ALARM 16, Short circuit
There is short-circuiting in the motor or on the motor
terminals.
Turn off the frequency converter and remove the
short-circuit.
WARNING/ALARM 17, Control word timeout
There is no communication to the frequency convert-
er.
The warning will only be active when par.8-04
Control
Word Timeout Function is NOT set to OFF.
If par.8-04
Control Word Timeout Function is set to
Stop
and
Trip
, a warning appears and the frequency
converter ramps down until it trips, while giving an
alarm.
WARNING
Live Electrical Components!
Troubleshooting:
Check connections on the serial communication
cable.
Increase par.8-03
Control Word Timeout Time
Check operation of the communication equip-
ment.
Verify proper installation based on EMC require-
ments.
WARNING 23, Internal fan fault
The fan warning function is an extra protection func-
tion that checks if the fan is running / mounted. The
fan warning can be disabled in par.14-53
Fan Moni-
tor ([0] Disabled).
For the D, E, and F Frame drives, the regulated volt-
age to the fans is monitored.
WARNING
Disconnect power before proceeding.
Troubleshooting:
Check fan resistance.
Check soft charge fuses.
WARNING 24, External fan fault
The fan warning function is an extra protection func-
tion that checks if the fan is running / mounted. The
fan warning can be disabled in par.14-53
Fan Moni-
tor ([0] Disabled).
For the D, E, and F Frame drives, the regulated volt-
age to the fans is monitored.
Troubleshooting:
Check fan resistance.
Check soft charge fuses.
WARNING/ALARM 28, Brake check failed
Brake resistor fault: the brake resistor is not connec-
ted or not working.
Check par.2-15
Brake Check.
ALARM 29, Heatsink temp
The maximum temperature of the heatsink has been
exceeded. The temperature fault will not be reset un-
til the temperature falls below a defined heatsink
temperature. The trip and reset point are different
based on the drive power size.
Troubleshooting:
Ambient temperature too high.
Too long motor cable.
Incorrect clearance above and below the drive.
Dirty heatsink.
Blocked air flow around the drive.
Damaged heatsink fan.
For the D, E, and F Frame Drives, this alarm is based
on the temperature measured by the heatsink sensor
mounted inside the IGBT modules. For the F Frame
drives, this alarm can also be caused by the thermal
sensor in the Rectifier module.
