Danfoss VLT HVAC Design Guide

WARNING 97, Stop delayed
Stopping the motor has been delayed due to short cycle protection is
active. See parameter group 22-7.
WARNING 98, Clock fault
Clock Fault. Time is not set or RTC clock (if mounted) has failed. See
parameter group 0-7.
WARNING 201, Fire M was Active
Fire Mode has been active.
WARNING 202, Fire M Limits Exceeded
Fire Mode has suppressed one or more warranty voiding alarms.
WARNING 203, Missing Motor
A multi-motor under-load situation was detected, this could be due to e.g.
a missing motor.
WARNING 204, Locked Rotor
A multi-motor overload situation was detected, this could be due to e.g.
a locked rotor.
ALARM 243, Brake IGBT
This alarm is only for F Frame drives. 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 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 244, Heatsink temperature
This alarm is only for F Frame drives. 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 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 245, Heatsink sensor
This alarm is only for F Frame drives. 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 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 246, Power card supply
This alarm is only for F Frame drives. 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 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 247, Power card temperature
This alarm is only for F Frame drives. 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 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 248, Illegal power section configuration
This alarm is only for F Frame drives. It is equivalent to Alarm 79. 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 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
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
Typecode Setting according to the label
on the unit. Remember to select ‘Save to EEPROM’ to complete.
ALARM 251, New type code
The frequency converter has a new type code.
