FC 300 Instruction Manual
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 is increased. In most
cases, however, this is not critical.
ALARM 58
AMA internal fault:
Contact your Danfoss supplier.
WARNING 59
Current limit:
Contact your Danfoss supplier.
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 176 °F (80 °C).
WARNING 66
Heatsink Temperature Low:
The heat sink temperature is measured as 0° C. This
could indicate that the temperature sensor is defect
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.
Troubleshooting
ALARM 68
Safe Stop Activated:
Safe Stop has been activated. To resume
normal operation, apply 24 V DC to terminal
37, then send a reset signal (via Bus, Digital
I/O, or by pressing [RESET]).
ALARM 80
Drive Initialized to Default Value
Parameter settings are initialized to default setting
after a manual (three-finger) reset.
