Warnings and Alarms
CAUTION
Warning: There is a risk of substantial power being
transmitted to the brake resistor if the brake transistor is
short-circuited.
WARNING/ALARM 27, Brake chopper fault
The brake transistor is monitored during operation and if it
short-circuits, the brake function disconnects and issues a
warning. The drive is still able to run, but since the brake
transistor has short-circuited, substantial power is
transmitted to the brake resistor, even if it is inactive.
Turn off the drive and remove the brake resistor.
This alarm/ warning could also occur should the brake
resistor overheat. Terminal 104 to 106 are available as
brake resistor. Klixon inputs, see section Brake Resistor
Temperature Switch.
WARNING/ALARM 28, Brake check failed
Brake resistor fault: the brake resistor is not connected or
not working.
Check B-15 Brake Check.
ALARM 29, Heatsink temp
The maximum temperature of the heatsink has been
exceeded. The temperature fault will not be reset until 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 unit sizes 4X, 5X and 6X, this alarm is based on the
temperature measured by the heatsink sensor mounted
inside the IGBT modules. For the unit sizes 6X, this alarm
can also be caused by the thermal sensor in the Rectifier
module.
Troubleshooting:
Check fan resistance.
Check soft charge fuses.
IGBT thermal sensor.
ALARM 30, Motor phase U missing
Motor phase U between the drive and the motor is
missing.
Turn off the drive and check motor phase U.
ALARM 31, Motor phase V missing
Motor phase V between the drive and the motor is
missing.
Turn off the drive and check motor phase V.

ALARM 32, Motor phase W missing
Motor phase W between the drive and the motor is
missing.
Turn off the drive and check motor phase W.
ALARM 33, Inrush fault
Too many power-ups have occurred within a short time
period. Let unit cool to operating temperature.
WARNING/ALARM 34, Network communication fault
The network on the communication option card is not
working.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to
the drive is lost and SP-10 Line failure is NOT set to OFF.
Check the fuses to the drive
ALARM 38, Internal fault
