ALARM 39, Heat sink sensor
No feedback from the heat sink 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 gatedrive card, or the ribbon cable between the
power card and gatedrive card.
WARNING 40, Overload of digital output terminal 27
Check the load connected to terminal 27 or remove the
short-circuit connection. Check parameter 5-00 Digital I/O
Mode and parameter 5-01 Terminal 27 Mode.
WARNING 41, Overload of digital output terminal 29
Check the load connected to terminal 29 or remove the
short-circuit connection. Also check parameter 5-00 Digital
I/O Mode and parameter 5-02 Terminal 29 Mode.
WARNING 42, Overload of digital output on X30/6 or
overload of digital output on X30/7
For terminal X30/6, check the load connected to terminal
X30/6 or remove the short-circuit connection. Also check
parameter 5-32 Term X30/6 Digi Out (MCB 101) (VLT
General Purpose I/O MCB 101).
For terminal X30/7, check the load connected to terminal
X30/7 or remove the short-circuit connection. Check
parameter 5-33 Term X30/7 Digi Out (MCB 101) (VLT
General Purpose I/O MCB 101).
ALARM 43, Ext. supply
®
VLT Extended Relay Option MCB 113 is mounted without
external 24 V DC. Either connect a 24 V DC external supply
or specify that no external supply is used via
parameter 14-80 Option Supplied by External 24VDC, [0] No.
A change in parameter 14-80 Option Supplied by External
24VDC requires a power cycle.

ALARM 46, Power card supply
The supply on the power card is out of range. Another
reason can be a defective heat sink fan.
There are 3 supplies generated by the switch mode supply
(SMPS) on the power card:

•
When powered with VLT
the 24 V and 5 V supplies are monitored. When powered
with 3-phase mains voltage, all 3 supplies are monitored.
