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
5-00 Digital I/O Mode
and
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
5-00 Digital I/O Mode
and
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
the short-circuit connection. Check
5-32 Term X30/6 Digi
Out (MCB 101)
.
For X30/7, check the load connected to X30/7 or remove
the short-circuit connection. Check
5-33 Term X30/7 Digi
Out (MCB 101)
.
ALARM 46, Power card supply
The supply on the power card is out of range.
There are three power supplies generated by the switch
mode power supply (SMPS) on the power card: 24 V, 5 V,
±
18 V. When powered with 24 V DC with the MCB 107
option, only the 24 V and 5 V supplies are monitored.
When powered with three phase AC line voltage, all three
supplies are monitored.
WARNING 47, 24 V supply low
The 24 V DC is measured on the control card. The external
24 V DC backup power supply may be overloaded,
otherwise contact the Danfoss supplier.
WARNING 48, 1.8 V supply low
The 1.8 V DC supply used on the control card is outside of
allowable limits. The power supply is measured on the
control card. Check for a defective control card. If an
option card is present, check for an overvoltage condition.
WARNING 49, Speed limit
When the speed is not within the specified range in
4-11 Motor Speed Low Limit [RPM]
and
4-13 Motor Speed
High Limit [RPM]
, the adjustable frequency drive shows a
warning. When the speed is below the specified limit in
1-86 Trip Speed Low [RPM]
(except when starting or
stopping), the adjustable frequency drive will trip.
