Troubleshooting
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, 5 V, +/-18 V. When powered with three-
phase AC line 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 big motor
The motor is too big for the AMA to be carried out.
ALARM 54, AMA small motor
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.
5-12

(except when starting or
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 resistances
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 adjustable
frequency drive (via serial communication, digital I/
O, or by pressing the reset button on the keypad).
WARNING 61, Tracking error
An error has been detected between the calculated
motor speed and the speed measurement from the
feedback device. The function for warning/alarm/dis-
Motor Feedback Loss Function
able is set in 4-30,
Motor Feedback Speed Error
setting in 4-31,
allowed error time in 4-32,
out
. During a commissioning procedure the function
may be effective.
WARNING 62, Output frequency at maximum
limit
The output frequency is higher than the value set in
par.4-19 Max Output Frequency
WARNING 64, Voltage limit
The load and speed combination demands a motor
voltage higher than the actual DC link voltage.
WARNING/ALARM/TRIP 65, Control card
overtemperature
Control card overtemperature: The cutout tempera-
ture of the control card is 176°F [80 C].
WARNING 66, Heatsink temperature low
This warning is based on the temperature sensor in
the IGBT module.
ALARM 67, Option module configuration has
changed
One or more options have either been added or re-
moved since the last power-down.
