Troubleshooting
ALARM 81, CSIV corrupt
CSIV file has syntax errors.
ALARM 82, CSIV parameter error
CSIV failed to initialise a parameter.
ALARM 83, Illegal option combination
The mounted options are incompatible.
ALARM 84, No safety option
The safety option was removed without applying a general
reset. Reconnect the safety option.
ALARM 88, Option detection
A change in the option layout was detected.
Parameter 14-89 Option Detection is set to [0] Frozen config-
uration and the option layout has been changed.
•
To apply the change, enable option layout
changes in parameter 14-89 Option Detection.
•
Alternatively, restore the correct option configu-
ration.
WARNING 89, Mechanical brake sliding
The hoist brake monitor has detected a motor speed > 10
RPM.
ALARM 90, Feedback monitor
Check the connection to encoder/resolver option and
eventually replace the MCB 102 or MCB 103.
ALARM 91, Analog input 54 wrong settings
Switch S202 has to be set in position OFF (voltage input)
when a KTY sensor is connected to analog input terminal
54.
ALARM 99, Locked rotor
Rotor is blocked.
WARNING/ALARM 104, Mixing fan fault
The fan is not operating. The fan monitor checks that the
fan is spinning at power-up or whenever the mixing fan is
turned on. The mixing-fan fault can be configured as a
warning or an alarm trip in parameter 14-53 Fan Monitor.
Troubleshooting
•
Cycle power to the frequency converter to
determine if the warning/alarm returns.
WARNING/ALARM 122, Mot. rotat. unexp.
The frequency converter performs a function that requires
the motor to be at standstill, e.g. DC hold for PM motors.
WARNING 123, Motor Mod. Changed
The motor selected in parameter 1-11 Motor Model is not
correct and the selection has been corrected.
WARNING 163, ATEX ETR cur.lim.warning
The frequency converter has run above the characteristic
curve for more than 50 s. The warning is activated at 83%
and deactivated at 65% of the permitted thermal overload.
ALARM 164, ATEX ETR cur.lim.alarm
Operating above the characteristic curve for more than
60 s within a period of 600 s activates the alarm, and the
frequency converter trips.

Programming Guide
WARNING 165, ATEX ETR freq.lim.warning
The frequency converter is running more than 50 s below
the permitted minimum frequency (parameter 1-98 ATEX
ETR interpol. points freq.).
ALARM 166, ATEX ETR freq.lim.alarm
The frequency converter has operated more than 60 s (in a
period of 600 s) below the permitted minimum frequency
(parameter 1-98 ATEX ETR interpol. points freq.).
WARNING 220, Configuration file version not supported
The frequency converter does not support the current
configuration file version. Customisation is aborted.
ALARM 246, Power card supply
This alarm is only for enclosure size F frequency converters.
It is equivalent to Alarm 46. The report value in the alarm
log indicates which power module generated the alarm:
WARNING 250, New spare part
A component in the frequency converter has been
replaced.
Troubleshooting
•
WARNING 251, New typecode
The power card or other components have been replaced
and the type code has been changed.
Troubleshooting
•
ALARM 430, PWM Disabled
The PWM on the power card is disabled.
