Table 7.4 Internal Fault Codes
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 45, Ground fault 2
Ground fault.
Troubleshooting
•
Check for proper grounding and loose
connections.
•
Check for proper wire size.
•
Check motor cables for short-circuits or leakage
currents.
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.
Troubleshooting
•
Check for a defective power card.
•
Check for a defective control card.
•
Check for a defective option card.
•
If a 24 V DC power supply is used, verify proper
supply power.
WARNING 47, 24 V supply low
The 24 V DC is measured on the control card. This alarm
arises when the detected voltage of terminal 12 is lower
than 18 V.
Troubleshooting
•
Check for a defective control card.
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 trips.
ALARM 50, AMA calibration failed
Contact Danfoss supplier or Danfoss service department.
ALARM 51, AMA check U
nom
and I
nom
The settings for motor voltage, motor current and motor
power are wrong. Check the settings in parameters 1-20 to
1-25.
ALARM 52, AMA low I
nom
The motor current is too low. Check the settings.
