8. General Specifications and Troubleshooting
WARNING 60, External Interlock:
External Interlock has been activated. To resume normal operation, apply
24 VDC to the terminal programmed for External Interlock and reset the
frequency converter (via Bus, Digital I/O or by pressing [Reset]).
WARNING 62, Output Frequency at Maximum Limit:
The output frequency is limited by the value set in par. 4-19 Max
Frequency
WARNING 64, Voltage Limit:
The load and speed combination demands a motor voltage higher than
the actual DC link voltage.
WARNING/ALARM/TRIP 65, Control Card Over Temperature:
Control card over temperature: The cut-out temperature of the control
card is 80° C.
WARNING 66, Heatsink Temperature Low:
The heat sink temperature is measured as 0° C. This could indicate that
the temperature sensor is defective and thus the fan speed is increased
to the maximum in case the power part or control card is very hot.
If the temperature is below 15° C the warning will be present.
ALARM 67, Option Configuration has Changed:
One or more options has either been added or removed since the last
power-down.
ALARM 68, Safe Stop:
8
Safe Stop has been activated. To resume normal operation, apply 24 VDC
to terminal 37 then send a Reset signal (via Bus, Digital I/O or by pressing
[Reset]).
ALARM 70, Illegal Frequency Converter Configuration:
Actual combination of control board and power board is illegal.
ALARM 80, Drive Initialised to Default Value:
Parameter settings are initialised to default setting after a manual (three-
finger) reset or via par. 14-22 Operation
WARNING/ALARM 92, NoFlow:
A no load situation has been detected for the system. See parameter
group 22-2*.
WARNING/ALARM 93, Dry Pump:
A no flow situation and high speed indicates that the pump has run dry.
See parameter group 22-2*
WARNING/ALARM 94, End of Curve:
Feed back stays lower than the set point, which may be indicates a leak-
age in the pipe system. See parameter group 22-5*
WARNING/ALARM 95, Broken Belt:
Torque is below the torque level set for no load indicating a broken belt.
See parameter group 22-6*
WARNING 96, Start Delayed:
Start of the motor has been delayed due to short cycle protection is ac-
tive. See parameter group 22-7*.
WARNING 97, Stop Delayed:
Stop of the motor has been delayed due to short cycle protection is active.
See parameter group 22-7*
WARNING 98, Clock Fault:
Date and time has not been set or any back up mounted has failed. See
parameter group 0-7*.
WARNING 200, Fire Mode:
The input command Fire Mode is active. See parameter group 24-0*

MG.11.B7.02 - VLT
WARNING 201, Fire M was Active.:
The input command Fire Mode has been active, but now deactivated. See
parameter group 0-7*
WARNING 202, Fire M Limits Exceeded:
One or more warranty voiding alarms have been suppressed during Fire
Mode. See parameter group 0-7*
ALARM 250, New Spare Part:
The power or Switch Mode Power Supply has been exchanged. The fre-
quency converter type code must be restored in the EEPROM. Select the
correct type code in Par 14-23 according to the label on unit. Remember
to select 'Save to EEPROM' to complete.
ALARM 251, New Type Code:
The frequency converter has got a new type code.
