al arm 54, ama motor too small:
The motor is too small for the ama to be carried out.
al arm 55, ama par. out of range:
The par. values found from the motor are outside
acceptable range.
al arm 56, ama interrupted by user:
The ama has been interrupted by the user.
al ar m 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 Armstrong 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 v dc to the terminal programmed for Ex-
ternal Interlock and reset the inverter (via Bus, Digital i/o or by
pressing Reset).
warning/alarm 61, Tracking Error:
Tracking error. Contact your supplier.
warning 62, Output Frequency at Maximum Limit:
The output frequency is limited by 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 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 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. If the temperature is below 59°f (15°c)
the warning will be present.
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.
alarm 70, Illegal Frequency Converter Configuration:
Actual combination of control board and power board is illegal.
alarm 90, Feedback Mon.:
alarm 91, Analogue Input 54 Wrong Settings:
Switch s202 has to be set in position o (voltage input), when a
kty sensor is connected to the analogue input terminal 54.
alarm 92, No Flow:
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 protec-
tion is active. See parameter group 22–7*.
alar m 250, New Spare Part:
The power or Switch Mode Power Supply has been exchanged.
The inverter type code must be restored in the eeprom. Select
the correct type code in par. 14–23 Type code Setting accord-
ing 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.
15.0 acoustic noise and vibration
If the pump or the pipework close to the pump is making noise
or vibrations at certain frequencies, try the following:
•SpeedBypass,parameters4–6*
•Over-modulation,parameter14– 03 set to o
•Switchingpatternandfrequencyparameters 14– 0*
•ResonanceDampening,parameter1–64
