ALARM 39, Heatsink sensor
No feedback from the heatsink temperature sensor.
The signal from the IGBT thermal sensor is not avail-
able on the power card. The problem could be on the
power card, on the gate drive card, or the ribbon ca-
ble between the power card and gate drive card.
WARNING 40, Overload of Digital Output Ter-
minal 27
Check the load connected to terminal 27 or remove
short-circuit connection. Check par.5-01
Mode.
WARNING
Disconnect power before proceeding.
WARNING 41, Overload of Digital Output Ter-
minal 29
Check the load connected to terminal 29 or remove
short-circuit connection. Check par.5-02
Mode.
WARNING
Disconnect power before proceeding.
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 re-
move short-circuit connection. Check par.5-32
X30/6 Digi Out (MCB 101).
For X30/7, check the load connected to X30/7 or re-
move short-circuit connection. Check par.5-33
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, 5V, +/- 18V. When powered with three
phase mains voltage, all three supplied are moni-
tored.
WARNING 47, 24 V supply low
The 24 Vdc is measured on the control card.
WARNING 48, 1.8 V supply low
The 1.8 Vdc supply used on the control card is outside
of allowable limits. The power supply is measured on
the control card.
WARNING 49, Speed limit
When the speed is not within the specified range in
par. 4-11 and par. 4-13. the drive will show a warning.
When the speed is below the specified limit in par.
1-86 Trip Speed Low [RPM]
stopping) the drive will trip.

ALARM 50, AMA calibration failed
Contact your Trane supplier.
ALARM 51, AMA check Unom and Inom
The setting of motor voltage, motor current, and mo-
tor power is presumably wrong. Check the settings.
ALARM 52, AMA low Inom
The motor current is too low. Check the settings.
ALARM 53, AMA motor too big
The motor is too big for the AMA to be carried out.
ALARM 54, AMA motor too small
The motor is too big for the AMA to be carried out.
ALARM 55, AMA Parameter out of range
The parameter values found from the motor are out-
side acceptable range.
ALARM 56, AMA interrupted by user
The AMA has been interrupted by the user.
ALARM 57, AMA timeout
Try to start the AMA again a number of times, until
the AMA is carried out. Please note that repeated runs
may heat the motor to a level where the resistance Rs
and Rr are increased. In most cases, however, this is
not critical.
ALARM 58, AMA internal fault
Contact your Trane supplier.
WARNING 59, Current limit
The current is higher than the value in par.4-18
rent Limit.
WARNING 60, External interlock
External interlock has been activated. To resume nor-
mal operation, apply 24 Vdc to the terminal program-
med for external interlock and reset the frequency
converter (via serial communication, digital I/O, or by
pressing reset button on keypad).
WARNING 61, Tracking error
An error has been detected between calculated motor
speed and speed measurement from feedback de-
vice. The function for Warning/Alarm/Disable is set in
