WARNING 47
24 V supply low:
The external 24 V DC backup power supply may be
overloaded, otherwise contact your Danfoss supplier.
WARNING 48
1.8 V supply low:
Contact your Danfoss supplier.
WARNING 49
Speed limit:
The speed is not within the specified range
in par. 4-11 and par. 4-12
ALARM 50
AMA calibration failed:
Contact your Danfoss supplier.
ALARM 51
AMA check Unom and Inom:
The setting of motor voltage, motor current,
and motor 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 small for the AMA to be carried out.
ALARM 55
AMA par. out of range:
The par. values found from the motor are
outside 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 Danfoss supplier.
Some typical alarm messages:
1299 - OptionSW in slot A is too old
266
Troubleshooting
MG.33.B4.02 - VLT is a registered Danfoss trademark
1300 - OptionSW in slot B is too old
1301 - OptionSW in slot C0 is too old
1302 - OptionSW in slot C1 is too old
1315 - Option SW in slot A is not sup-
ported (not allowed)
1316 - Option SW in slot B is not sup-
ported (not allowed)
1317 - Option SW in slot C0 is not sup-
ported (not allowed)
1318 - Option SW in slot C1 is not sup-
ported (not allowed)
2315 - Missing SW version from power unit.
WARNING 59
Current limit:
The current is higher than the value in par. 4-18.
WARNING 61
Encoder loss:
Contact your Danfoss supplier.
WARNING 62
Output Frequency at Maximum Limit:
The output frequency is higher than the
value set in par. 4-19
ALARM 63
Mechanical Brake Low:
The actual motor current has not exceeded
the "release brake" current within the "Start
delay" time window.
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 Over Temperature:
Control card over temperature: The cut-out
temperature of the control card is 80° C.
WARNING 66
Heatsink Temperature Low:
The heat sink temperature is measured as 0°
C. This could indicate that the temperature
sensor is defective and thus the fan speed is
increased to the maximum in case the power
part or control card is very hot.
ALARM 67
Option Configuration has Changed:
One or more options has either been added or
removed since the last power-down.
