OVER TEMP.):
If the enclosure is IP 00 or IP 20, the cut-out
temperature of the heat-sink is 90°C. If IP 54 is
used, the cut-out temperature is 80°C.
