Warnings and Alarms
Troubleshooting:
ALARM 67, Option module configuration has changed
One or more options have either been added or removed
since the last power-down.
ALARM 68, Safe Torque Off activated
Safe Torque Off has been activated. To resume normal
operation, apply 24 V DC to terminal 37, then send a reset
signal (via bus, digital I/O, or by pressing [Reset]). See
5-19 Terminal 37 Safe Stop.
ALARM 69, Power card temperature
The temperature sensor on the power card is either too
hot or too cold.
ALARM 70, Illegal FC Configuration
Actual combination of control board and power board is
illegal.
WARNING 73, Safe Torque Off auto restart
Safe stopped. Note that with automatic restart enabled,
the motor can start when the fault is cleared.
ALARM 79, Illegal power section configuration
The scaling card is the incorrect part number or not
9 9
installed. Also MK102 connector on the power card could
not be installed.
ALARM 80, Unit initialized to default value
Parameter settings are initialized to default settings after a
manual reset.
ALARM 244, Heatsink temperature
Report value indicates source of alarm (from left):
1-4 inverter
5-8 rectifier
ALARM 245, Heatsink sensor
No feedback from the heatsink sensor. Report value
indicates source of alarm (from left):
1-4 inverter
5-8 rectifier
ALARM 246, Power card supply
The supply on the power card is out of range. Report value
indicates source of alarm (from left):
1-4 inverter
5-8 rectifier
ALARM 247, Power card temperature
Power card overtemperature. Report value indicates source
of alarm (from left):
1-4 inverter
5-8 rectifier

Instruction Manual
ALARM 248, Illegal power section configuration
Power size configuration fault on the power card. Report
value indicates source of alarm (from left):
1-4 inverter
5-8 rectifier
ALARM 250, New spare part
The power or switch mode power supply has been
exchanged. The filter type code must be restored in the
EEPROM. Select the correct type code in 14-23 Typecode
Setting according to the label on the unit. Remember to
select 'Save to EEPROM' to complete.
ALARM 251, New type code
The filter has a new type code.
ALARM 300, Mains Cont. Fault
The feedback from the line power contactor did not match
the expected value within the allowed time frame. Contact
Danfoss or supplier.
ALARM 301, SC Cont. Fault
The feedback from the soft charge contactor did not
match the expected value within the allowed time frame.
Contact Danfoss or supplier.
ALARM 302, Cap. Overcurrent
Excessive current was detected through the AC capacitors.
Contact Danfoss or supplier.
ALARM 303, Cap. Ground Fault
A ground fault was detected through the AC capacitor
currents. Contact Danfoss or supplier.
ALARM 304, DC Overcurrent
Excessive current through the DC link capacitor bank was
detected. Contact Danfoss or supplier.
ALARM 305, Line Power Freq. Limit
The line power frequency was outside the limits. Verify
that the line power frequency is within product specifi-
cation.
ALARM 306, Compensation Limit
The needed compensation current exceeds unit capability.
Unit is running at full compensation.
ALARM 308, Resistor temp
Excessive resistor heatsink temperature detected.
ALARM 309, Mains Earth Fault
A ground fault was detected in the line power currents.
Check the line power for shorts and leakage current.
ALARM 310, RTDC Buffer Full
Contact Danfoss or supplier.
