Troubleshooting
WARNING/ALARM 58
AMA internal fault:
Contact your Danfoss supplier.
WARNING 59
Current limit:
The current is higher than the value in par. 4-18.
WARNING 62
Output Frequency at Maximum Limit:
The output frequency is limited by the
value set in par. 4-19
ALARM 63
Mechanical Brake Low:
The current 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 current DC link voltage.
WARNING/ALARM/TRIP 65
Control Card Overtemperature:
Control card overtemperature: The cut-out
temperature of the control card is 176°F [80°C].
WARNING 66
Heatsink Temperature Low:
The heatsink temperature is measured as 32°F
[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.
ALARM 70
Illegal Frequency Configuration:
Current combination of control board and
power board is illegal.
ALARM 80
Drive Initialized to Default Value:
Parameter settings are initialized to the
default setting after a manual (three-finger)
reset or via par. 14-22.
