Danfoss VLT AHF 005 Operating Instructions

ALARM 95, Broken belt
Torque is below the torque level set for no load, indicating
a broken belt. parameter 22-60 Broken Belt Function is set
for alarm. Troubleshoot the system and reset the frequency
converter after the fault has been cleared.
ALARM 96, Start delayed
Motor start has been delayed due to short-cycle
protection. parameter 22-76 Interval between Starts is
enabled. Troubleshoot the system and reset the frequency
converter after the fault has been cleared.
WARNING 97, Stop delayed
Stopping the motor has been delayed due to short cycle
protection. parameter 22-76 Interval between Starts is
enabled. Troubleshoot the system and reset the frequency
converter after the fault has been cleared.
WARNING 98, Clock fault
Time is not set or the RTC clock has failed. Reset the clock
in parameter 0-70 Date and Time.
WARNING 201, Fire mode was active
This indicates the frequency converter had entered fire
mode. Cycle power to the unit to remove the warning. See
the fire mode data in the alarm log.
WARNING 202, Fire mode limits exceeded
While operating in fire mode one or more alarm conditions
have been ignored which would normally trip the unit.
Operating in this condition voids unit warranty. Cycle
power to the unit to remove the warning. See the fire
mode data in the alarm log.
WARNING 203, Missing motor
With a frequency converter operating multi-motors, an
under-load condition was detected. This could indicate a
missing motor. Inspect the system for proper operation.
WARNING 204, Locked rotor
With a frequency converter operating multi-motors, an
overload condition was detected. This could indicate a
locked rotor. Inspect the motor for proper operation.
ALARM 243, Brake IGBT
This alarm is only for F Frame frequency converters. It is
equivalent to Alarm 27. The report value in the alarm log
indicates which power module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 frequency
converter.
2 = right inverter module in F1 or F3 frequency
converter.
3 = right inverter module in F2 or F4 frequency
converter.
5 = rectifier module.
ALARM 244, Heatsink temperature
This alarm is only for F Frame frequency converters. It is
equivalent to Alarm 29. The report value in the alarm log
indicates which power module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 frequency
converter.
2 = right inverter module in F1 or F3 frequency
converter.
3 = right inverter module in F2 or F4 frequency
converter.
5 = rectifier module.
ALARM 245, Heatsink sensor
This alarm is only for F Frame frequency converters. It is
equivalent to Alarm 39. The report value in the alarm log
indicates which power module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 frequency
converter.
2 = right inverter module in F1 or F3 frequency
converter.
3 = right inverter module in F2 or F4 frequency
converter.
5 = rectifier module.
ALARM 246, Power card supply
This alarm is only for F Frame frequency converters. It is
equivalent to Alarm 46. The report value in the alarm log
indicates which power module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 frequency
converter.
2 = right inverter module in F1 or F3 frequency
converter.
3 = right inverter module in F2 or F4 frequency
converter.
5 = rectifier module.
ALARM 247, Power card temperature
This alarm is only for F Frame frequency converter. It is
equivalent to Alarm 69. The report value in the alarm log
indicates which power module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 frequency
converter.
2 = right inverter module in F1 or F3 frequency
converter.
3 = right inverter module in F2 or F4 frequency
converter.
5 = rectifier module.
ALARM 248, Illegal power section configuration
This alarm is only for F Frame frequency converters. It is
equivalent to Alarm 79. The report value in the alarm log
indicates which power module generated the alarm:
