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
short-circuit connection. Check par. E-56 X30/6 Digital Out
(OPCGPIO).
For X30/7, check the load connected to X30/7 or remove
short-circuit connection. Check par. E-57 Term X30/7
Digital Out (OPCGPIO).
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 VDC 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
supplied are monitored.
WARNING 47, 24 V supply low
The 24 VDC is measured on the control card. The external
24 VDC backup power supply may be overloaded,
otherwise contact your Danfoss supplier.
WARNING 48, 1.8 V supply low
The 1.8 Volt DC supply used on the control card is outside
of allowable limits. The power supply is measured on the
control card.
WARNING 49, Speed limit
The speed is not within the specified range in
4-11 Motor
Speed Low Limit [RPM]
and
4-13 Motor Speed High Limit
[RPM]
.
ALARM 50, Auto Tune calibration failed
Contact your Danfoss supplier.
ALARM 51, Auto Tune check Unom and Inom
The setting of the motor voltage, motor current, and
motor power is presumably wrong. Check the settings.
