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 combinations demand a motor voltage higher than
the actual DC link voltage.
WARNING/ALARM/TRIP 65, Control Card Overtemperature:
Control card over temperature: 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 that the fan speed has in-
creased to maximum, if 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 overtemperature.
ALARM 70, Illegal Adjustable Frequency Drive Configuration:
Current combination of control board and power board is illegal.
ALARM 90, Feedback Mon.:
ALARM 91, Analog Input 54 Wrong Settings:
Switch S202 must be set in position OFF (voltage input) when a KTY sen-
sor is connected to analog input terminal 54.
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 indicate that the pump has run dry.
See parameter group 22-2*
ALARM 94, End of Curve:
Feed back stays lower than the setpoint, 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 that is
active. See parameter group 22-7*.
ALARM 250, New Spare Part:
The power or switch mode power supply has been exchanged. The ad-
justable frequency drive 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 adjustable frequency drive has a new type code.
