WARNING/ALARM 34, Fieldbus communication fault
The fieldbus on the communication option card is not
working.
WARNING/ALARM 35, Out of frequency range:
This warning is active if the output frequency has reached the
high limit (set in par. 4-53) or low limit (set in par. 4-52). In
Process Control, Closed Loop (par. 1-00) this warning is
displayed.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to the
frequency converter is lost and par. 14-10 Mains Failure is NOT
set to OFF. Check the fuses to the frequency converter

ALARM 39, Heatsink sensor
No feedback from the heatsink temperature sensor.
The signal from the IGBT thermal sensor is not available on the
power card. The problem could be on the power card, on the
gate drive card, or the ribbon cable between the power card
and gate drive card.
WARNING 40, Overload of Digital Output Terminal 27
Check the load connected to terminal 27 or remove short-
circuit connection. Check par. 5-00 Digital I/O Mode and
par. 5-01 Terminal 27 Mode.
WARNING 41, Overload of Digital Output Terminal 29
Check the load connected to terminal 29 or remove short-
circuit connection. Check par. 5-00 Digital I/O Mode and
par. 5-02 Terminal 29 Mode.
WARNING 42, Overload of Digital Output on X30/6 or Overload
of Digital Output on X30/7
For X30/6, check the load connected to X30/6 or remove
short-circuit connection. Check par. 5-32 Term X30/6 Digi Out
(MCB 101).
For X30/7, check the load connected to X30/7 or remove
short-circuit connection. Check par. 5-33 Term X30/7 Digi Out
(MCB 101).
