Operating Guide
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 in the power card,
in the gatedrive card, or the ribbon cable between the
power card and the 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. 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 X30/6, check the load connected to X30/6 or remove
the short circuit connection. Check parameter 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 parameter 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 3 supplies powered 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 VLT
107 option, only the 24 V and 5 V supplies are monitored.
When powered with 3-phase mains voltage, all 3 supplies
are monitored.
WARNING 47, 24 V supply low
The 24 V DC supply is measured on the control card. The
external 24 V DC back-up 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
the allowable limits. The 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
parameter 4-11 Motor Speed Low Limit [RPM] and
parameter 4-13 Motor Speed High Limit [RPM], the frequency
converter shows a warning. When the speed is below the
specified limit in parameter 1-86 Trip Speed Low [RPM]
(except when starting or stopping) the frequency converter
trips.
ALARM 50, AMA calibration failed
Contact the Danfoss supplier or Danfoss Service.
ALARM 51, AMA check U
The settings for motor voltage, motor current, and motor
power are wrong. Check the settings in parameters 1-20 to
1-25.
