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.
WARNING/ALARM 58, AMA internal fault:
Contact your supplier.
WARNING 59, Current limit:
The current is higher than the value in par. 4-18
Current Limit
.
WARNING 60, External Interlock:
External Interlock has been activated. To resume normal operation, apply
24 VDC to the terminal programmed for External Interlock and reset the
frequency converter (via Bus, Digital I/O or by pressing [Reset]).
WARNING 62, Output Frequency at Maximum Limit:
The output frequency is limited by the value set in par. 4-19 Max Output
Frequency
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, Low Temp.:
The heat sink temperature is measured to be low. 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 68, Safe Stop:
Safe Stop has been activated. To resume normal operation, apply 24 VDC
to terminal 37 then send a Reset signal (via Bus, Digital I/O or by pressing
[Reset]).
ALARM 69, Pwr. Card Temp:
Power card over temperature.
WARNING 76, Power Unit Setup:
The required number of power units does not match the detected number
of active power units.
ALARM 70, Illegal Frequency Converter Configuration:
Actual combination of control board and power board is illegal.
ALARM 90, Feedback Mon.:
ALARM 92, NoFlow:
A no load situation has been detected for the system. See parameter
group 22-2*.
ALARM 93, Dry Pump:
A no flow situation and high speed indicates that the pump has run dry.
See parameter group 22-2*
ALARM 94, End of Curve:
Feed back stays lower than the set point, which may be indicates a leak-
age in the pipe system. See parameter group 22-5*
ALARM 95, Broken Belt:
Torque is below the torque level set for no load indicating a broken belt.
See parameter group 22-6*
ALARM 96, Start Delayed:
Start of the motor has been delayed due to short cycle protection is ac-
tive. See parameter group 22-7*.
ALARM 220, Overload Trip:
Motor overload has tripped. Indicates excess motor load. Check motor
and driven load. To reset press the "Off Reset" key. Then, to restart the
system, press the "Auto On" or "Hand On" key.
WARNING/ALARM 243, Brake IGBT:
The brake transistor is short-circuited or the brake function is disconnec-
ted. Turn off the frequency converter as a fire precaution. Report value
indicates source of alarm (from left): 1-4 Inverter 5-8 Rectifier.
WARNING/ALARM 244, Heatsink Temp:
Drive heatsink over temperature: Report value indicates source of alarm
(from left): 1-4 Inverter 5-8 Rectifier.
ALARM 245, Heatsink Sensor:
No feedback from the heatsink sensor Report value indicates source of
alarm (from left): 1-4 Inverter 5-8 Rectifier.
ALARM 246, Pwr. Card Supply:
The supply on the power card is out of range Report value indicates
source of alarm (from left): 1-4 Inverter 5-8 Rectifier.
ALARM 247, Pwr. Card Temp:
Power card over temperature Report value indicates source of alarm
(from left): 1-4 Inverter 5-8 Rectifier.
ALARM 248, Illegal PS Config:
Power size configuration fault on the power card Report value indicates
source of alarm (from left): 1-4 Inverter 5-8 Rectifier.
ALARM 250, New Spare Part:
The power or Switch Mode Power Supply has been exchanged. The fre-
quency converter type code must be restored in the EEPROM. Select the
correct type code in Par 14-23 according to the label on unit. Remember
to select ‘Save to EEPROM’ to complete.
ALARM 251, New Type Code:
The frequency converter has got a new type code.
